Corrugated Pipe Fittings

Corrugated Pipe Coupler

Double-walled polyethylene corrugated pipe coupler for fast and dependable jointing of structured-wall pipes in gravity sewers, stormwater, and drainage.

  • Efficient jointing of corrugated pipe sections with minimal jacking force inside trenches
  • Molded from high-density polyethylene with structured walls resisting deep soil burial loads
  • Hermetic joint sealing utilizing elastomeric profile gaskets seated within outer corrugations
  • Immunity to biogenic sulfuric acid attack, municipal sewage chemicals, and grit abrasion
  • Precise dimensional sizing matching standard inside diameters of structured-wall pipe

Design and characteristics of corrugated pipe couplers

The corrugated pipe coupler is an engineered cylindrical sleeve used to join plain-end structured-wall pipes in gravity sewer and stormwater mains. Enclosing adjacent pipe ends in conjunction with elastomeric profile gaskets, it prevents sewage exfiltration into surrounding aquifers and eliminates groundwater infiltration into municipal collection systems.

In conformity with EN 13476 specifications for structured-wall polyethylene piping, couplers exhibit high ring stiffness to endure deep trench backfill and transient traffic wheel loads. The smooth hydraulic interior prevents silt accumulation and snagging of suspended wastewater solids.

Dimensional parameters and trench assembly tips

Corrugated couplers are dimensioned by internal diameter (id_mm) and are typically supplied across the 160 to 500 mm span for urban and rural gravity sewer projects.

During assembly, the profile gasket is positioned within the specified corrugation valley, and both gasket and coupler inner walls are lubricated with certified water-soluble soap lubricant. Pipes are pushed home using trench lever bars. Specify your internal diameters in our RFQ form for formal quotations.

Corrugated Pipe Coupler — FAQ

What sizes are typical for corrugated couplers?

These couplers are typically supplied based on inside diameter (id_mm) ranging from 160 to 500 mm.

Is welding required when assembling corrugated couplers?

No, coupling structured-wall pipe is a push-fit mechanical joint utilizing elastomeric gaskets, requiring zero thermal fusion.

Can corrugated couplers withstand heavy vehicular traffic loads?

Yes, engineered ring stiffness ensures that properly bedded and backfilled couplers easily endure heavy highway wheel loading.

What lubricant should be used when pushing pipes into couplers?

Only vegetable- or water-based pipe lubricants must be used; petroleum greases deteriorate elastomeric gaskets and are prohibited.
