GB/T 11038-2009Welding specification for pressure parts of marine auxiliary boiler and pressure vessel (English PDF)

Foreword

This standard replaces GB/T 11038-2000 "marine auxiliary boiler and pressure vessel pressure parts for welding." This standard compared with GB/T 11038-2000, the main changes are as follows:

--- The standard name to "marine auxiliary boiler and pressure vessel pressure parts welding technology";

--- To increase and refine the relevant provisions and requirements of the welding procedure qualification;

--- Increasing the general requirements for welding materials;

--- Increase distance requirements for fillet welds and butt welds main pressure parts between the edges;

--- An increase in the furnace for the heat treatment is not large workpiece heat treatment requirements;

--- Information about the requirements and mechanical properties of welded test specimens welded test specimens. The standard proposed by China State Shipbuilding Corporation. This standard by the National Marine Machinery Standardization Technical Committee. This standard was drafted. Green Zhangjiagang Shazhou Boiler Co., Ltd., Qingdao Marine Boiler Factory Co., Ltd., China Shipbuilding Industry Integrated Technology Surgery Institute of Economic Research, China Classification Society Qingdao Branch, Qingdao Kai boilers Equipment Co. The main drafters of this standard. Liu Guoliang, Weihua Xing, Qiu Yudong, Zhang Yonggang, car Rui, Wang Bo, Zhong Chongxin. This standard replaces the standards previously issued as follows:

--- GB 11038-1989, GB/T 11038-2000. Marine auxiliary boiler and pressure vessel pressure element Welding conditions

1 Scope

GB/T 11038-2009 is the Chinese national standard on welding specification for pressure parts of marine auxiliary boiler and pressure vessel, in the field of shipbuilding and marine structures. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 9 March 2009 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 November 2009. Classification: ICS 47.020.20, CCS U41. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the marine auxiliary boiler and pressure vessel (hereinafter referred to as Boiler and Pressure Vessels) pressure parts welding materials, welding technology Evaluation, welding, weld inspection, mechanical properties and heat treatment after welding test welding test plate. This standard applies to the design pressure is less than 2.5MPa, medium is water and saturated steam boiler; design pressure is less than 6.4MPa, Medium is water or air pressure vessel.
