GB/T 46167-2025 Flexible hoses and hose assemblies for fracturing—Specification
Basic Information
Scope
This document specifies the classification, structure, requirements, inspection rules, marking, storage, and transportation requirements for fracturing flexible hoses and hose assemblies, and describes the test methods for their related performance. This document is applicable to flexible hoses and hose assemblies used in acid fracturing operations between the fracturing truck (skid) and the fracturing wellhead. The transported medium includes acidized fracturing fluid, proppants, hydrochloric acid with a maximum concentration (mass fraction) of 30%, liquid carbon dioxide, nitrogen, etc. The inner diameter ranges from 38 mm to 180 mm, with a maximum working pressure of 103.5 MPa and 138.0 MPa, and a working environment temperature of -35℃ to +45℃, and a working medium temperature of -35℃ to +100℃. The recommended maximum flow rate and maximum flow volume for the hoses are provided in Appendix A.
