The main characteristic of seamless steel pipe is no welding seam, can withstand higher pressure. It make the most of advantage of the micro structural material state for a physical view. The straightening process is generally used to eliminate the longitudinal bending and the roundness error of the rolled seamless steel tube. Plug Scores is the Internal longitudinal grooves occurring in seamless tube, usually caused by hard pieces of metal adhering to the high-mill plug.
Seamless steel tube is lighter and an economic cross-section steel that compared to round bar and other solid steel, in the case of same torsional bending strength, widely used in the manufacture of structural parts and mechanical parts, such as drill pipe, automotive drive shafts and other construction.
Precision steel tubes products emerged in recent years, mainly in the hole, bore, outer dimensions have tight tolerances and roughness. Precision steel tube is a kind of steel material with high-precision cold drawn or hot rolled processing. Because it’s inside and outside the wall without oxide, high pressure without leakage, high precision, high finish, cold deformation, flaring, flattening crack-free, so it can be used to produce pneumatic or hydraulic components of products. It has high dimensional accuracy, up to +/-0.03mm. Customers do not need processing can be used directly but for ordinary seamless steel tube, customers need to relathe polishing and other processing. The chemical composition of precision seamless steel tubes are C, Si, Mn, S, P, Cr.
How to Protect Seamless Steel Tubes?
Only in line with our operating needs of the product, play the advantages and value to the greatest extent in the operating environment and transport. In order to ensure long-term use, the production and development of steel, they are through many upgrades and improvements, such as seamless steel tube, galvanized steel pipe, are one of the more common types.
Seamless steel pipe can be suitable for the application of the places and areas, there are intuitive distinctions and differences in the future construction and storage, the future construction and storage, how to protect the seamless steel pipe?
The main production and composition of materials, that is, metal elements prevent long-term and environmental contact, leading to the emergence of corrosion problems, in the purchase and storage process should be careful.
Note: The cost of high and nowadays inflationary pressures, short-term seamless steel tube lower prices the probability of small, high price trend will continue. What are you waiting for?
