High-parameter, Special Alloy Metal Bellows and Components

With the rapid development of modern industry, the number of pipelines carrying flammable, explosive, highly toxic and other special media is increasing day by day. Valves used on these pipelines and devices have special and strict requirements for external leakage sealing. The general packing seal device can no longer meet the requirements, and bellows assemblies need to be adopted as sealing components. It provides an axially deformable metal spacer between the valve stem and the process fluid inside the valve body, forming a dynamic seal to eliminate leakage at the valve stem.

Metal Bellows and Components for Elastic Sealing

Metal Bellows and Components for Elastic Sealing

In addition to its elastic properties, the metal bellows used for elastic sealing also possess multiple properties such as pressure resistance, sealing, corrosion resistance, temperature resistance, and impact resistance. It is a multi-functional component. The "Huibo" brand corrugated pipe series products produced by the company, as key core components, have been widely applied in the research and development tasks of many national major projects, contributing to the development of China's science and technology and leading the progress of the industry.

Metal Hose

Metal Hose

Metal Hose

Metal hoses are important connecting components in engineering technology, composed of corrugated flexible tubes, mesh sleeves and joints. It is used as a compensating element, sealing element, connecting element and shock-absorbing element in various gas and liquid transmission pipeline systems as well as length, temperature, position and Angle compensation systems, and is applied in various fields such as petrochemical, mining electronics, mechanical shipbuilding, medical and health care, light textile electronics, energy and construction.

Electrodeposited Metal Corrugated Pipe

Electrodeposited Metal Corrugated Pipe

Electrodeposited metal bellows, as elastic elements, are widely used as sensitive components in instruments and electric instruments, as sealing elements in mechanical equipment, as isolation devices for two media, as temperature compensators in pipelines, and can also be applied in pneumatic accessories, the electronics industry, vacuum switches, and other fields.

Axial Type Metal Corrugated Expansion Joint

Metal Corrugated Expansion Joint

Axial Type Metal Corrugated Expansion Joint

Axial metal bellows expansion joints are mainly used to compensate for the axial displacement of pipelines caused by thermal expansion and contraction, and they are a commonly used type of compensator.

Force-balanced Metal Corrugated Expansion Joint

Metal Corrugated Expansion Joint

Force-balanced Metal Corrugated Expansion Joint

Straight pipe pressure balanced bellows expansion joints, also known as straight pipe pressure balanced bellows compensators or straight pipe pressure balanced compensators, can compensate for axial displacement in the system. The internal pressure thrust is self-balanced and can be used in high level straight pipelines or large-diameter pipelines where fixed supports are not suitable.

Disc spring type metal corrugated expansion joint

Metal Corrugated Expansion Joint

Disc spring type metal corrugated expansion joint

The disc spring type metal bellows expansion joint is composed of structural components such as bellows, flange assemblies and disc spring force compensation devices. It uses the disc spring preload force to balance the blind plate force generated in the pipeline due to the installation of compensators

Hinge-shaped Metal Corrugated Expansion Joint

Metal Corrugated Expansion Joint

Hinge-shaped Metal Corrugated Expansion Joint

The hinged type metal bellows expansion joint is composed of a connecting pipe, a bellows pipe and a hinge connected to the connecting pipe. It absorbs angular displacement of the plane. When absorbing displacement, two or three hinged expansion joints should be used in combination. Meanwhile, the hinge has the ability to withstand internal pressure thrust.

Flanged Metal Corrugated Expansion Joint

Flanged Metal Corrugated Expansion Joint

The flanged metal corrugated expansion joint uses the straight edge section of the corrugated pipe with the pipe opening turned outward to cover the flange sealing surface. When connected with the matching flange, it is sealed with an "O" ring.

Transverse Type Metal Bellows Expansion Joint
