Contech A2™ Liner Pipe

A2™ LINER PIPE

Proven trenchless installation to slip line existing sewer lines without the disruptions associated with open trenching.Trenchless Slip Lining Technology for the Rehabilitation of Sanitary and Storm Sewers A2™ Liner Pipe, manufactured exclusively from low fill, cell class 12454 PVC compound, the most widely accepted sewer pipe material, withstands corrosive attack from both acidic and alkaline soils and is unaffected by chemicals found in normal sewage. Relining with A2 Liner Pipe provides up to 50% cost savings over cured-in-place pipe. A2 Liner Pipe eliminates costly bypass operations because normal flow is maintained. It also gives you a new pipe with direct-bury strength of 46 psi stiffness, which means it doesn’t depend on the host pipe for long-term structural performance as cured-in-place liners do.

FEATURES

-Manufactured from low fill, cell class 12454 PVC compound -Direct-bury strength of 46 psi stiffness -Manning’s “n” of .009 -Patented, gasketed STAB-JOINT -Lightweight

BENEFITS

-Superior corrosion and abrasion resistance -Doesn’t depend on the host pipe for long-term structural performance -Allows the relined pipe to carry as much or more flow than the existing host pipe, even with diameter reductions -Meets joint tightness requirements of ASTM D3212 and is designed to remain watertight up to 5 degrees angularity -Workers can slip line at a rate in excess of 200 feet per hour

DETAIL

With a Manning’s “n” of .009, A2 Liner Pipe restores hydraulic capacity of reinforced concrete and vitrified clay pipes with offset joints, cracks, spalling, or protrusions. Its glossy-smooth interior allows the relined pipe to carry as much or more flow than the existing host pipe, even with diameter reductions.Construction crews can slip line with A2 Liner Pipe at a rate in excess of 200 feet per hour. And because it is lightweight, you can use smaller, less expensive equipment for handling and joining. A2 Liner Pipe’s patented gasketed STAB-JOINT® is designed to remain watertight up to 5 degrees angularity and ensures a positive connection even when slip lining misaligned, obstructed, or curvilinear sewers.

CMP AND PVC PIPE FOR PIPE RELINE

Lining inadequate or failing structures with corrugated metal material or plastic pipe uses little of the available area, thereby preserving the maximum amount  of the original opening. Due to the hydraulic efficiency of Contech products, often a smaller structure provides the same hydraulic capacity as the original because of the low Manning “n” factors of A-2000™ and A2™ Liner PVC pipes and HEL-COR^® and ULTRA FLO^® CMP.

Existing culverts and arches are generally lined with structures of the same shape, though slightly smaller in size. Rectangular openings can be lined with round, elliptical or pipe arch structures. Corrugated metal structures can fit almost any existing shape.
