Thick Wall Pipe Expansion Joints

Thick Wall Pipe Expansion Joints Brief Introduction

Thick wall pipe expansion joints are optimized according to GB/T16749-1997 standard, which effectively ensures the high safety performance of pressure pipelines when conveying various harmful, toxic, flammable and explosive media, and avoids leakage pollution that causes environmental pollution in the ocean, sky, factories, etc. Its product features are high temperature resistance, high pressure resistance, corrosion resistance, fatigue resistance, and wear resistance. Thick-walled compensators, also called thick-walled expansion joints, are a type of metal bellows, suitable for boiler pressure vessels, high-strength, small compensation shells, containers and pipeline compensation. Temperature range: -40~450℃

Thick Wall Pipe Expansion Joints Working Principle

The working principle of thick wall pipe expansion joints is based on the principle of elastic deformation. When the pipe, container or equipment expands due to temperature changes, the corrugations or folds inside the thick-wall expansion joint will elastically deform to absorb the stress generated by these deformations. When the temperature drops or the pipe shrinks, the thick-wall expansion joint will return to its original shape to maintain the stability of the system.

Thick Wall Pipe Expansion Joints Performance characteristics

The thick Wall Pipe Expansion Joints has two types: integral forming and welding forming. It is mainly used to compensate for the axial displacement of the equipment itself. It is mostly used for thermal compensation deformation of the container cylinder itself. The compensation amount is small, generally only 1 to 2 waves are needed. Main performance characteristics: thick wall, large rigidity, high strength.

Thick Wall Pipe Expansion Joints Application Scope

Commonly used at the outlet of pumps, tanks, compressors, turbines and other containers with high temperature, high pressure, or frequent vibration to ensure the safety and reliability of the system.Suitable for boiler pressure vessels, high-strength, small compensation shells, containers and pipeline compensation.
