Description
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of astm a403 wp321-s 180° short radius elbow in China. With abundant experience, we warmly welcome you to wholesale customized astm a403 wp321-s 180° short radius elbow from our factory. For price consultation, contact us.
GNEE is a professional manufacturer of stainless steel pipe fittings that fully comply with the ASME SA403M standard.
We supply ASTM A403 WP321-S 180° short radius elbows, which are fittings made from 321 stainless steel and designed to change the flow direction by 180° using a short radius (with a bend radius smaller than that of long-radius elbows). These elbows are suitable for pressure piping systems.
ASTM A403 WP321 fittings achieve enhanced resistance to intergranular corrosion through the addition of titanium (Ti), with a content of 5×(C+N) to 0.7%. They are commonly used in high-temperature environments and are connected using butt-weld ends. The available size range is from 1/8 inch to 4 inches, meeting standards such as ASME B16.9, so both small and medium-sized pipes and fittings comply with these requirements. In addition, these fittings must undergo hot forming and annealing to eliminate internal stress.
