GB/T 14173-2008Specification for manufacture, installation and acceptance of steel gate in hydraulic and hydroelectric engineering (English PDF)

Foreword

This standard replaces GB/T 14173-1993 "flat steel gate technology" and GB/T 814-1989 "Radial Gate General Technology Conditions ", and incorporated by reference incorporated into SL37-1991" Eccentric - hinge Radial Gate technical conditions ", SL/T 57-1993" flat sprocket gate technology Operation condition "and DL5018-2004" hydroengineering manufacture and installation of steel gate and acceptance of "related content.

The standards are compared with the original standard was mainly the following changes.

--- Scope extended to all water conservancy and hydropower engineering and other engineering steel gate of manufacture, installation and acceptance;

--- Amendment adds the requirements of quality steel surface and surface imperfections;

--- Welding procedure qualification requirements according to the provisions of GB/T 19866 and GB/T 19868.4, GB/T 19869.1 performed;

--- For the use of new materials, the head is greater than or equal to 80m complex gate structure proposed should increase the proportion of non-destructive testing inspection Claim;

--- Increasing the surface of the weld NDT acceptance level of provisions;

--- Increased when machined need to maintain dimensional tolerances should be taken to eliminate the stress treatment requirements;

--- Increased when the structure size requirements should adopt a stable overall stress relieving heat treatment or VSR treatment should not be used locally Heat treatment requirements;

--- Combination weld quality standards have been modified;

--- Of steel castings and forgings quality classification;

--- An increase of one or two types of steel castings surface NDT inspection requirements;

--- Specifies the technical requirements and acceptance of manufacturing forgings shall comply with JB/T 6397 or JB/T 6396 requirements;

--- Adds a kind of main rail surface forging NDT inspection requirements;

--- Provision charge compression, compression type seal radial gate door leaf panel processing, the panel thickness tolerances shall be not less than the local pattern size;

--- Increased requirements for engineering plastics alloys.

Appendix B of this standard is a normative appendix, Appendix A, Appendix C, Appendix D is an informative annex.
