Construction

Stainless steel welded pipe is corrosion resistant and this type of material is extremely durable in harsh conditions.

ASTM A333 and ASTM A334 are both specifications for seamless and welded carbon and alloy steel pipes used for low-temperature service. Specifically, ASTM A333 covers a range of steel grades suitable for temperatures as low as -50°F (-45°C), while ASTM A334 is intended for temperatures as low as -150°F (-101°C).

GB/T 18248 seamless gas cylinder tube is a kind of seamless steel tube for gas cylinders.

ASTM A250 steel pipe is an alloy steel pipe produced according to the American Society for Testing and Materials (ASTM) standard. It is mainly used to manufacture boilers, superheaters, heat exchangers and other equipment in the oil, natural gas, power and other industries.
