Quick Response Code
Flange, also known as flange plate or flaunching, is used to connect pipes on the end of the pipes. Two pipes, fittings or equipment are mounted with a flange apiece. A flange pad will be put between these two flanges, which are fastened together with bolts. There are also pipes and equipment which come with flanges originally, thus leading to easy connection. Pipes connected with flanges can be disassembled again.
    1. Integral Flange

      The integral Flange (IF) is designed for connection of pipes. As one of hubbed welding neck steel pipe flanges, it can be made of different kinds of steel including carbon steel, stainless steel, alloy steel, etc.

    1. Slip-on Flange

      Compared with common slip-on-welding flange, hubbed slip-on flange has a short neck, which increases the strength and loading capacity of the flange. Therefore, it can be used on pipelines with higher pressure.

    1. Plate Flange

      Plate flange features high accessibility of its raw materials, easy manufacturing, low cost and good comprehensive performance.

    1. Threaded Flange

      Threaded flange has its inner bore surface designed as tubular thread, which matches with threaded pipe to achieve connection. Therefore, no welding is required.

    1. Socket Welding Flange

      Our socket welding flange is designed for pipelines with small diameter and high working pressure. Generally, the diameter is not greater than 40mm and the working pressure shouldn’t exceed 10.0Mpa.

    1. Blind Flange

      The flange is widely used in many areas such as power generation plant, petroleum industry, natural gas system, chemical industry, shipbuilding industry, heating system, paper-making industry, metallurgy industry, etc.

    1. Loose Flange

      In terms of connection mode between flange and pipe, flanges falls into five basic categories which are slip-on welding flange, welding neck flange, threaded flange, socket welding flange and loose flange. Loose flange is a combination of two kinds of flanges.

    1. Orifice Flange

      Installed in a closed pipeline, orifice flange is used to test the flow rate of fluid, gas and steam just like a throttling gear. Standard orifice plate is a metal plate with a round hole. Round-hole wall is perpendicular to the front face of orifice plate.

    1. Spectacle Flange

      Spectacle flange is made up with two metal discs which are attached to each other by a small section of steel. Its shape is similar to a pair of glasses or "spectacles".

    1. Lap Joint Flange

      Lap joint flange is similar to hubbed slip-on welding flange, while the difference is that it has a stud end at the intersection between the inner bore and the flange facing, which is used to accommodate the flange pad.

    1. Square Flange

      Non-standard flange is designed used for sealing and fastening. It is extensively applied in aerospace industry, petroleum industry and chemical industry.

    1. Pipe Elbow

      As a famous manufacturer of fittings, Hebei Zhouji Heavy Industries Co., Ltd. owns cutting-edge techniques and advanced production equipment, which include pushing machine, heating and bending machine, cold pressing machine as well as welding machine.

    1. Pipe Tee

      As a type of fittings, pipe tee comes into two shapes which are T-shapes and Y-shaped. It is usually installed at the intersection point of three pipelines. Our company provides various T-shaped tees, which include straight type and reducing type.

    1. Pipe Cross

      As a type of fittings, pipe cross is usually installed at the intersection point of four pipelines. Common cross can be divided into straight type and reducing type. Most crosses on current market are made through welding two tees together and rubbing off the welding joint.

    1. Pipe Reducer

      As one type of industrial fittings, reducing pipe is mainly used for connection between two pipelines with different diameters. Generally, pipe reducers can be divided into concentric reducer and eccentric reducer.

    1. Pipe End Cap

      Pipe cap is usually welded onto the end of a pipeline or screwed into the external thread on a pipe end to block up the pipe. Generally, it serves as a protection device for pipe ends.

    1. Stub End

      During flanging process, the workblank margin usually is not deformation zone because it is restricted by blank holder force and the ratio between the width of the margin and bore diameter is pretty large. The deformed wall serves as force transferring area.

    1. Socket Weld Fittings

      As a professional manufacturer in China, Hebei Zhouji Heavy Industries Co., Ltd. provide all kinds of socket welding fittings, which are mainly applied for connection in high-pressure pipelines.

    1. Threaded Fittings

      The product is widely used in many areas such as power generation plant, petroleum industry, natural gas system, chemical industry, shipbuilding industry, heating system, paper-making industry, metallurgy industry, etc.

    1. Swage Nipple

      The product is widely used in many areas such as power generation plant, petroleum industry, natural gas system, chemical industry, shipbuilding industry, heating system, paper-making industry, metallurgy industry, etc.
