Different types of bellow compensators

A bellow compensator is a type of compensation element. Use the effective expansion and contraction deformation of its working body bellows to absorb the dimensional changes of pipelines, conduits, containers, etc. caused by thermal expansion and contraction, or to compensate for the axial, lateral and angular displacements of pipelines, conduits, containers, etc. It can also be used for noise reduction and vibration reduction,widely used in modern industry.

PTFE corrugated compensator

The outer body is a stainless steel metal compensator, lined with PTFE, which is resistant to various concentrations of acid, alkali, salt, and has the advantages of the pressure of the stainless steel compensator, not afraid of collision.

High temperature resistance - the working temperature is up to 250 ℃.

Low temperature resistance - has good mechanical toughness; even if the temperature drops to -196 ℃, it can maintain 5% elongation.

Corrosion resistance - inert to most chemicals and solvents, strong acid and alkali resistance, water and various organic solvents.

Weather resistance - the best aging life in plastics.

High Lubrication - The lowest coefficient of friction among solid materials.

Non-stick - is the smallest surface tension in a solid material and does not stick to anything.

Non-toxic - with physiological inertia, as artificial blood vessels and organs for long-term implantation into the body without adverse reactions.

Electrical Insulation - Resistant to 1500 volts of high voltage.

Internal pressure axial type corrugated compensator

The compensator is composed of a corrugated pipe and two end joints. It absorbs the axial displacement of the pipeline through the flexible deformation of the corrugated pipe. The two ends of the nozzle are connected with the pipeline. The fixed stud is to ensure that the compensator is corrugated during transportation. Rigid support for the tube.

Grooved Bellows

Grooved bellows is a new type of steel pipe connection compensator with many advantages. Pipe groove connection technology emerged in the United States in the 1950s and was introduced to China in the late 1990s. Since then, with its outstanding advantages such as convenient installation, reliable quality, economical and environmental protection, etc., it has been quickly accepted and promoted by the domestic market. Under the active guidance of national regulations and policies, the technology has been widely used in fire water supply, domestic water supply, central air conditioning, sewage treatment, petrochemical, thermal power and military industries, and gradually replaced the two traditional flange and welding. It has become the first technology for gas and liquid pipeline connection. Although the pipeline groove connection technology has been popularized and applied for a long time, due to the lack of relevant personnel's understanding, lack of experience, and neglect of management and other reasons, common quality problems such as loose pipe fittings and joint water seepage often occur. However, the connection operation of the grooved corrugated pipe is simple, and the original characteristics of the pipeline are kept unaffected, which is conducive to construction safety, and the system has good stability, convenient maintenance, labor and time saving, and good economic benefits, so it is widely used.
