GB/T 34391-2017Reciprocating positive displacement pumps for petroleum, petrochemical and natural gas industries (English PDF)

Foreword

This standard was drafted in accordance with the rules given in GB/T 1.1-2009.

This standard uses the translation method identical with ISO 13710:2004 "Petroleum, petrochemical and natural gas industry reciprocating positive displacement pumps" (English Version).

For the documents of our country which have correspondence with the international documents that are normative references in this standard, please refer to Appendix NA.

For ease of use, this standard made the following editorial changes.

--- Standard name changed to "oil, petrochemical and natural gas industry with reciprocating pump";

--- The unit of measurement in this standard formula ft (feet), ft/s (feet per second), psi (pounds per square inch) were changed to International Units System m (meters), m/s (meters per second), kPa (kPa);

--- "Standard" in front of the "-" is the buyer to implement the terms;

--- Added information appendix NB "flange standard and nominal pressure rating table";

--- Added information appendix NC "pump parts with the main material control table." this standard is proposed by the China Machinery Industry Federation.

This standard by the National Standardization Technical Committee pump (SAC/TC211) centralized.
