Overview

Manufacturer of 304 stainless steel card sleeve joints, characterized by corrosion resistance, high pressure resistance, simple installation, and durability. The specification of the card sleeve connector consists of three parts: the connector body, the card sleeve, and the nut.

Product Details

Manufacturer of 304 stainless steel card sleeve jointIt has the characteristics of reliable connection, high pressure resistance, temperature resistance, good sealing and repeatability, easy installation and maintenance, and safe and reliable work. 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. The card sleeve joint has the characteristics of corrosion resistance, high pressure resistance, simple installation, and durability.

● Installation

1. Cut off seamless steel pipes of appropriate length and remove burrs at the ends. The end face of the pipe should be perpendicular to the axis, with an angle tolerance of no more than 0.5 °. If the pipe needs to be bent, the length of the straight section from the end face of the pipe to the bent part must not be less than three times the length of the nut.

Two nuts and clamps are fitted onto the seamless steel pipe. Pay attention to the direction of the nut and sleeve, and do not install them upside down.

Apply lubricating oil to the threads and sleeve of the pre assembled joint body, insert the pipe into the joint body (make sure the pipe is inserted to the bottom), and tighten the nut by hand.

Tighten the nut until the sleeve grips the pipe, and this turning point can be felt by increasing the tightening torque (pressure point).

After reaching the pressure point, tighten the compression nut by 1/2 turn.

6. Remove the pre assembled joint body and check the embedding of the blade edge of the card sleeve. The visible protrusion must fill the space on the end face of the card sleeve. The card sleeve can rotate slightly, but cannot move axially.

7. For final installation, apply lubricating oil to the threads of the joint body during actual installation, tighten the nuts and tighten them until the noticeable tightening force increases Then tighten another 1/2 turn to complete the installation.

Precautions

（1） When connecting pipelines, the pipes should have sufficient deformation allowance to avoid being subjected to tensile forces.

（2） When connecting pipelines, avoid subjecting them to lateral forces, as excessive lateral forces can cause poor sealing.

（3） When connecting pipelines, they should be done in one go to avoid multiple disassembly, otherwise it will also deteriorate the sealing performance.

Manufacturer of 304 stainless steel card sleeve jointThe working principle is to insert the steel pipe into the sleeve, lock it with the sleeve nut, resist the 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.

Card sleeve connector, the specification of the card sleeve connector consists of three parts: connector body, card sleeve, and 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.
