General ships require thicker seamless steel pipes for bilge water pipes, deck washing pipes, air pipes, measuring pipes, injection pipes, sanitary water pipes, sea water pipes, fire fighting pipes and foam pipes The direction of the pipe fittings is the pipe elbows, and usually the seamless welding elbows are also used. The commonly used elbows are 45-degree angle elbows, 90-degree angle elbows and 180-degree angle elbows. Reasonable selective welding is performed according to the angle of the elbow direction.

Seamless elbow forming method

1. Forging method: the end or part of the tube is extruded with a forging machine to reduce the outer diameter

, Commonly used forging machines are rotary, link type, roller type.

2. Rolling method: Generally, no mandrel is used, which is suitable for the inner rounded edges of thick-walled pipes. A core is placed in the tube, and the periphery is pressed by a roller for round edge processing.

3. Punching method: Use a tapered core to expand the pipe end to the required size and shape on the punch.

4. Bending forming method: There are three methods more commonly used, one method is called stretching method, the other method is called stamping method, and the third roller method has 3-4 rollers, two fixed rollers, one adjustment roller, adjustment With fixed roller pitch, the finished pipe is bent.

5. Bulging method: one is to place rubber in the tube, and compress with a punch above to make the tube protrude; the other method is to use hydraulic inflation to form a liquid in the middle of the tube. Shape, most of the production of bellows uses this method
