JIS G3472 is the Japanese industrial standard for resistance welded carbon steel pipes for automotive structures.

S275JR and S355JR hot dip galvanized pipes‌ are specially designed for compressed air applications. They meet the requirements of European standards (EN standards) and have excellent mechanical properties and corrosion resistance.

ASTM A556 steel pipe is a seamless carbon steel pipe for feedwater heaters, usually used in boiler low, medium and high pressure heat exchangers and heat exchangers for petrochemical industry.

‌ASME SA213 T11, T12, T22 seamless alloy pipes‌ have high strength and high corrosion resistance, and can meet the requirements of use in various complex environments.

As a kind of seamless steel pipe, the performance of alloy pipe is much higher than that of general seamless steel pipe. This is mainly because the alloy pipe contains more chromium elements, which makes it have excellent high temperature resistance, low temperature resistance and corrosion resistance.
