CJ/T 192-2017Composite steel pipe stainless?steel lined (English PDF)

Foreword

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

This standard replaces CJ/T 192-2004 "Lined stainless steel composite pipe." In the drafting of this standard reference API5LD Corrosion-resistant alloy composite steel pipe, compared with CJ/T 192-2004, the main technical content changes are as follows.

--- Use of the scope of delivery of drinking water, fire water, high temperature water, air conditioning water, sewage and other water supply and drainage and steam, gas and other purposes;

--- Expand the nominal size to DN1400, according to different base pipe execution standards, the use of base pipe grade, composite pipe diameter and wall thickness increase Specific rules for allowing work pressure. Increase the specific regulations for the allowable working pressure of the different connection methods at the end of the composite pipe;

--- Added terms and definitions, order contents, weight calculation methods;

--- For the welding of welded composite pipes, increase the size of the end of the outer diameter of the provisions;

--- The shear strength of the base pipe and liner shear test increased to 0.3 MPa. Adds base pipe and lining for composite pipes larger than DN250 Tube clamping force test requirements and test methods, and stipulate that for composite pipes larger than DN250 and not greater than DN600, Test by either of the two methods.

This standard is proposed by the Institute of Standardization of Housing and Urban-Rural Development Standards.

This standard is under the jurisdiction of the Ministry of Housing and Urban-Rural Construction Water Supply and Drainage Standardization Technical Committee.
