Carbon steel high-pressure butt welding flange Executive standard: GB/T13402-2010 Specification size: 26 Pressure rating: Class300~Class900 Connection form: neck welding, single-sided bolt fastening Brief introduction of high-pressure butt welding flange High-pressure butt-welding flanges generally refer to butt-welding flanges or flanges that can withstand a relatively high-pressure level, because only neck-welding flanges can be applied to high-pressure […]

1. What is a flange? 1.1 Definition: Flange is a kind of pipe connection, used to connect two pipes, or connect pipes and equipment, making it a whole, with good sealing and easy disassembly. 1.2 Principle: The flange uses bolts as a means of transferring load, and generates pressure through the gasket between the two […]

Understanding stainless steel flanges: characteristics, classification and application range Stainless steel flange is a flange used to connect pipes and pipe fittings. Due to its good corrosion resistance, it is widely used in the chemical industry, oil and gas, water treatment, food and beverage and other industries. This article will focus on the characteristics, classification […]

Flanges are commonly used in piping systems to connect pipes, valves, pumps, and other equipment. They are typically made of metal, such as carbon steel, or stainless steel. Here are the general steps for manufacturing flanges: Raw material selection: The material for the flanges is selected based on the requirements of the application, such as […]

The two bolt sealing surfaces compress the flange gasket and seal against each other Since the advantage of non-standard flange seal is that it is convenient to inspect nuclear power plants, it has its supporters, especially when adopting a new sealing structure. The flat welding flange is a flange that is directly welded to the […]

First of all, we need to know what is a butt welding flange and a flat welding flange. The main differences between the two flanges are as follows: 1. Different forms of welds: The welds of flat welding cannot be detected by radiographs, but the welds of butt welding can be. The welding seam between […]

Classified according to the function and structural characteristics of the flange Flange is an important pipe fitting, which can fix pipes and equipment, has a certain strength, and can resist mechanical vibration of pipe fittings. They are widely used in petroleum, petrochemical, metallurgy, thermal power, nuclear power and other fields, and can connect several pipe […]

There are many types of high-pressure alloy flange Very short joints are called pairs of wires; wire plugs, high-pressure alloy flange classification: There are many types of high-pressure alloy flange flanges, which ensure that they can be managed and used in different ways and methods. There are many types of high-pressure alloy flange Coiled flanges […]

Forged flange connections are widely used Process: In fact, it is precision model forging, sometimes called precision pressing or embossing. Putting the forging that has been model forged into a precision die groove and applying pressure to make it produce slight deformation, so as to obtain high-precision size and smooth surface forgings. The neck flange […]

Characteristics of stainless steel flanges The stainless steel flange is characterized by fast welding speed and good weld shape. Stainless steel (stainless acid-resistant steel) flange is a disc-shaped part, which is more common in pipeline engineering, and flanges are used in pairs. In pipeline manufacturing, Flanges are mainly used for the link of pipelines. In […]
