The sleeve type pipe joint consists of three parts: the joint body, the sleeve, and the nut. When the card sleeve and nut sleeve are inserted into the joint body on the steel pipe and the nut is tightened, the outer side of the front end of the card sleeve is in contact with the conical surface of the joint body, and the inner blade is evenly bitten into the seamless steel pipe, forming an effective seal. It is easy to install and has high pressure resistance, making it widely used.

advantage

The card sleeve connector has the characteristics of reliable connection, high pressure resistance, temperature resistance, good sealing and repeatability, easy installation and maintenance, and safe and reliable operation.

Working principle

The working principle of the card sleeve joint is to insert the steel pipe into the card sleeve, lock it with the card sleeve nut, resist the card sleeve, and cut into the pipe to seal it. It does not require welding when connected to steel pipes, which is beneficial for fire prevention, explosion prevention, and high-altitude operations, and can eliminate the drawbacks caused by careless welding. Therefore, it is a relatively advanced connecting component in the pipeline of automatic control devices in refining, chemical, petroleum, natural gas, food, pharmaceutical, instrumentation and other systems. Suitable for connecting pipelines for media such as oil, gas, and water.
