There is currently not a pre-insulated piping standard in the United States. The lack of standard gives each manufacturer some leeway in how products our manufactured. This is how some of the smaller manufacturers with less quality control are often perceived as equals to Thermacor by specifying engineers and owners.
This lack of standard has forced some owners and engineers to turn to European standards as a guideline for both quality and functionality. The overall standard that governs pre-insulated piping for bonded foam systems in Europe is EN253. While our products are very, very similar if not identical in many aspects, most domestic manufacturers and their piping system components have not be certified to this standard……….
……however, Thermacor’s electro-fusion pressure-testable joint closure is now fully certified to the European joint closure standard, EN489:2009!!! This standard is comprised of a water impermeability test and a weld joint stress crack resistance test.
*Thermacor strives to be on the cutting edge of quality and innovation
*We’ve manufactured electro-fusion joint closures successfully since 1997
