T/CIATA 0021-2016 Pre-fabricated direct buried insulation tube forming technology specification for spray coating and wrapping of steel pipes
Basic Information
Scope
Scope: This standard specifies the structure, technical requirements, production operations, inspection methods, inspection rules, marking, storage, and transportation requirements of prefabricated directly buried insulated pipes (hereinafter referred to as anti-corrosive insulated pipes) composed of steel pipes, fused epoxy powder, polyurethane rigid foam insulation layers, adhesives, and high-density polyethylene extruded wrapped outer protective pipes. This standard applies to anti-corrosive insulated pipes used for conveying media with a temperature not exceeding 120°C (continuous working temperature) and an occasional peak temperature not exceeding 140°C, with a working pressure not exceeding 2.5 MPa.
