Ceramic lined pipe

Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.

Expansion joints

Expansion joints are designed to safely absorb the movement in pipework systems due to heat-induced expansion and contraction of pipework.

Without them, pipes would not be able to withstand the forces exerted upon them and entire pipework systems would fail. When correctly selected and installed expansion joints act to prolong the service life of the pipework system and reduce the risk of downtime and for additional maintenance and repair.

How do they work?

Expansion joints - sometimes called expansion bellows, flexible joints or Expansion joint - are devices that comprise of a flexible element known as the bellows membrane that is fitted to end connections that are best suited to the pipework they are to be installed in.

What industries use expansion joints?

Expansion joints are used in all kinds of different sectors and in a huge range of different industrial contexts. Essentially, wherever there is a need to control pipework movement expansion joints are required.

What different varieties of expansion joints are there?

Expansion joint failure modes

Expansion joint failure can occur for various reasons, but experience shows that failures falls into several distinct categories.

补偿器选用技巧

补偿器采用矩形截面,圆角波形,管道中单个膨胀节承受二维方向位移。由2个膨胀节组成的肘接管道可承受三维方向位移。矩形圆角金属波纹膨胀节有全高、半高型、按照烟道尺寸,应力应变要求用户可多波节选用。

波纹膨胀节与管道支座的安装方法详见下图,在安装过程中必须一致遵守。

Reliable research on Expansion joint

Compensator reliability is by the design, manufacture, installation and operation and management and other aspects of the composition. Reliability should also be considered from these aspects.

Pipe Expansion Joints

Pipe expansion joints are also known as compensators, as they 'compensate' for the thermal movement.

Ducted Air Systems

Expansion joints are required in large ducted air systems to allow fixed pieces of piping to be largely free of stress as thermal expansion occurs.

补偿器疲劳测试

疲劳寿命设计由波纹管补偿器的失效类型及原因分析可以看出,波纹管的平面稳定性、周向稳定性及耐腐蚀性能均与其位移量即疲劳寿命相关。过低的疲劳寿命将会导致波纹管稳定性及耐蚀性能下降。根据试验和使用经验,用于供热工程的波纹管疲劳寿命应不小于1000次。

Metallic Pipe Expansion Joints

Metal pipe expansion joints can withstand the design temperatures, pressures, as well as, provide the capacity necessary to absorb thermal growth of the piping system.

What is the Function of Stainless Steel Bellows Expansion Joint?

Stainless steel bellows expansion joint is the compensating elements installed in pipelines, machines and containers, we often call it compensator.

Stainless steel bellows expansion joint mainly has three basic movement types: axial movement, lateral movement and angular movement.

What Are Expansion Joints?

Expansion joints are devices containing a bellows membrane that are designed to absorb dimensional changes, such as those that occur due to thermal expansion or contraction of a pipeline, duct or vessel.

There are several different material of abrasion resistant pipe

Each grade is typically made to a specific Brinell hardness value, as opposed to other steels that are made with tensile strength and toughness in mind.

SHS ceramic lined
SHS are currently being developed the world over for the production of powders and near-net shape components of advanced materials.
Ceramic tile lined pipe
has very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe and gives a very smooth surface.
Ceramic ring composite steel pipe
The wear resistant ceramic ring is a special kind of ceramic with Al2O3 as the main raw material and the rare metal oxide as the flux.

Abrasion occurs when materials are rubbed across one another over a period of time.
