Product Introduction

ASTM A312 TP 904L Pipe Suppliers in China
SS 904L Pipe consists of chromium, nickel and copper. Copper is added to the 904L Stainless Steel Pipe alloy, therefore, it is very resistant to strong reducing acids such as sulfuric acid. The lower carbon content makes AISI 904L welding pipe easier. ASTM 904L is mainly used for general corrosion applications.

AISI904L Stainless Steel Seamless And ERW Pipe

SS 904L Pipe including Seamless and Welded Pipes (ERW, EFW, SAW) are made of nickel-chromium alloy with lower carbon content. 904L stainless steel seamless pipe has strong pressure bearing capacity, large-diameter welded pipe has low cost, suitable for large flow liquid of oil and gas, and high efficiency.

904l Stainless Steel Seamless Pipe Test

According to ASTM A312, each 904l tubing must be supplied in heat-treated state with appropriate heat treatment temperature and cooling and testing.
