Flange is also called flange plate. Flange is the part connecting the pipe to the pipe, which is connected to the pipe end; it is also useful for the flange on the equipment inlet and outlet, which is used for the connection between two equipment, such as the reducer flange. Flange connection or flange joint

Forged flange is one of the products with the best mechanical properties in flange products. Its raw material is generally tube blank, and then it is cut and hammered continuously to eliminate segregation, looseness and other defects in ingot. The price and mechanical properties are one grade higher than that of common cast flange. Flange

The shape and size of the casting blank are accurate, the machining amount is small and the cost is low, but there are casting defects (porosity, crack and inclusion); the internal structure streamline of the casting is poor (if it is a cutting part, the streamline is worse); The advantages of the casting are that

FIGURE 8 BLIND FLANGE is a solid plate or common steel plate used to block the pipeline equipment at the connection of two flanges. The purpose is to test the pressure, leak and block the pipeline of pipeline equipment. The product pipe size range is & frac12; “to 96”, and the flange grade range is

Production reached a record high. From January to June 2013, China’s total production of crude steel was 390 million tons, up 7.4% year on year, 5.6 percentage points higher than that of the same period last year. In the first six months, the average daily output of crude steel was 2.154 million tons, equivalent to

There are some points of SEAMLESS PIPE welding: 1. Adopt the power supply with vertical external characteristics, and adopt the positive polarity (welding wire is connected to the negative electrode) when DC. 2. It is generally suitable for the welding of thin plates under 6mm, with the characteristics of beautiful weld forming and small welding deformation.

Stainless steel pipe is a kind of hollow long cylindrical steel. Its application scope is used as the pipeline for conveying fluid, mainly used in petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and other industrial transmission pipelines and mechanical structural components. The stainless steel pipe is made of the billets of acid

There are two systems in the international pipe flange standards, namely the European pipe flange system represented by DIN (including the former Soviet Union) and the American pipe flange system represented by ANSI. In addition, there are JIS pipe flanges in Japan, but they are generally only used for public works in petrochemical plants, and

How to determine the flange size? 1.First, judge the flange type. Common flange types include flat welding flange,Butt Welded Fitting, SOCKET WELD/SW FLANGE, plate welding flange and ring loose flange. 2.Second, judge the flange end form, mainly RF, concave, convex, RJ torus. Tenon groove face 3.After judging the flange type, the main measured data are

LAP JOINT/LJ FLANGE is also called flange. It’s a part of the tube that connects with the tube. Connect to pipe end. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected. The flange is sealed with gasket. Flange pipe fittings refers to the fittings with flange
