The Difference Between Precision Steel Pipe And Seamless Steel Pipe
The difference between precision steel pipe and seamless steel pipe
Precision steel pipe is a kind of high precision steel pipe material after cold drawing or hot rolling treatment. It is mainly used for the production of pneumatic or hydraulic components, such as cylinders or cylinders, seamless steel pipe because of the non-oxide layer of the inner and outer walls of the precision steel pipe, which is subjected to high pressure without leakage, high precision, high finish, cold bending without deformation, flaring, Cylinders can be seamless pipes and also welded pipes. Precise steel chemical composition of carbon C, silicon Si, manganese Mn, sulfur S, phosphorus P, chromium Cr.
1, the main feature of seamless steel pipe is welded joints, can withstand greater pressure. The product can be very rough as cast or cold parts.
2, precision steel pipe is the product in recent years, mainly the hole, the outer wall size has strict tolerances and roughness.
Seamless steel pipe storage conditions
Choose the right venue and warehouse:
1) Storage of steel sites or warehouses, should be selected in a clean, clean place, away from the production of harmful gases or dust of the factories and mines. On the grounds to remove the weeds and all debris, to keep the steel clean;
2) in the warehouse shall not be with the acid, alkali, salt, seamless steel pipe cement and other materials with aggressive erosion of steel together. Different varieties of steel should be stacked separately to prevent confusion, to prevent contact corrosion;
3) large-scale steel, rail, humiliation plate, large diameter steel pipe, forgings, etc. can be open piled up;
4) small and medium-sized steel, wire rod, steel, medium diameter steel pipe, wire and wire rope, etc., can be stored in a well-ventilated shed, but must be on the mat;
5) some small steel, thin steel, steel, silicon steel, small diameter or thin-walled steel pipe, all kinds of cold-rolled, cold-drawn steel and high prices, seamless steel pipe easy to corrode the metal products can be stored;
6) the Treasury should be selected according to geographical conditions, the general use of ordinary closed warehouse, that is, a roof with walls, doors and windows tight, with a ventilation device warehouse;
7) Treasury requirements sunny day attention to ventilation, seamless steel pipe rain pay attention to close the moisture, often keep the appropriate storage environment.
