T/GZHG 006-2017 The interlocking ribbed hollow wall steel-plastic composite woven pipe
Basic Information
Scope
Main technical content: 6.1 The color of the pipeline should be uniform and consistent. 6.2 Appearance 6.2.1 The inner wall surface of the pipeline should be smooth, with no bubbles or visible impurities on the inner and outer walls, and no separation of the welding seams on the pipe wall. 6.2.2 The end face of the pipeline after cutting should be repaired and welded, with no burrs or exposed steel strips. 6.3 Specifications and dimensions 6.3.1 The effective length of the pipeline is generally 6m, and other lengths shall be agreed upon by the supplier and the buyer. The actual length of the pipeline should not have negative deviations. 6.3.2 Other specifications and dimensions of the pipeline shall comply with the requirements of Table 5. Table 5 Specifications and Dimensions 5≥12.5 SN16≥16 SN20≥20 Impact performance (TIR)/% (at room temperature)≤10 The flexural specimen should be smooth, without reverse bending or cracking. Oven test: There should be no delamination or cracking at the welding seams of the pipeline.
