Weholite product overview

As a viable alternative to traditional materials such as concrete pipes, Weholite is a large diameter gravity/low pressure structured wall pipe made from high density polyethylene (HDPE) resin. With Weholite, raw material properties have been combined with advanced product technology to create a lightweight engineered pipe with superior loading capacity.

How is Weholite used?

Weholite large diameter plastic pipe products are used to convey liquids or air, below ground level, above ground or under water in gravity applications underwater and gravity applications. Large diameter plastic pipe can be joined in a variety of ways from the non-watertight plastic band to the 100% watertight Teekay mechanical coupler or hand extrusion weld, to the full penetration machine weld for marine applications.

Standard Weholite can be used at a continuous operating pressure of 1 bar, with LP Weholite suitable for pressures up to 2 bars. For specific applications please contact us for more information.

Asset Weholite provides all the technical advantages of polyethylene solid wall pipes, but the substantial savings in weight and ease of installation offers lower overall installed costs than traditional materials.
