If you have come to this page, it means that you plan to perform heat treatment in accordance with the standard of organization 00220368-019-2017 "Heat treatment of petrochemical equipment and its components". Or, at least, this regulatory document has drawn your attention
It should be noted that this standard was introduced instead of the standard of organization 00220368-019-2011 from August 1, 2017. This 2011 edition was introduced instead of RTM 26-44-82 "Heat treatment of petrochemical equipment and its elements".
Our company has participated in developing this STO.
This regulatory document establishes the requirements and basic technological recommendations for the heat treatment of welded petrochemical, chemical and gas equipment, its elements and assembly units, technological pipelines made of carbon steels, alloy steels, high-alloy corrosion-resistant steels, two-layer and dissimilar steel, as well as alloys on iron and nickel bases.
This standard applies to the development of technological processes, design, manufacture, installation and repair of vessels, devices operating under pressure of not more than 21.0 MPa, vacuum with a residual pressure not lower than 665 Pa (5 mm Hg), without pressure (underfilling) and at wall temperatures not lower than minus 70 ° С, technological pipelines operating under pressure up to 320 MPa, intended for use in technological installations of chemical, petrochemical, oil refining, oil, gas and other industries..
Within the framework of this article, it is not possible to explore all the intricacies and details of this regulatory document.
