What is the material of carbon steel elbow

In piping engineering, flanges are mainly used to connect pipes.Carbon steel elbow is an elbow made of carbon steel.When the flow rate is high, the pipe diameter is small, but the pressure drop value increases.Generally for the main sex noun, tee for pipe fittings, pipe connectors, used in the main pipe to branch pipe.But if the temperature rises just into the hot brittle zone, the metal will become less plastic.Whether casting flange or forging flange belongs to the common manufacturing method of flange. It depends on the strength requirements of the parts needed to be used. If the requirements are not high, you can also choose turning flange.You've probably seen the push machine, but it's actually very simple.

Seamless elbow is also called seamless steel pipe. Seamless elbow pipe fittings are divided into two kinds: hot rolling (extrusion) seamless elbow pipe fittings and cold drawing (rolling) seamless elbow pipe fittings because of its different manufacturing process.The most commonly used steel plate is carbon steel (20#), alloy steel and stainless steel, a total of 24 kinds of steel.Adjusting machine can not open the cooling system, and then turn on the shunt cone cooling duct, the upper mold core cooling duct, the lower mold core cooling duct, the wheel wheel and spoke junction cooling duct.Stainless steel tee for pipe fittings, pipe connectors.Stress free annealing, also known as low temperature annealing (or high temperature tempering), is mainly used to eliminate residual stress in castings, forgings, welding parts, hot rolled parts, cold drawing parts, etc.At the same time, the overall strength of pipe and elbow should also be considered.

1, because most of the pipe fittings are used for welding, in order to improve the welding quality, the end of the car into the groove, leaving a certain Angle, with a certain edge, this requirement is also strict, the thickness of the edge, the Angle of the number and the range of deviation are specified.The surface quality and mechanical properties are basically the same as the pipe.For ease of welding, the fittings are of the same type of steel as the pipes to be connected.

2, that is, all the pipe fittings should be surface treatment, the inner and outer surface of the oxide sheet by shot peening treatment spray, and then coated with anticorrosive paint.This is for export needs, moreover, in order to facilitate transportation in China to prevent corrosion and oxidation, both have to do this work.
