A New Generation of Electrofusion : A technical comparison between the new wedge coupler and the traditional cylindrical coupler for PE pipes d1000 (40”) and above. FRIATEC has developed a totally new concept of electrofusion jointing method for large bore PE pipes, d1000 mm (40”) and above. The new method completely revolts existing practice with respect to easy installation, fast progress and minimal energy consumption. Compared with standard EF fittings in large dimensions the new technique allows a dramatically reduction in processing time, eases installation and does not require additional devices on site. Basic design criterion of the fittings is maximum reliability in processing of the joint under rough site conditions as well as durable operation of the pipe system. The presentation introduces the new concept, shows the advantages of the new method and highlights processing with respect to practical and economical aspects.

This work developed a hydro-axial tension (HAT) test as a whole pipe axial tensile test and applied to evaluate the polyethylene (PE) pipe and fusion joints containing various flaws. HAT test was designed to utilize hydrostatic pressure to cause axial tension in pipes. The experimental and numerical analysis was...

The use of spoolable reinforced thermoplastic pipe (RTP) technologies in the onshore oil and gas industry has expanded significantly over the past decade. It is anticipated that interest will only continue to grow as oil and gas operators transition to transporting alternative fuels such as hydrogen and carbon...

The paper covers the growth of the polyethylene pipe sector in the Middle East from the 90s to the present. The initial slow uptake was related to ignorance of the material properties from the end users through to designers and installers. Recently the Middle East has become a world leader in the use of ever larger...

Nationally moderated and approved competency training Units and Qualifications have been established in Australia for plastics pipes within an overall Plastics Industry Training Package. Delivery of such Units over a 21 year period has contributed to a greater understanding of various plastics pipes materials,...

With the infrastructure aging and having to be extended beyond its useful life, the need for municipalities and governmental agencies to do more with less funding is even greater! As such, over the last several years, the use of HDPE for sliplining has increased in its use. Most recently, the use of HDPE for...

This paper presents rheological data on simple rigid PVC compositions lubricated paraffin wax, calcium stearate, and oxidized polyethylene wax. These three materials comprise the most widely used lubricant system for rigid PVC in North America. The influence of certain paraffin wax characteristics will be discussed....

New types of saddle fittings enable convenient and economic ways of installing branches or vents on PE pipes. In conjunction with a gate valve, branches can even be installed without disrupting service, by "hot tapping" the main pipe. In addition, pipes with localized damage such as excessively deep scratches or...

In the Middle East the environment is exceptionally aggressive for all pipe systems due to the high temperatures, the high groundwater table and the very saline soils. This obviously makes metallic pipes and cement based pipes high risk options but it also poses challenges for polyolefin (PO). In this paper the...

The home building industry has been focused on keeping the price of new housing “affordable” to the majority of American consumers. This market mantra has, to some degree, affected the quality of new construction. In the area of piping technology, there has been a notable movement away from metallic piping systems to...

The use of plastic pipes has to date been limited to operating pressures of max 10 bar / 145 psi for gas supply and 16 bar / 230 psi (25bar / 360 psi) for water supply. Polyamide – the new high-performance material for gas pipes - and multi layer pipes with integrated reinforcement allows operating pressures to be...

„No welding if media escapes”, “residual water problems” and “need for space” are phrases invariably used when repairs and integration to PE pipe systems is the topic of conversation. Quite rightly so, because clean fusion zone surfaces are an important prerequisite for a strong, homogenous PE fusion jointing. Below,...

Crosslinked polyethylene (PE-X) pipes, successfully used for decades in house installations and heating systems, have found a new and growing application in buried gas and water supply systems, in recent years. The reason for the renewed success of PE-X is due to its unsurpassed resistance to notches. The use of sand...
