Understanding ASTM B730 Welded Tube Specification
ASTM B730 is a standard specification that envelops welded nickel and nickel-copper alloy tubes that are offered in an annealed or stress relieved state. The tubes are designed to be used in general corrosion-resistant and mechanical purposes, where both structural stability and chemical stability are needed.
In comparison to seamless tubing, ASTM B730 welded tubes are actually manufactured by controlled welding and then heat treatment. This guarantees homogeneous microstructure, enhanced ductility, as well as constant mechanical properties along the tube length. The specification gives specifications on requirements associated with the chemical composition, mechanical properties, dimensional tolerances, and testing procedures.
The ASTM B730 welded tubing that is supplied by Shubham Metals is in compliance with ASTM B730 and ASME SB730 and hence can be used in both domestic and international projects.
Alloy Grades Covered Under ASTM B730
Specific nickel-based alloys that are known to be corrosion-resistant and thermostable are used to make ASTM B730 welded tubes. Nickel 200, Nickel 201 and Nickel-Copper Alloy 400 (Monel 400) are the most popular supplied grades.
Nickel 200 (UNS N02200) is a commercially pure nickel that has a high level of alkaline resistance and neutral chemical resistance. It is commonly chosen when using in caustic solutions and food processing machines.
A low-carbon Nickel 200 is nickel 201 (UNS N02201). The lower carbon content eliminates precipitation of graphite at high temperatures hence it is more likely to be used in the high temperature service.
Nickel-Copper Alloy 400 (UNS N04400) also referred to as Monel 400 has an excellent performance in seawater, hydrofluoric acid, sulfuric acid, and several other corrosive media. It also has increased mechanical strength with respect to pure nickel grades.
Chemical Composition of ASTM B730 Welded Tubes
Some chemical compositions of ASTM B730 welded tubes vary, based on the grade of alloy used, however, there are strict limits that are observed to guarantee uniform performance and corrosion resistance.
