Carbon steel elbows are divided into several aspects

The advantages of the forming process of carbon steel elbow are mainly shown in the following aspects: simple blanking, convenient assembly and welding; Do not need tube blank as raw material; Short manufacturing cycle and low production cost.

In the production process of carbon steel elbows, a round shell can be cut into 4 90 ° elbows or 6 60 ° elbows or other elbows. This process is suitable for manufacturing any large size push elbows with the ratio of elbow middle diameter to elbow inner diameter greater than 1.5d. It is an ideal method for manufacturing large size push elbows at present. Alloy elbow don't need tube billet as a raw material in production engineering, can cut down the cost of pipe equipment and mould, machining alloy elbow billet for tablet or developable surface, thus cutting is simple, easy to guarantee accuracy, welding assembly is convenient, easy to control when processing raw material, the operation is simple, no complicated process, and welding and assembly is more convenient. Any large diameter and relatively thin wall thickness push elbow can be obtained. The material of this alloy elbow is special, and it does not need to add the raw material of tube blank, so it is easy to control during processing. Does not require any common equipment, especially suitable for field machining of alloy elbows. Therefore, short manufacturing cycle and low production cost are its big advantages.

Carbon steel elbow has the following advantages: health, light weight, good heat resistance, good corrosion resistance, good heat preservation, good impact resistance, long service life characteristics

Health: the material is completely composed of carbon and hydrogen without any toxic heavy metal salt stabilizer. The health performance of the material has been tested by various departments.

Light weight: the density of alloy elbow is 0.89-0.91g/cm, which is one tenth of steel pipe. Due to its light weight, the industry can greatly reduce transportation costs and installation of construction intensity.

Good heat resistance: when the working water temperature is 70 degrees, the softening temperature is 140 degrees.

Good corrosion resistance: in addition to a few hydrogenating agents, can resist the erosion of a variety of chemical media, with excellent acid resistance, alkali resistance, corrosion resistance, no rust, no corrosion, no electrochemical corrosion.

Good thermal insulation: due to the low thermal conductivity of the material, the thermal conductivity of 20 degrees Celsius is 0.21-0.24W/ MK, much smaller than the steel pipe (43-52W/ MK), purple steel pipe (333W/ MK), so the PP-R pipe has good thermal insulation.

High impact resistance: due to the different impact strength performance compared with other solid wall tube has significantly improved, its ring stiffness is equivalent to 1.3 times of solid wall.
