It is used to convey liquids or air, below ground level, above ground or under water in gravity applications underwater and gravity applications. Pipes 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 Asset International ltd.
