Professional China Pipeline Compensation - Carbon Steel Seamless Bw Fittings Elbow 90 Deg – Xinqi

Seamless elbow is a kind of pipe fitting used for pipe turning. Among all the pipe fittings commonly used in the pipe system, the proportion is the largest, about 80%. Generally, different forming processes are selected for elbows with different materials and wall thicknesses. The commonly used seamless elbow forming processes of manufacturers include hot pushing, stamping, extrusion, etc

Seamless Elbow Classification

Seamless elbow is also called seamless steel pipe elbow. Due to different manufacturing processes, seamless elbow fittings can be divided into hot extruded seamless elbow fittings and cold extruded seamless elbow fittings.
Executive standards: GB/T12459-2017, GB/T13401-2017

Forming Method of Seamless Elbow

1. Forging method: stretch the end or part of the pipe with a swaging machine to reduce the outer diameter. The commonly used swaging machines are rotary, connecting rod and roller.
2. Rolling method: generally no mandrel is used, and it is suitable for the inner circular edge of thick wall pipe. The core is placed in the pipe, and the periphery is pushed with a roller for processing the round edge.
3. Stamping method: expand the pipe end to the required size and shape with a tapered core on the punch.
4. Bending forming method: there are three commonly used methods, one is called stretching method, the other is called stamping method, and the third is roller method, which has 3-4 rollers, two fixed rollers, and one adjustment roller. Adjust the fixed roller pitch. The finished pipe fittings are bent.
5. Bulging method: one is to place rubber in the tube and compress it with a punch to make the tube bulge into shape; The other method is hydraulic bulge forming. Fill the middle of the pipe with liquid, and the liquid pressure will bulge the pipe into the desired shape. This method is mostly used in the production of corrugated pipes.

Summary of Advantages

Hygienic, non-toxic, light weight, good heat resistance, good corrosion resistance, good thermal insulation, good impact resistance, and long service life.

1. Hygienic and non-toxic: the material is completely composed of carbon and hydrogen, without adding any toxic heavy metal salt stabilizer, and the hygienic performance of the material has been tested by the national authoritative department.
2. Light weight: the density of stamping elbow is 0.89-0.91g/cm, which is only one tenth of that of steel pipe. Because of its light weight, it can greatly reduce the transportation cost and the construction intensity of installation.
3. Good heat resistance: when the working water temperature is 70 ℃, the softening temperature is 140 ℃.
4. Good corrosion resistance: except for a few hydrogenating agents, it can resist the corrosion of various chemical media, and has excellent acid, alkali, corrosion resistance, no rust, no corrosion, no bacteria, no electrochemical corrosion.
5. High impact resistance: because the unique impact strength performance is significantly improved compared with other solid wall pipes, its ring stiffness is 1.3 times of the solid wall.
6. Long service life: under the rated service temperature and pressure, the pipe has a service life of more than 50 years, and is UV and radiation resistant, so that the product will never fade.
