  • SO / Slip On FlangeThe short raised neck that can enhance its mechanical strength and load capability, so it can be used onto the conveyance pipeline with a pretty high hydraulic pressure.
    The surface glossiness is pretty high, and the mechanical properties are reliable.
    A variety of specifications are for option.
  • SW / Socket Weld FlangeIt is very easy and safe to be used. Ascribing to the advanced production craft and high quality material, our product shows high mechanical strength, hardness, wear resistance, and corrosion resistance, so it has been widely used in the pressure vessel, petroleum industry, chemical industry, ship making, pharmacy, metallurgy, machinery, mechanical elbow making, and food processing.
  • WN / Weld Neck Pipe FlangeIt shows terrific deformation resistance and sealing property, thus it is suitable to be used onto the pipeline with drastic pressure or temperature fluctuation inside, and the high pressure pipe with extremely high or low temperature inside, as well as the conveyance pipeline of expensive or combustive fluid media.
  • TH / Threaded Pipe FlangeThe threaded pipe flange attaches is widely used in the pipeline engineering, for it is fairly convenient to be attached to the pipe with no need of welding, and can withstand the a wide range of hydraulic pressure ranging from 1.0MPa to 2.5MPa. We provide the stainless steel, carbon steel and alloy steel threaded pipe flanges that can be extensively used in the fields
  • BL / Blind FlangeThe blind flange belongs to the non-hubbed type that is specially used to block the pipe. It is applicable in the fields, including the pressure vessel making, petroleum conveyance, chemical industry, ship making, pharmacy, metallurgy, machinery manufacture, food process, etc.
  • PL /Plate Weld FlangeThis product has simple production process and low production cost. It can be customized upon request of customer about the specification, product standard, and quantity. For a record, due to the ordinary mechanical rigidity, the plate weld flange is rarely used onto the conveyance pipeline of chemical media that are combustive, explosive or air-isolated.
  • LWN / Long Welding Neck FlangeThe production process of our long welding neck flange contains the sectioning, forging, solution treatment, fine machining, drilling, quality testing, etc.
    The high quality neck part shows good mechanical stiffness and load capability.
    Compared with the butt welding flange, this product has higher electrode consumption.
  • Spectacle Blind FlangeThe spectacle blind flange is a pipe fitting used to connect two big inner diameter pipes. Its structure usually consists of the two flange pieces of which one is hubbed but the other is blind, and the two flange pieces are bound with each other via some fasteners. Figuratively, it looks exactly like the Arabic numeral 8 with the upper half is not hollow.
    1. Carbon Steel FlangeOur carbon steel flange is made of ASTM A105, ASTM A350 LF2, ASTM A694/F42, F52/F60/F65/F70, or other high grade carbon steel material. It has lower price than stainless steel flange, and applies to the water pipeline system. The pipeline using this pipe fitting can be easily maintained by changing the damaged section rather than changing the whole pipe system, and be blocked easily in any position inside.
    1. Alloy Steel FlangeThe alloy steel flange shows better strength, toughness, wear resistance, etc. than the carbon steel flange for the metallic elements inside and special forging craft. Its material can be chosen by customer among ASTM A182 F1, F11, F12, F22, F5, F9, etc.
    1. Stainless Steel FlangeOur stainless steel flange shows terrific corrosion resistance, and keep the original engineering design permanently. It applies to the pressure vessels, such like boiler, the pressure conveyance of petroleum and chemical media, and the pharmacy, metallurgy, machinery manufacture and food process.
    1. Special Steel FlangeOur special steel flange is made of the SA182 F51/F53/F60, Inconel 6625, 800H 904L, an so on special steel materials. By contrast, it has the high purity and uniformity, Ultrafine structure, high machining preciseness, and more stable mechanical properties over the normal steel flange.
