【 Requirements for finished products of profiled steel pipe 】：
1. High requirements for surface finish and bright tube for delivery;
2. Hardness has certain requirements;
3. Each product needs to be extruded.
【 Technical difficulties in manufacturing special shaped steel pipe 】：
1. The surface is difficult to be treated and easy to have oxide scale;
2. The hardness is difficult to grasp;
3. The product is easy to crack during extrusion, and the main reasons are as follows:
a) If the hardness is too high, the steel pipe is easy to crack;
b) There are small impurities in the steel which are cracked by extrusion;
Since all the materials purchased in the market are unqualified, Our company specially customizes 16Mn raw materials with less impurities from round steel plant to ensure the quality of finished steel pipe 。 After more than 4 years of cooperation with customers, no product quality problems, quality stability, exported to Europe and the United States.
Under the joint technical research of both parties, in order to avoid the subsequent heat treatment process of customers and achieve the purpose of saving materials for customers, the hardness requirements are added to the steel pipe technology of our company. In the end, it saves materials for customers and improves production efficiency, And for customers to reduce 10% - 15% of the overall cost.
