5.Frequently Asked Questions about Thermally Expanded Seamless Steel Tubes
Q:What is the difference between thermal expansion seamless steel pipe and seamless steel pipe?
A:There is a difference, the thermal expansion seamless steel pipe is what we often call the thermal expansion pipe, the steel pipe with low density but strong shrinkage, (seamless steel pipe) can be referred to as the thermal expansion pipe. A blank pipe finishing rolling process that expands the diameter of the pipe by skew rolling or drawing . Make the outer diameter of the steel pipe larger in a short time, and can produce non-standard, special...
Q:Production standard for thermally expanded seamless steel pipes
A:Hot-expanded seamless steel pipe: GB/T3087-1999 hot-expanded seamed steel pipe (seamless steel pipe): GB/T3091-2000. my country's current thermal expansion pipe production standards: thermal expansion seamless steel pipe: GB3087-1999
Q:Who knows what the material of thermal expansion seamless steel pipe is?
A:[Material] Mainly stainless steel, the materials are imported and domestic 201, 202 , 301, 304, 321, 304L, 316L , 317L, 907L, 309S, 310S. [Overview] Thermal expansion is a processing method of steel pipes, which is to process steel pipes into large-diameter steel pipes. hot...
Q:How to distinguish between heat-expanded steel pipe and seamless steel pipe?
A:Heat-expanded steel pipe is just a manufacturing process of steel pipe, both welded and seamless steel pipes can be heat-expanded. How to distinguish what thermal expansion is: on the appearance of the steel pipe, the thermal expansion is red, and the inner diameter is lead powder . We often say that the thermal expansion pipe refers to the steel pipe with relatively low density but strong shrinkage, (seamless...
Q:The difference between cold drawn seamless steel pipe and hot
A:The difference between cold drawn seamless steel pipe and hot drawn seamless steel pipe 1) The difference between hot working and cold working Hot rolling is hot working, cold drawing is cold working (2) The main difference: hot rolling is rolling above the recrystallization temperature, cold Rolling is rolling below the recrystallization temperature; cold rolling is sometimes heated, but the temperature is relatively low,...
6.20# Thermal expansion seamless steel pipe overview
20# hot-expanded seamless steel pipe mainly refers to the carbon content in this material, which is about 0.2%. This material is also more common than other high-quality carbon steels . It is commonly used in the manufacture of seamless steel pipes, molds , high-quality carbon steel plates , channel steels , I-beams and other steels . The number of meters after the expansion of the hot-expanded seamless steel pipe: the diameter of the original pipe of the hot-expanded seamless steel pipe ÷ the expanded diameter × 1.04 × the length. 20# hot-expanded seamless steel pipe speed: 100000÷(original diameter-thickness×thickness). 20# heat-expandable seamless steel pipe is widely used in steel structures , supporting bridges , transportation pipelines , etc.
7.12Cr1MoVOverview of Thermally Expanded Seamless Steel Tubes
12cr1mov hot-expanded seamless steel pipe is divided into two types: hot-rolled (extruded) seamless steel pipe and cold-drawn (rolled) seamless steel pipe due to different manufacturing processes. The main implementation standards of 12cr1mov heat-expandable seamless steel pipe are GB/T8162-2008, GB/T8163-2008, GB3087-2008, GB5310-200812cr1mov heat-expanded seamless steel pipe has higher oxidation resistance and thermal strength.

8.Overview of Q345 thermal expansion seamless steel pipe
Q345 thermal expansion seamless steel pipe is widely used in bridges, vehicles, ships , construction, pressure vessels and other industries. Q345 heat-expandable seamless steel pipe will decrease its yield value as the thickness of the material increases. The size of the core head of the hot-expanded seamless steel pipe: the expanded diameter - 2 wall thicknesses + reduced wall (3% within 5 cm of the reduced diameter), if the steel pipe is exported , the steel pipe needs to be beveled, painted and capped. The product has low cost , high production efficiency and great market potential, and the demand is increasing every year. The main production base of Q345 thermal expansion seamless steel pipe is in Cangzhou, Hebei.
