Тавсифи

1. Муқаддимаи мухтасари маҳсулот

Low-temperature seamless steel pipe is mainly used in petroleum, chemical, natural gas and coal as raw materials of ethylene, propylene, urea, synthetic ammonia, N-P-K composite fertilizer and pharmaceutical industry washing, purification, desulfurization and degrease production, as well as cryogenic equipment manufacturing, ultra-low temperature cold storage, transport ultra-low temperature liquefied gas pipeline and pipe components. The international low-temperature seamless steel pipe system is represented by ASTM A333/A333M-2011 (hereinafter referred to as the US standard), which is suitable for low temperature environment as low as -196℃. At present, the production and acceptance of low-temperature seamless steel pipe in the world mostly uses the US standard, and the domestic design also refers to the US standard. Among the nine grades of US standard cryogenic pipe, Gr.6 is widely used in the petrochemical industry and the fluid transport in low temperature and cold areas, and the annual demand in the US and European markets is more than 20,000 t.

2. Раванди истеҳсолӣ

Manufacturing - Tubes are made by welding processes that are seamless or do not add filler metal. Level 4 shall be made of seamless process.

табобати гармӣ

All seamless and welded pipes shall be heat treated to control their microstructure by one of the following methods.

Uniformly heated to not less than 1500F (815℃) for positive heat treatment, and then air cooling or cooling in the cooling chamber of the controlled air oxygen furnace.

The steel pipe is normalized and reheated to an appropriate tempering temperature as determined by the steel mill. The pipe reheating well controls the hot processing, so that the operating temperature of the hot forming is controlled within the hot forming temperature range of 1550 to 1750F (845-945 ° C), and then it is cooled in the control gas oxygen furnace with an initial temperature of not less than 1550 (845 ° C). This method is only suitable for non-sewn tube processes.

It is treated and reheated to the appropriate tempering temperature as determined by the factory.

When specified in the order, the sample shall be cut from the thickness test block, which is taken from the steel pipe of the heat treated stone, and shall be stress-relieved. The test block shall be progressively heated to the specified temperature, moisturized at this temperature for the specified time, and then cooled to a temperature not higher than 600F (315 ° C). The test block of grade 8 steel pipe shall be air-cooled or water-cooled at a minimum cooling rate of 300F/ (165℃/h) to a temperature not higher than 600F (315℃).
