ASTM Specifications for Pipe
It is an old saying that industry and standards go hand in hand. The production as well as testing gets may vary because of the variation in different organization standards for wide application ranges. The buyer first needs to understand the basics of different industrial specifications for their projects, have a glance at the below paragraph.
ASTM
ASTM stands for American Society for testing and materials. ASTM International offers service standards and industrial materials over a wide range of sectors present in industries. This particular organization has served 12000+ standards presently that got used in industries all over the globe.
Nearly 100+ standards pertain to stainless steel pipes and fittings. ASTM covers nearly all varieties of pipes, unlike other standard organizations.
For example- a full range of pipe gets stocked as American pipe products. For high-temperature services, seamless carbon pipes get used with appropriate standards. The determination of chemical composition and specific manufacturing processes related to material defines the ASTM standards.
The permitted quantities are magnesium, nickel, carbon etc., by "Grade".
For example- Grades A and B help in the identification of carbon steel pipe. Furthermore, ASTM grades can be arranged according to flanges, pipes, fittings and nuts.
ASTM Material
A106 -these specifications gets used for high-temperature services
A335 – for high-temperature services, seamless ferritic steel pipe
A333 -for low-temperature usage, welded and seamless alloy steel pipes gets used
A312 – for general corrosive service and high-temperature service, cold-worked welded, straight seam welded, and seamless pipes are used
ASTM standards are instrumental in testing, evaluating mechanical, and installation requirements, and designing and specifying pipes.
GNEE Steel provides various grades of stainless steel pipes according to ASTM standards:
