T/CSTM 00246-2021 Technical Specifications for Pressure-Resistant Composite Hoses Used for Lining Steel Pipes and Construction Techniques
T/CSTM 00246-2021
Basic Information
Scope
Scope: This document specifies the product classification, technical requirements, test methods, inspection rules, marking, packaging, transportation, storage, quality acceptance, and construction operation requirements for pressure-resistant composite hoses used in steel pipelines (hereinafter referred to as "hoses"). This document applies to the inner lining repair of existing metal pipelines and the anti-corrosion protection of new pipelines. The hoses are suitable for the inner lining of refined oil and heating water pipelines, as well as oil collection, water injection, water flooding, and polymer injection applications. The applicable pipe diameter range is DN65~DN800, and for sizes outside this range, this document can be referenced for implementation.
