Product Introduction

Single flange expansion joint is an important connecting equipment used in pipeline system, mainly used to absorb the length change of the pipeline caused by temperature changes, medium pressure fluctuations and other factors, so as to maintain the tightness and stability of the pipeline. It is composed of flanges, telescopic bodies and seals, etc., which adapt to the length change of the pipeline through the telescopic deformation of the telescopic body, and at the same time the seals form a tight seal between the flange and the telescopic body to prevent medium leakage.

How the product works

The working principle of the single flange expansion joint is to absorb the length change of the pipeline due to temperature changes, medium pressure fluctuations and other factors through the expansion and contraction deformation of the expansion body. When the pipe is subjected to a change in temperature or pressure, the expansion deformation will occur to adapt to the change in the length of the pipe. The seal creates a tight seal between the flange and the telescopic body, preventing media leakage, thus maintaining the normal operation and service life of the piping system.

Product application field

1.Construction: In the plumbing system of water supply, drainage, fire protection and other pipelines of buildings, single-flange expansion joints can effectively absorb the changes in pipe length caused by temperature difference and pressure changes to ensure the normal operation of the pipeline system.
2.Industry: In the pipeline system of petrochemical, electric power, metallurgy and other industries, the single flange expansion joint can withstand high temperature, high pressure and other harsh environments to ensure the stability and safety of the pipeline system.
3.Municipal field: In urban water supply, drainage, gas and other pipeline systems, single flange expansion joints can effectively prevent pipeline damage and leakage caused by factors such as temperature difference and ground subsidence.

Product Installation

1. Preparation: Before proceeding with the installation, the first thing to do is to inspect the joints and pipes to ensure that they are in good condition and to prepare the tools and equipment that need to be used.
2. Clean the pipe flange and installation area: Clean the pipe flange and installation area to ensure that there is no dirt, grease or other obstructions on the surface.
3. Installation and positioning: Place the single flange limit expansion joint on the pipe flange, and fix it to the flange of the pipe with bolts and nuts to ensure that the joint is correctly aligned with the pipe flange.
4. Adjust the angle and position: Adjust the installation position and angle of the joint according to the actual needs and the design requirements of the joint to ensure that it meets the design requirements of the pipeline system.
5. Bolt fastening: Use the correct bolts and washers according to the specifications to firmly fix the single flange limit expansion joint on the pipe flange to ensure that the bolt tightening force meets the requirements.
6. Regular inspection: After installation, regularly check the position and connection parts of the joints to ensure the firmness and correctness of the installation.
