About JS Fittings - Pipe Fittings and Flanges Supplier in China

JS Fittings is based in China and lists 26 active products in its catalogue. The company focuses on pipe fittings and flanges, covering the top categories of Flanges and Steel Pipes. Products include carbon steel pipe elbows (HS code 7307.93), welded flanges (HS code 7307.91), blind flanges (HS code 7307.21), and various tees and elbows made from carbon steel, stainless steel 304/316, and alloy steels. Each item specifies the applicable material grade such as ASTM A234 WPB, A105, or A182 F304/F316. The HS codes fall within Chapter 73, which classifies articles of iron or steel.

The catalogue differentiates between butt‑weld, forged, and RTJ (ring‑type joint) designs, with items like Carbon Steel Butt Weld 45/90/180 Degree Elbow (7307.93) and ASME/ANSI B16.5 Steel Flange (7307.91). Materials range from carbon steel grades (A105, A234 WPB/WPC) to stainless steel grades (304, 304L, 316, 316L) and alloy steels (F5, F11, F22). Many entries cite ASTM and ASME standards, indicating compliance with international pipe‑fitting specifications. The product set also includes malleable iron tees (HS 7307.99) and PE‑coated steel fittings. All listings are organized under the HS‑code families 7307.19, 7307.21, 7307.91, and 7307.93.

Product Range and Specialties of JS Fittings

JS Fittings offers a catalogue that spans carbon‑steel elbows, tees, and bends (HS 7307.93), forged and welded flanges (HS 7307.91, 7307.21, 7307.19), and specialty items such as malleable‑iron tees (HS 7307.99).
