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.

Pressure equalization in composite pipes

A method for forming a connection between two tubular sections having a polymeric outer surface jacket, using electrofusion to fusion bond a casing of similar, non-crosslinked polymer to the outer surface of the tubular sections.

Apparatus and system for electro-fusion of polyethylene pipeline

An apparatus for heating an elongate tubular article, such as a heat shrinkable sleeve applied around a welded pipe joint during pipeline construction. The apparatus is in the form of a frame which can be disposed around the article, the frame having a heater device having both longitudinally disposed heating zones and radially disposed heating sectors, each of which can be independently controlled. Alternatively, or in combination, the apparatus can have an air circulation system. Also, a method for shrinking a heat shrinkable sleeve comprising use of said apparatus.

Apparatus containing multiple sequentially used infrared heating zones for tubular articles

An automated heat shrink device, useful for forming a connection between two tubular sections having a polymeric outer surface jacket, for example, a connection between two sections of a district heating pipeline, and a method of use thereof. The device is configured such that it requires minimal clearance to either side of the pipeline when being used.

Apparatus for applying heat shrinkable casings onto preinsulated pipe joints
