Flange

Product Overview

Flanges are key components for detachable connections between pipes and equipment, valves, and other piping systems. Our company manufactures them according to standards such as ASME B16.5, EN 1092-1, BS 4504, and JIS B2220. Materials include carbon steel (ASTM A105), stainless steel (A182 F304/316L), and alloy steel (F11/F22). Types include flat-face flanges (SO), weld neck flanges (WN), blind flanges (BL), socket flanges (SW), and threaded flanges (TH), with pressure ratings ranging from 150LB to 2500LB. Sealing surfaces include RF, FF, RTJ, and MFM.

Product Details

Product Advantages

Various sealing surfaces are available to adapt to a wide range of gaskets and operating conditions.

100% ultrasonic or magnetic particle testing (welded flange), hardness and chemical composition re-inspection.

Complete accessories: We can provide flange gaskets, bolts and nuts simultaneously, enabling one-stop procurement.

CNC machining ensures bolt hole center distance tolerance ≤0.5mm and good interchangeability.

Anti-corrosion Plastic-coated Pipe Fittings

Using carbon steel (Q235B, 20#) or ductile iron as the base material, the inner and outer surfaces are coated with an epoxy resin (EP) or polyethylene (PE) anti-corrosion layer with a thickness of 200~500μm through electrostatic spraying or hot-dip plastic coating. Compliant with standards such as CJ/T 120, GB/T 28897, and DIN 30670, including plastic-coated elbows, tees, reducers, flanges, etc., suitable for water supply, drainage, fire protection pipelines in buried or humid environments.

Stainless Steel Pipe Fittings

Meets ASME B16.9, B16.11 and ASTM A403/A182 standards. Materials primarily include 304/304L and 316/316L, but high-alloy steels such as 321 and 310S are also available. A complete range is offered: 90°/45° elbows, equal/reducing tees, concentric/eccentric reducers, pipe caps, crosses, etc., sizes 1/2″~48″ (DN15~DN1200), wall thickness SCH10~SCH160. Widely used in pipelines handling clean and corrosive media in chemical, food, and pharmaceutical industries.

Thermoplastic Pipe Fittings

Made from thermoplastic materials such as high-density polyethylene (HDPE), polypropylene (PP), or polyamide (PA12), these products are formed through injection molding or hot-melt welding. Products include electrofusion sleeves, electrofusion elbows, electrofusion tees, socket fittings, and flange joints, conforming to standards such as ISO 4427, EN 12201, and ASTM F714. Suitable for pressure and non-pressure piping systems in applications such as gas, water supply, chemical, and trenchless repair.
