What is the cause of flange leakage? 1. Reason for flange leakage: wrong mouth The staggered seam means that the pipe and the flange are vertical, but the two flanges are not concentric, and flanges are not concentric, so the surrounding bolts cannot freely penetrate the bolt holes. There is no other way, only reaming […]

The characteristics and sealing principle of flat welding flange
Flat welding flanges refer to flanges that are connected to vessels or pipes by fillet welding. It can be any flange. Check the integral flange or loose flange respectively according to the degree of integrity of the flange ring and straight cylinder section at the time of design. The ring of the flat welding flange […]
Advantages of high-pressure flanges
1. Sealing method: The core of the high-pressure self-tightening flange is a precise, new metal-to-metal seal, that is, the seal is formed by the elastic deformation of the sealing lip (T-arm) of the sealing ring, which is a hard seal; The combination of tendons and bones of the ferrule, the ferrule, and the sealing ring […]
Calculation Method of Flange Installation
The flange is a kind of detachable connection that can maintain a sealing effect within a certain pressure range. The working condition of the flange is composed of a pair of flanges, several bolts, nuts, a gasket and a washer. Under the tensioning action of the bolt, the flange compresses the gasket between the compression […]
Knowledge of butt welding flange
Butt welding flange refers to a flange with a neck and a round pipe transition and connected to the pipe by butt welding, which is a kind of pipe fittings. The advantages of butt welding flanges are anti-corrosion, acid and alkali resistance, long service life, etc., and the price is reasonable, the surface is smooth, […]

Weld Neck Flange
Weld neck flange are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for flanges, the standard height is 1/16″ for weld neck flanges fewer than 400#. For weld neck flanges of 400# and up, the standard flange raised face height is 1/4″. DESCRIPTION OF WELD NECK […]
Comparison table of stainless steel brands of various countries
stainless steel brands In order to solve the cumbersome and difficult-to-remember stainless steel grades, improve the practicability of the brand representation, and contrast with the international standard grades, China has formulated the “Universal Code System for Steel and Alloy Grades”, such as 06Cr19Ni10, corresponding to 304. Different grades of stainless steel have different ingredients, but […]
Cast and Forged Flanges
Cast and Forged Flanges For casting flanges, the shape and size of the blank are accurate, the processing volume is small, and the cost is low, but there are casting defects (porosity, cracks, inclusions); the internal organization of the casting is less streamlined (if it is a cutting part, the streamlined shape is even worse); […]
