4 by Order of the Federal Agency for technical regulation and Metrology dated December 25, 2015 2204 N-St inter-state standard GOST 33229−2015 introduced as a national standard of the Russian Federation from August 1, 2016.
5 this standard was developed based on the national standard of Russian Federation GOST R 55442−2013 «Pipe for boiler and heat exchange equipment. Specifications. Part 1. Seamless steel tubes for operating under pressure is not more than 6.4 MPa and at temperatures not above 400°C».
By order of the Federal Agency for technical regulation and Metrology dated December 25, 2015 2204 N-St GOST R 55442−2013 abolished from 1 August 2016.
6 INTRODUCED FOR THE FIRST TIME
Information about the changes to this standard is published in the annual reference index «National standards», and the text changes and amendments — in monthly information index «National standards». In case of revision (replacement) or cancellation of this standard a notification will be published in the monthly information index «National standards». Relevant information, notification and lyrics are also posted in the information system of General use — on the official website of the Federal Agency for technical regulation and Metrology on the Internet (www.gost.ru)
Introduction
This standard was developed in connection with necessity of creation of normative base on pipe for boiler and heat exchange equipment and eliminating the supply of such pipes according to various standards improper purpose, does not fully meet the requirements of the Rules of design and safe operation of boiler and heat exchange equipment.
This standard is developed on the basis of special technical conditions TU 14−3-190−2004 «seamless steel Tubes for boilers and pipelines» with the addition of steel grades 09G2S and 10G2, the manufacture of pipes for boiler and heat exchange equipment provided by the Rules according to GOST 8731 «Pipe seamless hot-deformed steel. Specifications» and TU 14−3-1128−82* «seamless hot deformed steel Pipes for gas pipelines of gas-lift systems."
This standard is part of a complex of standards of tubes for boiler and heat exchange equipment.
Compared to the previously applied documents on the pipe to the specified destination in this standard clearly sets out the scope of pipe, set out the requirements on the mode of heat treatment of tubes, supplemented with the possibility of testing hardness of metal tubes, tensile tests at various elevated temperatures and testing the impact strength at various low temperatures.
1 Scope
This standard applies to cold-deformed and hot-deformed seamless steel pipe, carbon and low-alloy steels, intended for boiler, heat-exchange equipment and pipelines working under pressure of not more than 6.4 MPa and at temperatures not above 400 °C.
