Technical regulation and scope of pipes according to ASTM B730 standard
The ASTM B730 standard (analogous to ASME SB 730) defines strict requirements for the production of welded pipes made from corrosion-resistant nickel and nickel-copper alloys. The range of materials covered by this specification includes: pure nickel (UNS N02200), low-carbon nickel (UNS N02201), and Monel alloy (nickel-copper, UNS N04400).
EV Group China’s production technology eliminates the use of filler materials during welding, which guarantees the uniformity of the structure of the weld and the base metal. To ensure high performance and corrosion resistance in the heat-affected zone, each pipe undergoes mandatory heat treatment (annealing or quenching and tempering) followed by final cold calibration.
This type of metal product is in demand in high-tech engineering systems, including the production of sensitive thermostat elements, components of industrial electric heating systems, and equipment operating in aggressive environments.
Technical parameters in the standard are provided in the inch-pound system as priority. Converted values in the SI system are for reference only. Industrial safety issues and product handling regulations are determined by the current Material Safety Data Sheets (MSDS) provided by EV Group China upon delivery of products.
