51 Steel pipe network news: GB3087-82 low and medium pressure boiler seamless steel pipe standard, suitable for low and medium pressure boiler overheated steam pipe, boiling water pipe and locomotive boiler superheated steam pipe, smoke pipe, small smoke pipe and arched brick pipe High-quality carbon structural steel hot-rolled and cold-drawn (rolled) seamless steel pipe; GB8163-87 seamless fluid steel pipe standard, suitable for conveying fluid with a general seamless steel pipe, heat-conducting oil temperature range is generally 200-400 degrees, For long-term circulation under high temperature environment, GB3087-82 standard should be adopted; in GB8163, 10, 20 steel is limited to boilers whose rated outlet hot water temperature is lower than 120 degrees. The temperature of the heat transfer oil in the organic heat carrier boiler is generally 300-400 degrees, so 3087 tubes must be used.
