UDC National Standard of the People’s Republic of China P GB/T 50184-2011 Code for Acceptance of Construction Quality of Industrial Metallic Piping ISSUED ON. DEC 24, 2010 IMPLEMENTED ON. DEC 01, 2011 Jointly issued by. Ministry of Housing and Urban-Rural Development; General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China. Foreword This Code, on basis of "Standard for Quality Inspection and Assessment of Industrial Metal Pipeline Engineering" (GB 50184-93), is reserved and completed by China Petroleum & Chemical Engineering Survey and Design Association and China National Chemical Engineering Third construction Co., Ltd. jointly with organizations concerned according to the requirements of "Notice on Printing and Publishing ‘Development and Revision Plan of National Standard for Project Construction 1999’" (JIANBIAO [1999] No. 308) by Ministry of Construction. During the revision process, the drafting group revised, examined and finalized this Code based on wide investigation and study, earnestly summarizing the practical experiences and making reference to the relevant international standards and foreign advanced standards as well as extensively soliciting for opinions. This Code comprises 9 chapters and 4 appendixes with the main contents as follows. general provisions, terms, basic requirement, examination of pipe work components and materials, machining of piping, welding and heat-treatment after welding of piping, piping installation, inspection, examination and test for piping, blowing and cleaning of piping, etc.. There have been some significant changes in this Code in the following technical aspects. 1. The non-applicable scope was deleted. 2. The Chapter of Terms was added. 3. The evaluation provisions for "Excellent" grade engineering was deleted and the inspection item was modified to dominant item and general item. 4. Provisions for the permissible deviation of measured value and quantity value of the random inspection point in sub-item project were deleted. 5. Provisions for general quality acceptance of miter elbow, welded lap joint, piping support and hanger fabrication were added. 6. Relevant provisions for quality acceptance of welded connection of branch pipe and main pipe as well as the fillet weld of flange were added. 7. Provisions for the general quality acceptance of zirconium non-ferrous piping, jacketed pipes and valves installation were added. 8. Provisions for the examination grade division of piping welded seam as well as provisions for quality acceptance of technical level of welded seam surface non-destructive examination, welded seam radiographic and ultrasonic examination were added. 9. Requirements for the relevant quality acceptance of hydraulic pressure test and pneumatic test were supplemented. The provisions printed in bold type in this code are compulsory provisions and must be enforced strictly.
