Overview

Attention to the supply of 304 stainless steel card sleeve joints: When connecting pipelines, the pipes should have sufficient deformation allowance to avoid being subjected to tensile forces. It should be avoided from being subjected to lateral forces, as excessive lateral forces can cause poor sealing.

Product Details

Supply of 304 stainless steel card sleeve connectorsThe specification consists of three parts: connector body, 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.

　　
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 reliable connecting component in the piping 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.

Supply of 304 stainless steel card sleeve connectorsReason for leakage
The pipe is not fully inserted.
The two nuts are not tightened.
3. Scratches on the surface of the pipe or the pipe is not round.
4 pipes are too hard.

Technical preparation before installation

Before connecting the card sleeve of the hydraulic system of the equipment, check the parameters and technical information first, and then prepare the equipment.

Installation of sleeve type connectors

The card sleeve joint equipment is an important link. If the equipment will affect the reliability of the seal, then you can first perform a trial installation on the small diameter joint on the vise, usually requiring a pre installer.

check

Disassemble the pipe to check if the equipment meets the requirements: there should be uniform and fine protrusions on the pipe at the end of the sleeve. The card sleeve cannot slide back and forth, but should have slight rotation.

All card sleeve connectors can be reinstalled multiple times, but it is important to ensure that the parts are undamaged and clean.

1. Insert the pipe into the joint body until the sleeve fits snugly against the conical surface of the joint body, and tighten the nut by hand.

2. Tighten the nut with a wrench until the tightening torque increases sharply, then tighten it by 1/4 to 1/2 turn.

Reasons for leakage

1. The pipe is not tightly inserted.

2. The nut is not tightened.
