Duplex Stainless steel tubes

The microstructures inside duplex stainless steels are approximately 50 percent austenite and 50 percent ferrite, and consequently, duplex products share the physical properties of both ferritic and austenitic grades. Duplex stainless steels are resistant to the cracking caused by chloride stress corrosion in austenitic grades and have improved resistance to localized corrosion. This family of stainless steels has roughly twice the yield strength of their counterpart austenitic grades which means we can use it to design thinner gauge tubing. Higher hardness values provide better wear resistance for high precision tubes.

Duplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex. This family of alloys has great advantages in both material and engineered fabrication costs.

Typical applications for this alloy group include heat exchanger tubes, umbilicals, structural tanks, pulp and paper making equipment, pipes and fittings, and seawater handling systems.

STAINLESS STEEL PIPES & TUBES

Application in high demanding industries and sectors, particularly high temperature and corrosive services.

Stainless steel seamless pipes and stainless steel seamless tubes are reliable long lasting and on par with international quality and safety norms

Stainless Steel ERW, EFW and Stainless Steel Seamless Pipes and Stainless Steel Seamless tubes.

Applications include attractive appearance, corrosion resistance, low maintenance and strength of stainless steel.

Stainless steel is more expensive than standard grades of steel but it has greater resistance to corrosion, needs low maintenance and has no need for painting or other protective coatings.

These factors mean stainless steel can be more economically viable once service life and life-cycle costs are considered.

Cold Drawn Tubes Cold Drawn Seamless (CDS) as implied is made by cold drawing a larger mother seamless pipe, which is generally manufactured through an HFS process. In the CDS process, the mother pipe is pulled through a die & plug in cold without any heating. Because of the tool on the outside and inside the surface and tolerances are better in CDS. While this is an additional process over HFS, it is necessary to get smaller size pipes which otherwise cannot be manufactured in HFS. Some applications which require close tolerances and smooth surfaces also specify the requirements to be necessarily CDS. CDS pipes & tubes are extensively used in Heat-Exchanger, Bearing & Automotive sectors.

 Copper Tubes

Copper is light, strong, corrosion-resistance, long lasting and maintenance free. Its high thermal conductivity and ease of joining, bending and handling often make it the metal chopice for tubing. Copper tube will not burn or support combustion or decompose toxic gases. Therefore, it will not carry fire through floors, walls, and ceilings. Volatile organic compounds are not required for installation.

Amco Metals provides a full range of copper products for almost any application. Our strip, coil, foil, bar, rod, pipe, plate, sheet, tube and other profiles are produced in a wide variety of copper alloys, including clad composites. They can be produced in standard dimensions or custom made to your requirements.
