PRODUCT CENTER

The company's leading products are divided into engine turbocharger oil pipe series, metal corrugated pipe series, EGR exhaust corrugated pipe series, internal pressure forming pipe series, large metal corrugated pipe systems for agricultural and marine machinery, various types of clamping structure combined hose series, heavy truck rubber bushings, metal structural parts and machined parts, etc.

Metal hose

A flexible connection component composed of a braided mesh sleeve, bellows, and joints, used to compensate for displacement, absorb vibration, and transport media in flexible pipeline components. According to the connection method, it is divided into flange type, pipe joint type, and threaded type. We provide customized services. If you need a special design, please feel free to contact us!

Axial expansion joint with rotating flange

Components: Bellows tube body (single-layer/multi-layer), connection end (flange/welded interface/threaded joint), protective sleeve (metal braided mesh/insulation layer), fixed bracket

Drone accessories

This type of product is currently mainly divided into double-wall pipes and double-wall expansion joints for connection. It is mainly used in the transmission of new energy ship fuels such as natural gas, methanol, ammonia, etc., or in pipeline systems that require common rail dual-medium transmission in chemical industries.

Reinforced Double Sphere Rubber Expansion Joint

1. Small volume, light weight, good elasticity, easy to install and maintain. 2. It can produce lateral, axial, and angular displacement during installation, and is not restricted by the user's pipeline eccentricity or flange non-parallelism. 3. It can reduce structural transmission noise and has strong vibration absorption capacity during operation.

Axial expansion joint with smooth fixed flange

Components: Bellows tube body (single-layer/multi-layer), connection end (flange/welded interface/threaded joint), protective sleeve (metal braided mesh/insulation layer), fixed bracket

[PVC] Single Sphere PVC Flange Rubber Joint

TS pressure pipeline production license for the rubber joint industry, ISO9001-2015 international quality system certification, ISO1400:2004 environmental management system certification, OHSAS18001:2007 occupational health and safety management system certification, equipment type test certificate, etc.

Water plant 304 stainless steel rubber hose connector

304 stainless steel rubber joint is assembled from rubber sphere and stainless steel flange. The flange has good gloss, high temperature resistance, and corrosion resistance. It is widely used in engineering projects with high requirements. It is strictly forbidden to install the rubber expansion joint beyond the displacement limit during installation. When installing rubber joints on flat ground, in suspension, or vertically, the actual working axial displacement pressure of the rubber joint should be less than the supporting force of the pipeline; otherwise, an anti-pull-off device should be installed to prevent it from being pulled off under pressure during operation.

Galvanized flange flexible rubber joint

The main body of the rubber joint is composed of a rubber tube and a flange. Many customers believe that the most important part of the rubber joint is the rubber tube, but the flange on the rubber joint is also very important. The flange on the rubber joint is mainly used as the core equipment for connecting the rubber joint to pipelines and pumps. The rubber joint is due to its special material properties.
