The system is approved for both steel casing and with modifications, pressure pipe applications. The T-5, T-7 and Type HDD joints each bring a different application- specific solution to the pipe connections. Standard specifications ensure that all pipe manufactured by Permalok® meet stringent guidelines. Joint quality is further enhanced because the Permalok® connector is consistently round, true and perpendicular to the pipe axis. Its unique machined groove makes stabbing and aligning easy and expeditious. The Permalok® design, combined with the use of a sealant such as RTV silicone, will not leak even under considerable groundwater pressure.
Permalok® Steel Coatings and Linings
Permalok® uses several options for our coatings and linings. The primary materials applied to Permalok® products are:
Coal Tar Epoxy – A catalyzed, two-component lining that combines the corrosion-resistant characteristics of coal tar pitch with those of epoxy resin, resulting in a cured lining that will tolerate reasonable impact abrasion and flexing.
Bitumastic – Bitumastic is made from coal tars and blends of resins such as epoxy. A trade name often associated with long-term protection from water penetration, Bitumastic is an economical, heavy-duty material which protects piping subjected to water immersion.
Polyurethane – Polyurethanes are used extensively in the pipe coating industry because they exhibit excellent corrosion resistance, abrasion resistance, toughness and chemical resistance, as well as a wide range of useful mechanical properties. Fast-setting, high-solids polyurethane has been used to line and coat steel pipe for various demanding trenchless and open-cut applications.
Power Lonestar “Powercrete®” – An epoxy based polymer concrete which protects the steel pipe under severe handling conditions. It is highly abrasion-resistant, and provides a smooth surface that allows for less drag resistance than standard concrete.
