Processing method of socket pipe fittings and pipe fittings production standard

May 09, 2018

The socket pipe includes a straight tube section of a plastic winding wall tube with a slightly larger outer diameter of the plastic winding structure wall pipe connected by the inner diameter. The inner wall of the end of the straight pipe section is provided with a ring for inlaying the expansion rubber ring, and the sealing groove is embedded with the expansion rubber ring. A pipe connecting with a pipe with a socket. It is often used in cast iron pipe and acid resistant ceramic tube. Insert one tube into the other end of the tube, fill in the linen or asbestos rope in the gap, and then plug the glue (such as cement, acid resistant mud, etc.), and achieve the sealing purpose.

1. Performance of socket pipe fittings

The main material of socket pipe fittings is stainless steel, which is produced by stainless steel. Check the stainless steel before producing socket pipe fittings to ensure the quality of socket pipe fittings produced.

1, path: the diameter of the pipe fittings is DN15-DN1200, which is produced according to the size of the pipe. Otherwise the pipe fittings produced are not in accordance with the production scale, and the qualified guarantee can not be obtained.

2, wall thickness: the wall thickness of the pipe fittings is SCH5-SCH160, the wall thickness error of the tubes produced is not more than 5 mm, and there is no important difference in thickness. It ensures the same thickness of the pipe fittings produced, which is not conducive to damage in use and affects the function of the use.

3. Characteristics of socket pipe fittings

Anti anticorrosion. Acid alkali resistance. Long service life, reasonable price calculation, smooth surface, acid and alkali resistance, high temperature resistance, reasonable price calculation, beautiful appearance, strong texture and performance.

4, the use of socket pipe fittings: socket pipe fittings are mainly used in water, drink, beer, food, petroleum chemical, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproof treatment, pipe and so on, and show good use value in the field of use.

5, rolling method: generally do not use mandrel, suitable for thick walled tube inner rim.

Three. Leak detection method for pipe fittings

The basic principle of leakage flux detection is based on the high permeability of ferromagnetic material. The permeability of the elbow corrosion defect is far smaller than the permeability of the elbow. The elbow is magnetized under the applied magnetic field. When there is no defect in the elbow, most of the magnetic lines of force pass through the steel tube. At this time the magnetic line of force is evenly distributed; when the elbow is bent, the elbow is evenly distributed. When internal defects occur, the magnetic field lines are bent, and some magnetic lines of force leak out of the surface of the steel tube. The leakage flux detected on the surface of the magnetized elbow can be detected to determine whether the defect exists.
