Combined Connection Methods for Steel Belt Reinforced Pipes
2019/02/06
Combined connection methods for steel belt pipes refer to the joint application of two or more connection techniques in actual projects to boost connection strength, sealing performance and adaptability to special working conditions. The mainstream combined connection solutions based on authoritative industry data are as follows:
Common Combined Connection Methods
Hot Melt Extrusion Welding + Heat-shrinkable Sleeve/Belt
For large-diameter pipelines and projects with high pressure requirements, rigid fusion connection is completed firstly via hot melt extrusion welding. Then heat-shrinkable sleeves or belts are wrapped on the outer layer for secondary sealing and reinforcement, effectively improving anti-leakage performance.
Electro-fusion Belt Connection + Heat-shrinkable Coupling
After finishing main connection with electro-fusion belts, install heat-shrinkable couplings outside the joints to strengthen anti-corrosion and sealing effects. This method is ideal for corrosive environments and projects requiring long-term stable operation.
Clamp Connection + Rubber Ring Sealing
It is mainly applied to emergency rush repairs and transitional connection of dissimilar materials. Sealing is realized by compressing rubber rings with clamps. As a mechanical connection form, it can be matched with other rigid connection methods for special pipeline joints.
Hot Melt Extrusion Welding + Auxiliary Socket Rubber Ring Sealing
To achieve double safety guarantee in key projects, socket rubber ring sealing is adopted on the basis of hot melt welding. It is especially suitable for high water level environments and major main drainage pipelines.
