The integrity of flange connections is very important for conveying fluid piping systems. Whether it is the pipeline system transporting chemical medium (such as hydrocarbons) or the water supply pipeline, the leakage of the flange connection will cause serious environmental and economic effects, and may even bring huge potential safety hazards. If flanges are not

The alloy steel flange material has great strength, large tangential stress and large plastic deformation during cutting, resulting in large cutting force. In addition, the thermal conductivity of the material is very poor, which causes the cutting temperature to rise, and the high temperature is often concentrated in the narrow area near the cutting edge of the

Stainless steel pipe fittings belong to one kind of pipe fittings, it is made of stainless steel material so called stainless steel pipe fittings, it includes: stainless steel elbow, stainless steel tee, stainless steel tee, stainless steel four-way, stainless steel different diameter pipe, stainless steel pipe cap, according to the connection method can be divided into

Stainless steel pipe fittings are mainly used in aerospace and ordnance industries. One of the most important advantages of metal spinning process is that it can make integral seamless rotary hollow parts, which eliminates the defects of discontinuity, strength reduction, brittle cracking and tensile stress concentration related to welds. With the development of spinning technology, spinning process

Slip on flange is a flange that is connected to a container or pipe by fillet weld. It is an arbitrary flange. According to the degree of integrity of the connection between the flange ring and the straight cylinder section, the design is checked by the integral or loose flange respectively. Slip on flange not

When the two edges of the tube blank are heated to the welding temperature, the common metal grains are formed under the extrusion of the extrusion roll, which permeate and crystallize with each other, and finally form a solid weld. If the extrusion force of the weld is too small, the number of common crystals will

Use of heat preservation elbow and hot pressing elbow: Connect two pipes with the same or different nominal diameter to make the pipe bend at a certain angle. Classification of heat preservation elbows and hot pressing elbows: 1. Carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon lapping, ppc, etc. 2.

Now many people will come into contact with the flange, but do not know what kind of flange in the end is what kind of thing, flange appears in people’s lives everywhere, the following to elaborate on the use of carbon steel flanges and connections. Flange connection is the two pipes, fittings or equipment, first fixed in

Flat welded flange is not common in our daily life, but it plays a very important role, for some people who have just started to understand it should not be too much, in this article, to share with you. Flat welding flange can be divided into rotary forging, rotary forging, roll forging, cross wedge rolling, ring

The sealing failure of large flange sealing joint is mainly manifested in leakage. In pipeline systems and installations in various industries, the sealing failure of carbon steel flange joints can cause a large amount of waste of energy and raw materials. If the cost of labor and materials is any more serious, it will lead to equipment
