Carbon steel elbow is resistant to air, steam, water and other weak corrosive media and acid, alkali, salt and other corrosive corrosive medium steel, also known as stainless acid resistant steel. In the power, mine, metallurgy and other industries of carbon steel, the delivery and output of materials are transported by close range and high pressure. The

In twenty-first Century, large flange is one of the main equipment in chemical and oil refining field. The carbon steel flange interface of pressure vessel is a necessary channel for huff and puff material, and is the interface for docking other facilities. The tightness of the sealing interface of the pressure vessel is guaranteed by every flange

When the flange is in use due to improper flange connection or excessive leaking in use, users do not panic. First of all, to check the leak location, the leakage area is usually very small due to the small gap between the stainless steel flange joints, so it is impossible to seal the leak by sealing the gap.

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.
