Elbow In the pipeline system, the elbow is a pipe fitting that changes the direction of the pipeline. According to the angle, there are three kinds of 45° and 90°180° which are more commonly used. In addition, according to engineering needs, it also includes other abnormal angle elbows such as 60°.

The elbow is a kind of pipe fitting used at the turn of the pipeline. Among all the pipe fittings used in the piping system, the proportion is relatively large, about 80%. Generally, different forming processes are selected for elbows of different materials or wall thickness. The commonly used seamless elbow forming processes in manufacturing plants include hot pushing, stamping, and extrusion. So do you know what its hot forming process is? Let's follow the editor of Elbow for water treatment to have a simple understanding!

In pipeline systems, elbows are fittings that change the direction of the pipeline. According to angles, there are three most commonly used types: 45 ° and 90 ° and 180 °. In addition, according to engineering needs, there are also other abnormal angle elbows such as 60 °. The materials of elbows include cast iron, stainless steel, alloy steel, malleable cast iron, carbon steel, non-ferrous metals, and plastics. The methods of connecting to pipes include direct welding (the most commonly used method), flange connection, hot melt connection, electric melt connection, threaded connection, and socket connection. According to production processes, it can be divided into: welded elbows, stamped elbows, push made elbows, cast elbows, butt welded elbows, etc. Other names: 90 degree elbow, right angle bend, etc.

Tubing is mainly used to connect drill collars and drill bits and transmit drilling power; A casing is a steel pipe used to support the walls of oil and gas wells, ensuring the normal operation of the entire well during the drilling process and after completion.

High pressure boiler pipes are used for heating surface pipes of low and medium pressure boilers (with a working pressure generally not exceeding 5.88Mpa and a working temperature below 450 ℃); Used for heating surface pipes, economizers, superheaters, reheaters, petrochemical industry pipes, etc. of high-pressure boilers (with working pressure generally above 9.8Mpa and working temperature between 450C and 650 ℃).

A concentric reducer is a type of pipe that is directly welded to a steel pipe. The main manufacturing standards for concentric reducers are generally GB/T12459, GB/T13401, ASME B16.9, SH3408, SH3409, HG/T21635, HG/T21631, and SY/T0510. Corresponding to the concentric reducer, there are also eccentric reducers made of carbon steel, alloy steel, and stainless steel.

Hydraulic support pipes are made of high-quality carbon structural steel with appropriate addition of one or several alloy elements to improve the strength, toughness, and hardenability of the steel. After being made, this type of steel usually needs to undergo heat treatment such as quenching and tempering, chemical heat treatment, and surface quenching.

Brief introduction of PZ43H plum blossom knife gate valve: The opening and closing part of the knife gate valve is the gate, and the movement direction of the gate is perpendicular to the direction of the fluid. The knife gate valve can only be fully opened and fully closed, and cannot be adjusted or throttled. The gate has two sealing surfaces. The two sealing surfaces of the most commonly used model gate valve form a wedge. The wedge angle varies with valve parameters, usually 50.

Aluminum alloy characteristic ability of high temperature butterfly valve, apply pressure range is higher also, nominal valve size is big, the body is made of carbon steel, the valve plate seal aluminum ring is used to replace the rubber ring, apply to the hvac, central air conditioning, fluctuation of complete sets of equipment, lack of application in the: water, gas, oil, chemical industry, metallurgy, energy, shipbuilding, electric power, petroleum, water treatment, construction and other industries.
