How to solve the defect of 180 degree stainless steel elbow?

180 degree stainless steel elbow is one of the commonly used pipe fittings,but it has some defects,today i’ll tell you how to solve the defect of 180 degree stainless steel elbow.

ASME B16.9 stainless steel 180 degree long radius elbows

Solution:

A stainless steel corrugated hose is installed at 1 / 3 of the inflation pipe, and a guide mechanism is installed at the front end of the argon charging device, which is rigidly connected with the front seal. When the guide mechanism of the argon filling device moves along the curvature of the elbow, the vertical center line of the front-end sealing sheet can achieve good sealing effect, while the stainless steel hose bends and drives the front-end sealing sheet to the designed sealing position.

The anti falling soft connection mechanism is installed in the inflation pipe. When the stainless steel corrugated hose falls off, the front-end guide mechanism and the sealing sheet can be taken out through the soft connection mechanism.

During the welding process, the paper burns about 10 mm before the arc, which greatly reduces the argon consumption and further improves the welding quality.
