Foreword

This standard is GB/T 14382-1993 "pipe with a three-pass filter" revision. This standard and GB/T 14382-1993 compared to the main changes are as follows:

--- Increasing the term;

--- DC T-type filter, increasing the lengthened;

--- Pore size of the socket has been modified;

--- DC T-type filter, an increase of PN16, PN25 and PN40 three pressure level;

--- Increasing the filter main dimension tolerance and shape tolerance;

--- Increased requirements for non-destructive testing of butt weld;

--- Increased the pressure strength test pressure at specific design temperature and design pressure conditions;

--- Canceled the hydraulic seal test. From the date of implementation of this standard instead of GB/T 14382-1993. The standard proposed by China Machinery Industry Federation. This standard by the National Standardization Technical Committee pipe accessories. This standard was drafted. the machine Productivity Promotion Center, Qidong mixer Co., Ltd., Wuxi Hua Er Tai Machinery Manufacturing Co., Henan mountains Valve Co., Ltd. The main drafters of this standard. Huang Weixian, Li Junying, Feng Feng, Li Zhongyun, Yangquan Qing. This standard replaces the standards previously issued as follows:

--- GB/T 14382-1993. Pipeline with three-pass filter

1 Scope

GB/T 14382-2008 is the Chinese national standard on tee strainers for fluids for pipes, in the field of fluid systems and general-purpose components. 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 25 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 April 2009. Classification: ICS 23.040.60, CCS J15. 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 pipeline with three-pass filter (hereinafter referred to as filter) classification, requirements, test methods and inspection rules. This standard applies to nominal size DN400 and below, nominal pressure PN16 ~ PN40 and Class150 ~ Class300, operating temperature Range of pipe filters of -196 °C ~ 540 °C.
