Temperature control for seamless steel pipe production
Update:2018-10-24 View(s):921 Keywords :seamless steel pipe, stainless steel pipe
It would be peril for using bad seamless steel pipe for oil and gas transportation. As gas’s leakage would cause disasters for customers. Thus, high quality products would be the first element when choose steel pipelines.
And talking about high quality final product, we cannot abandon the topic of the process of stress relief annealing as well as the temperature control for seamless steel pipe. It would be a landmark for producing high quality seamless pipeline for human beings. And here is the main point for temperature control during the production process.
First of all, the work piece was slowly heated to Ac 1 or less 100 ~ 200 ℃ (500 ~ 600 ℃) holding a certain time (1 ~ 3h) followed by slow furnace cooling to 200 ℃, baked and then cooled.
The, steel is generally 500 ~ 600 ℃, Iron is generally 500 ~ 550 ℃ likely to cause pearlite graphitization than 550. Weldment generally 500 ~ 600 ℃.
