A flexible polymeric pipe for transportation of oil, gas or water, having an unbonded reinforcing intermediate layer between two polymeric layers. The pipe has a vent for the intermediate layer which allows venting of gas from the intermediate layer through to the exterior environment. The vent is generally impervious to water but pervious to air and gas.

Provided is an apparatus for coating a girth weld and a cutback region surrounding said girth weld, said apparatus having lateral travel at least equal to the length of the cutback region and circumferential rotational travel around the pipe. The apparatus can provide a multiple component coating accurately and safely, without the need for solvent flushing of the apparatus.

Apparatus for coating pipes

A casing member for forming a connection between two tubular sections, said casing member having a first, cross-linked, heat shrinkable plastic layer, and a second, inner, non-crosslinked (or less cross-linked) layer. The casing member also has an electrically heatable member spaced inwardly from the first layer, for fusion bonding the second layer to the tubular sections.
