International Children’s Day is scheduled for June 1 every year. In commemoration of the leditzer massacre on June 10, 1942 and all the children who died in the war all over the world, we oppose the maltreatment and poisoning of children, and safeguard the rights of children. In November 1949, the International Federation of democratic

The process analysis of the socket and the determination of the process plan are based on the geometrical shape and the process characteristic of the socket. Die structure design, especially the design of the die working parts, depends on the shape of the socket. The inner wall of the socket pipe fitting often produces certain corruption, and

Stainless steel flange is a disk-like part, in the pipeline engineering flange is mainly used for the connection of pipelines, in the need to connect the pipeline, each installation of a flange, low pressure pipe can use wire flange, more than 4 kilograms of pressure on the use of welding flange, two pieces of flange

The carbon steel flange according to the seal surface different has many kinds of classification, the flange seal surface form and the use environment has the direct relations, below the small plait to take everybody to understand each kind of different seal surface. 1. The whole plane of the sealing surface type (FF): More for the flat

Carbon steel elbow is a kind of elbow that can improve the temperature of warmth, which is often used in people’s daily life, which has been widely accepted and used. Carbon steel elbow universal use and construction, in the laying of the decoration and piping, it is very good to ensure the normal and unobstructed piping. Although

High-pressure flange is widely used, but its quality requirements are very high, the traditional high-pressure flange is the use of gasket (elliptical pad, octagonal pad, lens pad, etc.) of plastic deformation to achieve the sealing effect, connected to the pipe end, so that the pipe and pipe connected to the parts, flanges have holes, double

Stainless steel flange in processing, in addition to the multi-channel heat treatment process, also need to use the cutting process, the main tool is cutting blades, etc., but for stainless steel flange material cutting is not very simple, in the cutting to consider the hardness of stainless steel flange, and the resulting cutting is difficult

Stainless steel flange metal performance is good, and has a strong corrosion resistance, often used in steel structures, for example, stainless steel flange, stainless steel flange also become rust-proof steel flange, its metal surface is smooth, not easy with air oxidation, so often used in high-pressure water pipes and corrosion of the pressure pipe, here

Carbon steel elbow in accordance with the production process can be divided into: welding elbow, stamping elbow, casting elbow and so on. Valve testing machine Most gaskets are from non-metallic plate, or by the professional factory in accordance with the size of the production, its materials for asbestos rubber plate, asbestos Board, polyethylene board, and

The traditional high pressure flange has the following characteristics:   1. The high pressure flange is connected by bolts; 2. Its sealing principle is plastic deformation to achieve sealing effect; 3. The high-pressure flange is generally large in volume, so it is relatively difficult to install and position the high-pressure flange; 4. The bolts of
