Advantages of ASME BPE fittings in pharma piping requirements

Advantages of ASME BPE fittings in pharma piping requirements

As one of ASME’s over 500 codes and standards, the ASME BioProcessing Equipment (BPE) Standard was launched in 1997.

A core concern of ASME BPE Tube Fitting standards is the consistency of weldability using orbital welding. We designed straight lengths of fittings such as Bends and Tees specifically taking into account the clamping requirements in orbital welding machines. Weld ends can be made more sulphur-free by introducing controlled levels of sulphur (between 0.005-0.017). The standard has also addressed the issue of weld beads that are consistent.

In addition to electro-polished and mechanical polished options, ASME BPE tube fitting standard extends flexibility for end-users in specifying internal finishes based on specific applications.

Several component and equipment manufacturers were unable to manufacture fittings, tubing, and process components or equipment to the same critical dimensions or standards, which led to the ASME-BPE Standard. It was not a widely accepted standard in the early eighties when this issue was addressed by the bioprocessing industry. A common problem in field installations was that fittings, tubing, and process components could not be welded.

The ASME Winter Meeting (WAM) in San Francisco in 1988 brought together manufacturers and end users to discuss the development of meaningful bioprocessing standards. Several subcommittee meetings were conducted in 1990, leading to the publication of the first BPE Standard in 1997.

Additionally, the BPE Standard evolved to meet the needs of the biopharm industry. In addition to defining dimensions and tolerances for fittings, tubing and process components; the standard also addresses: the design of fittings, components, and equipment, material joining, surface finishing, seals, metallic materials of construction, and polymer-based materials.

There are now over 30 countries that recognize the ASME BPE 20009 Standard that is on par with international standards for bioprocessing, pharmaceuticals, and personal care products.

The ASME BPE system has made it possible for end users to choose from a variety of suppliers to find fittings and tubing of consistent quality for their projects and be assured that there will be no problems with welding, interchangeability, or intermixing since the fittings are all designed to one standard.

We are one of the world’s largest manufacturers of ASME BPE tubes & fittings. They have a state-of-the-art facility with the latest manufacturing technology, quality management, and related documentation. Creating better standards for hygienic applications is Kinglai’s responsibility as a member of the ASME BPE committee.

In addition to its worldwide sales operations, RatnaExporter.com has an impressive customer list that contains most of the major international pharma companies. The distributor of RatnaExporter.com in India is Inline Technologies, Bangalore.

As a result of Inline Technologies’ large local stock of ASME BPE tube and fitting products, all immediate and project needs of pharma companies can be met.

Among other applications with relatively high levels of hygienic requirements, this ASME Standard provides requirements for the design of equipment used in bioprocessing, pharmaceutical, and personal care products industries. Material, design, fabrication, inspections, testing, and certification are all covered.

The ASME-BPE standard is unique in the world, having been developed in response to widespread industry requests for standardization. The standard specifies how equipment and systems for the manufacture of biopharmaceuticals should be designed and built. Current best practices are incorporated to improve the purity and safety of the product. By applying ASME-BPE rigorously, companies are often able to improve production efficiency, decrease development and manufacturing costs, increase quality and safety, and remain in compliance with regulations.

what is BPE?

Stainless steel grades 304 and 316 are typically available. B PE fittings can only be used with 316L stainless steel. 

There is another feature that can distinguish the two, in addition to the end styles. Can you tell me if you have experience fitting BPE lines on I lines? There has never been an incident like this. Hygienic triclamps and butt welds are the two types of end caps available. 

BioProcessing Equipment has a variety of fittings called High-Purity Fittings instrument tee or BPE or BioProcessing Equipment Fittings. A number of requirements are met by these fittings, including tighter tolerances, cleaner interior surfaces, and higher quality materials than 3A standard fittings.

What is the difference between ASME BPE and 3A

BPE fittings are all regulated as far as quality assurance is concerned. Verification is conducted with the help of a Niton gun. In order to ensure they are receiving the correct material, the user can easily determine the chemical composition of the material with a single click.

Aside from material availability, there is another difference worth mentioning. Two types of stainless steel fittings are commonly available: 304 and 316. Only SS316L fittings are available for purchase with BPE fittings. There are other things apart from the end styles that really stand out. Is it possible for you to tell me if you have ever seen BPE fittings with I lines? I don’t believe that. There are two types of fittings available in the BPE system: buttweld and hygienic triclamp.

Now that we have established the importance of surface finish, let’s move on. In addition to the sanitary surface finish on 3A fittings, BPE fittings also have this finish. Surface finishes with a sanitary finish are typically those with a Ra of 32 or higher. Fittings meeting and often exceeding this standard are usually considered 3A. The BPE fittings also come in several different types. It is the #3 PC or SFF1 finish that is referred to as the ‘standard’ BPE finish. The ID of this finish has been mechanically polished, but the OD has not been polished. Some BPE fitting lines offer a light OD polish on their PC and PD fittings, which are usually insulated. In most cases, BPE fittings are finished with #7 or PL finishes, which have a mechanical ID finish of 20 Ra and an OD polish of 32 Ra. It is common to see these fittings on a pharmaceutical process skid that does not have insulation. Fittings 

What is the difference between ASME BPE and 3A

asme bpe standard such as these will be found on an uninsulated pharmaceutical manufacturing skid. We now move on to the electropolish finishes – PL and PM – following the PL and PC finishes. A total of 15 Ra IDs with EPs and polished or unpolished ODs go.bpe are available in these finishes. This additional finishing option is one of the reasons why asme BPE fittings standards are generally more expensive than 3A fittings.

