GB/T 11618.1-2008Pipe fittings of copper and copper alloys - Part 1: Fittings of braze welding type (English PDF)

Foreword

GB/T 11618 "brass fittings" is divided into two parts.

--- Part 1. brazed tube;

--- Part 2. compression fittings. This section GB/T 11618 Part 1. This Part replaces GB/T 11618-1999 "brass fittings." This section compared with the GB/T 11618-1999, the main changes are as follows:

--- Modify the socket connection size. II series of commitments in this section, the outer diameter of the socket to allow deviation by the EC standard BSEN1254- 1.1998 "Part 1 of copper and copper alloy tube. soldering or brazing connected accessories" (in English), materials, connectivity, health Health and other related content with reference to the German standard DVGW W534.1995 "means the fittings and pipe connections" (in English) selected Appropriate national standards.

--- Modify the nominal diameter, extending from DN6mm ~ DN200mm is DN6mm ~ DN300mm.

--- Retained the original standard in fourth gear copper tube outer diameter, in parallel form included for easy selection of marine pipeline. Appendix A of this section is an informative annex. This part is proposed by the China State Shipbuilding Corporation. This part of the National Marine Machinery Standardization Technical Committee piping attachment points Technical Committee. This section is drafted. Tianli Pipe Fittings Co., Ltd., China Shipbuilding Technology and Economy Research Institute, the International Copper Association (China), Shanghai East Zhonghua Shipbuilding (Group) Co., Ltd., Cixi Jinlong Copper & Aluminum Pipe Manufacturing Company, Sheng Linhai City Star Copper Tube Co., Ltd..

1 Scope

GB/T 11618.1-2008 is the Chinese national standard on pipe fittings of copper and copper alloys - part 1: fittings of braze welding type, 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 4 August 2008 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 February 2009. Classification: ICS 47.020.30, CCS U55. 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.

GB/T 11618 in this section specifies the size of the connector brass press GB/T 18033 brazed brass fittings (hereinafter referred to as brazing pipe Member) classification, requirements, test methods, inspection rules, marking, packaging, transportation and storage. This section applies to the nominal pressure not more than 1.6MPa, the nominal diameter of not more than DN300mm, for delivery of domestic water (cold water, Hot water), drinking water, gas and non-corrosive to copper media other brass Road brazed tube design, manufacture and acceptance.
