Double card set of joint connected with reliable, high voltage capability, high temperature, good sealing and repeatability, installation and maintenance convenient and safe reliable.
The working principle of the double card sleeve joint is to insert the steel pipe into the clamping sleeve, and the clamping sleeve is used for locking the locking sleeve nut. It is connected with the steel pipe does not need welding, is conducive to fire, explosion and aerial work, and can eliminate the disadvantages caused by welding. So it is a kind of more advanced connecting parts in the pipeline of oil refining, chemical industry, petroleum, natural gas, food, pharmaceutical, instrument and meter. Suitable for oil, gas, water and other pipeline connection.

Card sleeve joint overview:
The sleeve type pipe joint is composed of three parts: a joint body, a clamping sleeve and a nut. When the card sleeve and the nut is sheathed on the steel pipe is inserted into the joint body, tighten the nut, set at the front end of the outer and the joint body cone laminating card, inside edge evenly bite seamless steel pipe, forming effective sealing.
