The range of butt weld flange use is determined according to different characteristics. They are mostly used in the case of moderate medium conditions, such as low pressure non-purifying compressed air and low pressure circulating water. Its advantage is that the price is cheaper. Butt weld flanges are suitable for connection of steel pipes whose nominal pressure does not exceed 2.5MPa. The sealing surface of butt weld flanges can be made into three types of smooth, concave and convex. Smooth butt weld flange application of the largest amount, the other two methods of butt weld flange is also common in use.

Butt Weld flange is not easily deformed, with well sealed, so they are widely used. They have the corresponding rigid and elastic requirements and a reasonable butt welding thin transition, welding seam from the joint surface distance, so the joint will not be affected by the welding temperature deformation. They have a more complex body structure, so they are suitable for pressure or temperature fluctuations in the pipeline or high temperature, high pressure and low temperature pipe, generally used for PN greater than 2.5MPa pipe and valve connections; also used to transport prices Expensive, flammable, explosive medium on the pipeline.

Butt Weld flanges are used for connecting flanges and pipes, including many types and models. They are mainly used in welding technology and perform well in service and performance. They have reasonable structure, high strength and rigidity, Withstand high temperature and pressure and repeated bending and temperature fluctuations, reliable sealing, butt flange designed for nominal pressure of 0.25 ~ 2.5MPa is with concave and convex sealing surface. The main application environment of butt weld flange should be appropriate, this need to be determined according to the specific circumstances to ensure the specific use of welded flange of the value and performance, withstand high temperature and pressure.
Butt weld flanges, especially for SAE butt weld flanges, are generally made by forgings or forging processes.

Stainless Steel Reducing Flanges tend to be durable and corrosion resistant in nature. Depending on the material used to produce the ASTM A182 SS reducing wn flange, the mechanical as well as physical properties and behaviour under different conditions will vary.
Advantages of an ASME B16.5 Reducing Flange is as follows -

  • ANSI B16.5 Reducing Flanges allows for the connection of two different sized pipes
  • reducing Flanges b16.5, are considered to be an easy as well as an inexpensive method of connection.
  • ASME B16.5 Reducing Flanges can be used to conserve water in many industries. Since the ASME B16.5 Reducing Flange is constructed from a single metal in our factory, there are no scope for porosity, which in turn makes the Carbon Steel Reducing Flange a leak free alternative.
  • Inconel reducing pipe Flanges are known for their resistant to acid

With the fore mentioned advantages, the ASTM A182 SS reducing wn flange is commonly used in sectors such as power plants as well as in industrial vessels. However, the buyer must check the changing line size to choose an apt Reducing Flange Dimensions that is well suited to his purpose or end use.

A collar is essentially used to couple a flange to a pipe. They are versatile and can be used in flange assemblies to form a compact system. When they are added to piping systems, the Plain Collar Flange offers a leak-proof finish, thus preventing the escape of gases or liquid by their tight seal. Typically they are used in systems that have connections with pressed flanges. Pressed flanges are popular in industries like Oil & Gas, Purification, Chemical as well as Petrochemical because they offer fitted connections. While using pressed flanges, one needs to make use of a sealing gasket for a snug fit. To optimize the connection between piping systems, and a pressed flange a sealing gasket is added between the two DIN 11864-2 Pressed Collar Flange. Once the bolts are tightened, the gasket ensures absorption of stress from the collars. As with most flanges, the material they are made from gives them their characteristics. The preference for Stainless Steel Collar Flange in both grades 304 and 316 is more because they offer better mechanical properties, and moderate to good resistance to corrosion. Though grade 316, exhibits better corrosion resistance behavior in comparison to grade 304.
