We are one of the Gost pn16 wn flanges manufacturers, Metleader pipeline tech inc, manufactures and exports all kinds of gost flange to many regions and countries. In the past 36 years, we specialized in the production of various types of large diameter, small-diameter carbon steel flange, stainless steel flange, the United States standard flange, Russian standard flange, Japanese standard flange, etc., can be made for illustration. All raw materials procurement from the mainstream of large steel mills, to ensure that chemical components and a variety of mechanical properties and other standards. The use of forging, CNC lathes and other advanced processing methods, finished flange reached two standard forgings, flange size precision surface finish high, no burr. Packaging using bubble bags and wooden cases or cartons, effectively avoid the impact of the transport process, to provide customers with the best products, the most preferential prices.
1. ASME Flange
Nominal pressure: PN2.0, PN5.0, PN11.0, PN15.0, PN26.0 and PN42.0 6 pressure levels.
Nominal diameter: dn15~dn1500.
Flange type: With neck flat welding, with neck butt welding, integral flange, socket welding, thread, loose sleeve, etc. 6 kinds.
Sealing type: surface, concave-convex surface, tenon groove surface, ring connection surface, full plane, etc. 5 types. The chemical industry pressure Piping Application standard system is also a relatively complete standard system, and has undergone several years of production practice test, has the mature use experience. Because it also has "large OD series" and "Small OD series", "European-style flange" and "American Flange" two series, so its use is relatively wide, it can be with foreign ANSI, DIN, ISO and other standards with the use, but also with the domestic GB, SH, JB and other standards with the use. Common standards in the application standard system of Chemical industry. 2.GOST Flange: (GOST12815-80)
