20G steel pipe for large oil field steam pipeline, so 20G steel pipe must have good mechanical properties. This requires the 20G steel pipe to have excellent metallurgical quality and reasonable composition collocation in the heat affected zone near the weld seam under the long term high temperature service strip will not have graphitization tendency.
According to the technical conditions of oil field ordering and the technical requirements of 20G steel pipe rolling. The control of smelting composition is based on the principle of upper limit of carbon internal controlled composition of molybdenum and manganese.
The main purpose is to ensure the performance of 20G steel pipe at room temperature while taking into account the temperature properties of the 20G steel pipe. Reducing carbon content is good for ductile plasticity and weldability of 20G steel pipe. It can reduce graphitization tendency of 20G steel pipe under high temperature and long term service conditions.
We can supply 20G steel pipe with high quality and different size. So if you have any need in 20G steel pipe, please contact us freely. We can reply you as soon as possible. Of course we can offer the more useful information about 20G steel pipe for you. Welcome to cooperate with Katalor.
