Corrugated compensators play an important role in urban modernization

I believe everyone is familiar with the corrugated expansion joint, which is of great help to everyone's daily life. Since the adoption of the central heating system in my country in the mid-1980s, the corrugated expansion joint has increasingly replaced the traditional expansion joint and casing expansion joint. After decades of mature application, they have contributed to the modernization of the city.

Application of compensators in various fields of life

The rapid development of the times requires that many traditional tools and equipment be replaced by new tools and equipment. Expansion joints are widely used in various fields of life, and can also be called pipeline expansion joints, corrugated expansion joints, etc. They are often used in the industrial field to help some industries support combustion and form high temperatures. In order to facilitate people's daily life, expansion joints have been greatly improved.

Analysis of the bending resistance and design requirements of compensators

The direct-buried bellows compensator is mainly suitable for axial compensation and has super strong bending resistance. Therefore, the influence of pipeline sinking is not considered. The direct-buried bellows compensator shell and guide sleeve are protected to achieve free telescopic compensation. Other performances are the same as ordinary bellows compensators.

The stability of stainless steel bellows determines its pressure resistance

When the stainless steel bellows is subjected to a pressure in the axial direction that exceeds the pressure it can support, it will suddenly bend and lose the stability of the straight line shape, just like a compressed rod or a cylindrical helical spring. This is inevitable. If the internal pressure of the bellows exceeds a certain pressure value it can support, it will also become unstable. Experiments have shown that most of the damage to bellows in engineering is caused by this reason. Whether it is elastic seals, axial expansion compensators, or metal hoses, this problem exists.

What are the types of bellows?

Bellows are mainly divided into metal (stainless steel, carbon steel) bellows and plastic bellows. Metal bellows are mainly used to compensate for pipeline thermal deformation, shock absorption, and absorb pipeline settlement deformation, and are widely used in petrochemical, instrumentation, aerospace, chemical, electric power, cement, metallurgy and other industries. Bellows made of other materials such as plastics play an irreplaceable role in media transportation, power threading, machine tools, home appliances and other fields.

The main purpose of stainless steel metal hose

Stainless steel metal hose is a flexible part with excellent performance in modern industrial pipelines. The structure is a stainless steel corrugated pipe with one or more layers of steel wire or steel belt mesh, with joints or flange heads at both ends, used to transport various media. Its characteristics: corrosion resistance, high and low temperature resistance (-196℃～＋420℃), light weight, small size, good flexibility.

The difference between single-wall corrugated pipe and double-wall corrugated pipe

1. Construction technicians should be familiar with the drawings, understand the design intent, contact the owner, supervisor and designer in time for any problems found in the drawings, and review the drawings and keep records of the review. Installers must be familiar with the general performance of PE double-wall corrugated pipes and master the necessary operating points.

What are the performance characteristics of polyethylene double-wall corrugated pipe?

The outer wall has an annular corrugated structure, which greatly enhances the ring stiffness of the pipe, thereby enhancing the pipe's resistance to soil load. In this performance, polyethylene double-wall corrugated pipe has obvious advantages compared with other pipes.

Extrusion equipment for PVC double-wall corrugated pipe

The extrusion equipment for PVC double-wall corrugated pipe is basically similar to that for single-wall corrugated pipe, except for the forming mold for the pipe blank. However, since double-wall corrugated pipes are mostly large-diameter specifications and require more raw materials for extrusion molding, it is recommended to use a twin-screw extruder, which will be better.

Metal compensator installation method

1. Before installing the metal compensator, its model, specification and pipeline configuration should be checked to ensure that they meet the design requirements.
