The insulating flange is a general term for pipe flange joints that have both the sealing performance required for buried steel pipelines and the electrical insulation performance required for galvanic corrosion protection projects. It includes a pair of steel flanges, insulating seals between the two flanges, flange fasteners and fastener insulating parts, and a pair […]

What are the high requirements of pressure vessels for flanges?
As a pressure vessel, it must have the following characteristics, such as high-temperature resistance, corrosion resistance, leakage prevention, and easy repair. However, the flange interface of a pressure vessel is usually the only channel for handling materials and the interface for docking other facilities. The tightness of the butt joint seal of the pressure vessel […]
Processing technology of rolled flange
The definition of type flange is mainly based on the size of the flange. The usual form of expression is the coiled flange. The disadvantages are determined according to different characteristics. The advantage of non-purified compressed air and low-pressure circulating water is that the price is relatively cheap. Here I would like to share with […]
304 stainless steel flange use
Stainless steel flanges generally have insufficient load-bearing strength, and cannot be used on all high-pressure pipelines until the appearance of neck-welded flanges improves the load-bearing strength of the flange. so that various high-pressure pipelines can be used. Stainless steel high-pressure flanges are one of the pipe fittings, which have been used in various fields now. […]
Why flat welding flange can save space
The flat welding flange is a concave platform with an inner hole that is slightly larger than the outer diameter of the pipe, and the pipe is inserted into it and welded. The flat welding flange can greatly reduce weight and save space, and can also ensure that the joint does not leak and has […]
What are the materials of carbon steel flanges?
The butt welding flange is not easy to deform, has good sealing, and is widely used. It has corresponding rigidity and elasticity requirements and reasonable butt welding thinning transition. The distance between the welding port and the joint surface is large, and the joint surface is free from welding temperature deformation. It adopts a relatively […]
Where are flanges applied?
The application of flanges plays an important role in many aspects, including various sectors of the national economy such as the petrochemical industry, energy industry, scientific research and military industry. However, in the reactor of the refinery, the production environment of the flange is very harsh, and the performance of the flange must be excellent […]
Carbon steel flange
Carbon steel flanges, that is, flanges or end flange connectors whose body material is carbon steel. Flanges containing carbon steel are called carbon steel flanges. Common materials are cast carbon steel grade WCB, forging A105, or Q235B, A3, 10#, #20 steel, 16 manganese, 45 steel, Q345B, etc. Usually, to prevent rust, the surface of the […]
Take your in-depth understanding of flange
What is a flange? Flanges are cast or forged steel products used to connect pipes with other mechanical equipment. In the oil and gas industry, forged steel flanges are favored for their inherent strength and durability. Flange size The critical dimensions of pipe flanges are: Nominal size (that is, the aperture of the flange to […]
History of flanged pipes
Most people associate flanged pipes with the oil industry. However, they offer a lot more functionality than you may realize. Another thing about them is that they have been around for a while. In fact, humans have a long history of using flanged pipes as a means of transportation to meet various needs. Here’s what […]
