Define service requirements
Use, diameter, pressure, temperature, flow, soil, depth, and expected loads are identified.
Replacement pipe for bursting must withstand pulling forces, soil conditions, operating pressure or drainage use, joining methods, bends, connections, and expected service conditions. High-density polyethylene is common for many bursting projects, but material selection should follow the application, design, local requirements, and connection strategy.
Use, diameter, pressure, temperature, flow, soil, depth, and expected loads are identified.
Strength, flexibility, fusion or coupling, pull rating, code acceptance, and repairability are reviewed.
Building entries, mains, cleanouts, valves, branches, and connections to existing materials are planned.
Pipe identification, joining records where applicable, testing, and final route information are retained.
Pipe designation, pressure class, dimension ratio, resin, markings, and listing matter.
Fused, restrained, mechanical, or solvent-welded joints have different uses and limitations.
The pipe and joints must tolerate installation forces without damage.
Document material, size, depth, route, and transition locations for future service.
Fused HDPE is common because it is continuous and flexible, but project requirements determine the final choice.
Some systems and projects can use restrained or specialized PVC, but equipment, joints, route, and specifications must support it.
It may be the same size or larger where conditions and design permit.
Approved transition fittings, couplings, fusion, adapters, or fabricated connections are selected for the materials and use.
