CJ/T 225-2011Metal reinforced polyethylene (PE) spirally corrugated pipe for underground sewer (English PDF)

Foreword

This Standard is prepared according to the rules specified in GB/T 1.1-2009.

This Standard is an revision to CJ/T 225-2006 "Metal Reinforced Polyethylene (PE)

Spiral Corrugated Pipe for Underground Sewer". Compared with CJ/T 225-2006, the

changes of main technical content are as follows.

— INCREASE technical indictors' requirements of raw materials, and ADD

galvanized steel-strip.

— PROPOSE the requirements of dividing sections according to the pipe diameter,

and IMPROVE indicators for the tensile strength of the laminated wall and

welding seam.

— ADD planar-shaped port pipe that is vertical to axis in pipe structure.

— PERFORM larger revision on connection type and method. ADD planar-shaped

port form in connection type (listed in Annex C).

— ADD ring-stiffness SN10 level.

— ADD pipe dimensions of 2200, 2400, and 2600 specifications.

— ADD Annex B Test Method of Adhesive Resin Water Immersion Resistance

Performance, Annex C Common Pipe Connection Type, Annex D Preparation of

Ring-stiffness Sample, and Annex E Preparation Method of Pipe Laminated Wall

Tensile Strength Test Sample.
