Industrial Flange

    1. Slip On Weld Flange
    2. Slip On Weld Flange
      Slip on weld flange is probably the most widely used flanges and is ideal for connection of steel pipes with nominal pressure less than 2.5MPa. There are several mounting holes around the perimeter and two flanges are bolted together with a gasket in between them. American series: Flat Face(FF), Raised Face(RF), Groove(G), Male and Female Face(MFM), Ring Joint(RJ)
    1. Weld Neck Pipe Flange
    2. Weld Neck Pipe Flange
      A weld neck flange is an industrial flange that has a long tapered hub. Our weld neck flanges are widely used for pipelines which are subject to high pressure and extreme fluctuations of temperature.

    1. Plate Weld Flange
    2. Plate Weld Flange
      A plate weld flange is a flat, circular disk with several holes around the perimeter, used to join a variety of elements. Flanges are frequently used in pairs. They are bolted together with a gasket in between them. Due to its low cost and ease of use, plate weld flange is widely used in fuel and water pipelines.
    1. Blind Pipe Flange
    2. Blind Pipe Flange
      A blind flange is a plate that has no opening to allow fluid to pass through. Thus, it can be used to block off the flow of liquid through a pipeline or to create a stop. The blind flange is typically used for pipeline maintenance or repair tasks. American series: Flat Face(FF), Raised Face(RF), Groove(G), Male and Female Face(MFM), Ring Joint(RJ)

An industrial flange is an external or internal rim primarily used for joining system parts, such as pipes. As an experienced industrial flange manufacturer in China, we at SHENGSENYUAN provide a vast range of flanges, including slip on weld flange, weld neck flange, plate weld flange and blind flange, which are used in a variety of applications. For example, our slip on flange is ideal for low pressure applications, our weld neck flange is suitable for high pressure, low temperature and high temperature applications, and our blind flange is used to block off a pipe or create a stop. To accommodate every customer's requirements, we make our flanges in a variety of materials, such as carbon steel, alloy steel and stainless steel. With the features of being reliable, economical and long lasting, our products are very popular with customers around the world.

To help customers have a general understanding of industrial flanges, here we give some useful information as follows Types
There are many kinds of industrial flanges available, which can be classified as follows
1. According to their designs, flanges can be classified into integral flange, lap joint flange and threaded flange etc. The integral flange is further classified into flat weld flange and weld neck flange.
2. According to their facing types, flanges can be divided into flat face flange, male and female face flange, tongue and groove face flange, etc.
