GB/T 32475-2016Rubber hose and hose assemblies for coal seam water injection,gas drainage and drilling plugging (English PDF)

GB/T 32475-2016 is the English-translated version of 煤层注水、钻孔封堵及瓦斯排放橡胶软管和软管组合件.

GB/T 32475-2016 specifies the terms and definitions, the type, the hose assemblies, the dimensions and tolerances, the technical requirements, the test frequency and the marking, packaging, transport and storage of rubber hoses and hose assemblies for coal seam water injection, gas drainage and drilling plugging.

Clause 1 states that it applies to such hoses and hose assemblies with an outer diameter of 33 mm to 128 mm and a working temperature of 0 °C to 80 °C. Clause 2 cites GB/T 5563 on the hydrostatic testing of rubber and plastics hoses and hose assemblies, GB/T 7528 on their terminology, GB/T 9572-2013 on the measurement of their resistance and conductivity, GB/T 9573 on the measurement of hose dimensions and hose assembly lengths, GB/T 9576-2013 on the guide to their selection, storage, use and maintenance, GB/T 9577 on their marking, packaging and transport rules, and GB/T 15907 on the flammability test method for rubber and plastic hoses.

Clause 3, Terms and definitions, takes its terms from GB/T 7528 and defines the expanded outside diameter as the maximum outer diameter of the hose after expansion at a predetermined internal pressure.

The following clause, whose heading the draft garbles, divides the hoses by purpose and structure into two types: type 1, suitable for coal seam water injection and drilling plugging, made up of a rubber inner liner, two or four wire reinforced layers and an outer cover layer, and type 2, suitable for coal seam water injection, drilling plugging and gas drainage, made up of a rubber inner liner, two or four wire reinforced layers, an outer rubber coating and a built-in steel pipe.

The draft on the source page ends with that type classification, so the dimensions and tolerances, the technical requirements and the test provisions are not shown, and the page carries no summary of its own.

The page gives ICS 73.100.30 and 83.140.40 and Chinese classification G42, estimates the text at 11,134 words, and records that the standard was proposed by the China Petroleum and Chemical Industry Association and administered by the National Rubber and rubber products Standardization Technical Committee (SAC/TC35). It was issued on 24 February 2016 and has applied since 1 September 2016.
