Product description

All the company's flange products are produced by the most advanced computer numerical control lathe, and at the same time, the advanced inspection equipment is used to strictly control the market in each production link, so that each product is deeply imprinted with the word "fine". We has undergone rigorous tests time after time.
We choose the best materials, which is the consensus of the company's growth and development. All products of the company are produced in strict accordance with 1CB1249.SH, HGI NST, 118, DN, 150 and other standards, and use 304, 3371, 3041, 316, 3161, 2520, 31803, 04 groups of mesh, mesh, heat-resistant steel, silver copper, specializing in the production of various commercial 1 alloy and Lili alloy flanges, NCON11 alloys, such as: NCONE1625, NCONE1600, NCONE718, NCONE175 NCoNE601 ;, NColo alloys, such as Ncolor800, NColloY825, Mcollor020, NColor028, NCollor25, MONEl alloys MoNEl40, MoNEK500: Hastelloy alloys, such as: HASTEllorC276, HASTEllorC22HASTEllorC4, HASTEllorCHASTEll ATElorB. As a product raw material, it effectively controls the original quality of the product. It is the company's original philosophy to produce richer products and develop a more emotional and real brand. The company produces a series of flat-cut flanges, flanges between snails, flat-circumferential flanges, and concave-convex flanges. Sanitary flanges and American, German, national and other legal products can be widely used in petroleum, chemical, food, metallurgical construction, electric power and other engineering industries. The product diameter is DN5mm to DN5000mm, which can fully meet various fields. Various standard ranges are used.
