GB/T 22051-2008Cold-expansion fittings with sliding compression-sleeves for cross-linked polyethylene (PE-X) pipe (English PDF)

Foreword

This standard and ASTMF2080-05 "cross-linked polyethylene (PE-X) pipes cold-expanded metal compression ferrule fittings," the degree of non-conformity Equivalent. The main technical differences between this standard and ASTMF2080-05 follows.

--- The American series nominal size nominal size change to metric series male will change US-made pipe thread BSP;

--- The maximum operating temperature of the pipe from 82 °C to 90 °C, the maximum working pressure from 0.69MPa to 1.0MPa;

--- Increasing the pipe body airtight performance requirements;

--- Change the system suitability requirements and test methods for fittings;

--- Cancel About metric table assembly drawings and appendices;

--- Increase slip tight connection sleeve cold expansion fittings and pipes are attached as Appendix A.

Appendix A of this standard is a normative appendix.
