Operation of butt welding elbow before fabrication

Operation of butt welding elbow before fabrication and installation

Butt-welding elbows are steel hot pressing or forging shaped elbow pipe fittings. Butt-welding elbows are directly welded together with steel pipes in the manufacturing and connection forming process, not socket, not wire buckle, not groove. It can be straight seam elbows or butt-welding elbows.

Butt-welding elbow manufacturers mainly produce elbow, tee, size, cap and other head sealing pipe fittings.More than the company in the production of pipe fittings mainly USES the advanced equipment and technology in the production of custom fitting models, the company to the user, quality, reputation, services for the purpose, with strict management mechanism, strengthen the ability to support of technology, in an effort to the pursuit of quality, create brilliant performance as the goal, sincerely hope to cooperate with customers both at home and abroad, achieve win-win situation.

Before installing butt welding elbows, pipe segments should be measured and numbered one by one. It is advisable to select pipe segment groups with small diameter difference to butt butt.When joining pipes in the middle of the ground, 14CM*14CM sleepers should be used to pad the pipes flat instead of iron steel pipes, and the rolling of the pipes should be reduced as far as possible to avoid damaging the external corrosion protection of the pipes.

Please check the inner and outer anticorrosion layer of the pipe before running the pipe, and then run the pipe after passing the test.When the pipe section is composed of the pipe section, the length of the pipe section and the lifting distance should be based on the diameter of the pipe, the thickness of the wall, the material type of the outer anticorrosion layer and the pipe.Clean the dirt in the pipe, and polish the edge of the pipe mouth and both sides of the welding joint to expose the metallic luster and make the groove.The above briefly introduces the production process of butt-welding elbow pipe fittings.Welcome customers who need to welding elbow pipe fittings to inquire and order!

Seamless elbow also has very good heat resistance and heat preservation.Seamless elbow it has very good stability, it itself is very sanitary, without any toxic properties.Seamless elbow its weight is very light, so that it can greatly facilitate processing and installation, but also can reduce transportation costs.Seamless elbow its corrosion resistance is very good, can resist the erosion of many kinds of chemical substances, but also will not breed rust and so on.The service life is very long, but also will not easily fade.

Carbon steel seamless elbow is divided according to the material, the commonly used material is: Q235B/20#/ 20G/ Q345B/20G/ 16MN /ASTM A234, also known as stamping elbow and welding elbow.

Seamless elbow is an elbow made of excellent seamless pipe. According to the wall thickness of different steel pipes, different elbow forming processes are selected. The general forming processes are hot pushing, stamping, extrusion, etc.Seamless elbow has good health, light weight, good heat resistance, good corrosion resistance, good insulation, good resistance to impact performance, long service life, and so on many advantages, widely used in chemical industry, construction, water supply, water drainage, oil, light and heavy industry, freezing, sanitary, plumbing, fire protection, electric power, aerospace, shipbuilding and other basic engineering.
