GB/T 18477-2001The underground drainage structural pipe system with a hard polyvinyl chloride (PVC-U) -- Part 1: double wall corrugated pipes (English PDF)

Foreword

GB/T 18477 "buried drainage with a hard polyvinyl chloride (PVC-U) structure wall pipeline system" is divided into three parts.

--- Part 1. double wall corrugated pipe;

--- Zi Part 2. Reinforced Pipe (ready to develop);

--- Part 3. Axial hollow double wall pipes (preparation formulation).

This section GB/T Part of 118,477.

This Part replaces GB/T 18477-2001 "buried drainage with a hard polyvinyl chloride (PVC-U) double wall corrugated pipes." This standard revision with reference to the international standard ISO/DIS21138-1.2006 "non-pressure underground drainage and sewerage - Thermoplastics piping systems for rigid PVC (PVC-U), polypropylene (PP) and polyethylene (PE) structure wall pipe systems - Part 1. pipes, fittings and material requirements and system performance is Seeking "and ISO/DIS21138-3.2006" non-pressure underground drainage and sewerage - Thermoplastics piping systems for rigid polyvinyl chloride (PVC-U), poly Propylene (PP) and polyethylene (PE) structure wall pipe systems - Part 3. Type B is not smooth outer pipe and tube "on the hard polyvinyl chloride it requires structural wall pipe section.

This section compared with the GB/T 18477-2001 main changes are.

--- Added "definitions, symbols" chapter (see Chapter 3);

--- Increasing the size of the inner diameter of the series (see 7.3);

--- Increasing the wall thickness of the laminate, inner layer thickness requirements (see 7.3);

--- Increasing the density requirements (see 7.4);

--- Increasing system suitability test (7.5);

--- Increased in Appendices A and B.

1 Scope

This section GB/T 18477 specifies the polyvinyl chloride resin as the main raw material, extrusion underground drainage with a hard polyvinyl chloride Double wall corrugated pipes (hereinafter referred to as "pipe") material classification, structure and pipe connections, technical requirements, test methods, inspection rules and signs, Transportation and storage.

This section applies to municipal non-pressure underground drainage, outside the building drainage, irrigation and drainage pipe can also be used for communication cable threading cannula.

Taking into account the material temperature resistance, chemical resistance and can be used for non-pressure underground industrial sewage pipes.