On the basis of 304 3A fittings, where the certificates for heat certificates are not even available, and 316 fittings, where they are not always available, there is also a significant difference in availability of lot and material traceable certificates between 3A and BPE fittings. As opposed to these fittings, BPE fittings and asme bpe flange almost never ship without these certifications.

These are just a few of the similarities between BPE and tangent of 45 3A fittings. In addition to sanitary fittings, tubing, pumps, and valves, we also have the largest inventory. Because we have decades of combined experience, we will ensure that you get the right fitting the first time.

The 3A and BPE fittings are both considered sanitary. Both tubes are measured by the outer diameter in the same manner as sanitary tubes. As a result, you can solder both fitting types. What are the similarities between the two? It is considered sanitary to use both BPE pipe and 3A fittings. The outer diameter of the tube is measured the same way as that of a sanitary tube. It is therefore possible to solder both fittings together. The clamps are also the same size. It’s a similar place, but there are some key differences that will be discussed in the rest of the article.

With the development of the dairy industry, ASMEBPE developed its own fittings standard. To indicate that these fittings are specifically designed for dairy applications, they are marked with the 3A symbol. As rail horns are extensively used in welding procedures used to connect pharmaceutical fittings, this fitting has an extended section to accommodate them. Fittings for bioprocess equipment must meet the dimensions described in the standard. The BPE fittings must be completely drained once they have been installed.

A material

Another difference to emphasize is the availability of materials. BPE fittings are usually only available in 316L steel, while 3A fittings are usually available in 304 and 316 steel. Regarding the I-LINE BPE fittings you have seen, the answer is no, as BPE has only special welding and clamping ports. Aside from I-LINE, John Perry, tangent 45 and Q-LINE, there are no other sanitary fittings available.

The treatment of a surface

It is our belief that the surface finish of both 3A and BPE fittings is hygienic. It is c ommon for 3A fittings to meet and often exceed this specification. Generally, a hygienic surface treatment is defined as one that has a Ra value of 32 or higher. It is important to note, however, that BPE has several additional specifications.

A topic we’ve focused on a lot in the past is sanitary fittings- both BPE and 3A fittings, but this is still something that comes up a lot as when we talk to customers. People who are not intimately familiar with the industry can struggle to distinguish between regular sanitary or 3A fittings and BPE fittings. This post will cover the similarities and the differences between the two fittings and hopefully clear up a simple misconception.

BPE and 3A Sanitary Fittings- What's the Difference?

To start, how are the two similar? B.P.E Well, both asme BPE flages and 3A fittings are considered sanitary. Both are measured in the same way sanitary tubing reduces is- by tube OD. We’ve talked about this in the past. This means you could weld the two fitting types together. The triclamp dimensions for the for the two are also exactly the same- which means whether you’re looking for 3A or BPE fittings, you’re just as likely to confuse 1” or 1.5” fittings s2s . Some of the fittings also have the same overall dimensions. Both the 14WMP and BPE S14WMP short welding ferrules, for bpe meaning instance, have the same OAL sup end.

That is about where the similarities end, we’ll spend the rest of this post highlighting some of the differences between the two.

3A fittings have their roots in the dairy industry. They are marked with the 3A symbol which lets customers know that these fittings are designed specifically for use in the dairy applications. As the industry evolved, an ASME subgroup, known as the BPE, developed their own standards for fittings. These fittings needed extended tangent 45 to accommodate the orbital weld heads used heavily in the autogenous welding procedures used in the joining of pharmaceutical fittings tangent of 45. BPE fittings dimension are requirements are outlined in the Bioprocess Equipment standard. ASME BPE fittings are designed specifically to be fully drainable when properly installed.

BPE and 3A Sanitary Fittings- What's the Difference?

Another difference that should be highlighted is material availability. 3A fittings are commonly offered in both 304 and 316 stainless steel. BPE fittings are offered exclusively in 316L SS. The next thing that really sticks out is the end styles. Have you ever seen I line BPE fittings? The answer is no. BPE fittings are available in exclusively butt weld and hygienic triclamp ends. You won’t see the I line, John Perry, or Q line fittings available in other sanitary fitting styles.

Now, let’s talk surface finish. Both 3A and BPE fittings have what we consider “sanitary” surface finish. Sanitary surface finishes are generally considered any finish that is 32 Ra or better. 3A fittings meet this spec and often exceed it. BPE fittings, however, come in several additional flavors. The “standard” BPE finish is the #3 PC or SFF1 finish. The #3 finish has a 20 Ra Mechanical ID polish and an unpolished OD. Some BPE fitting lines, such as VNE’s Maxpure, even feature a light OD polish on their PC and PD fittings (which are generally insulated). The most common BPE finish is the #7 or PL finish. This is a 20 Ra mechanical ID finish and a 32 Ra polished OD. These are the fittings you’ll see on an uninsulated pharmaceutical process skid. After the PL and PC finishes, we get into the electropolish finishes- PL and PM. These finishes feature a 15 Ra ID w/ EP and either polished or unpolished OD’s. These additional finish options are the biggest reason why BPE fittings are generally more expensive than 3A fittings.

Another difference you’ll see between 3A and BPE fittings is the availability of lot and material traceable certs. On 304 3A fittings, you can’t even get heat certs and on 316 they still aren’t always available. BPE fittings, on the other hand, almost never ship without them. VNE’s MaxPure fittings even ship with a QR code on the package that allow a smartphone to almost instantly retrieve the MTR. Material traceability and verification are absolutely critical in the pharamcetuical process world.

So there you have it- just a few of the similarities between BPE and 3A fittings.
