Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
After the use of full scaffolding, more than 3.6 meters of interior wall decoration is no longer calculated decorative scaffolding, and the interior wall of the scaffolding is still in accordance with the provisions of the scaffolding.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
Hot rolling is relative to cold rolling, cold rolling is performed under recrystallization temperature, while hot rolling is rolling above recrystallization temperature.
Q:Difference between cold rolled steel pipe and common steel pipe
1, from the dimension accuracy above, cold-rolled steel pipe size is good, high precision2. from the outward appearance, the surface of cold-rolled steel pipe is bright, and the surface of hot rolled steel pipe has obvious oxide skin or red rust
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Different materials, cast iron, steel seamless steel pipe; the different production process, cast iron is hot metal casting, steel rolling mill of seamless steel tube is through processing, different performance indexes, ductile iron diameter, wall thickness, crisp texture, relatively heavy, can be made of seamless steel pipe diameter is very small, the wall is very thin, good toughness, light. Cast iron, cheap, but the bottom of the strength, can only be used in low pressure occasions.
Q:How can seamless steel tubes be produced?
The material of rolling seamless tube is round tube blank, and the billet is processed by cutting machine to grow about 1 meters, and sent to the furnace by conveyor belt. The billets are heated into a furnace and the temperature is about 1200 degrees celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. When the round billet is released, it should be punched through the pressure piercer. The most common punching machine is a cone roll piercer, which has high production efficiency, good product quality, large perforation and expanding diameter, and can be used in various steel grades. After the perforation, the round tube blank has been successively rolled, rolled or squeezed by three rollers.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Seamless steel tube processing technology:1.1 、 hot rolled seamless tubes are usually produced on automatic rolling mills. After checking and cleaning the surface defects, the solid tube is cut into the required length, centring on the end face of the tube blank, then sent to the heating furnace and punched on the piercer. At the same time, the hole rotates and advances continuously. Under the action of the roller and the plug, the inner cavity of the pipe blank is gradually formed, and the cavity is called the capillary. Sent to the automatic tube rolling mill on rolling. Finally, the thickness of the whole machine is the same, and the diameter of the sizing machine is determined to meet the specifications. It is an advanced method to produce seamless steel tube by continuous rolling mill.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold rolling is usually carried out on a two roller mill, where the steel tube is rolled in the annular groove made of variable cross section, round hole groove and stationary conical head. Cold drawing is usually performed in single chain or double chain cold drawn machines from 0.5 to 100T.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller hole extrusion. This method can produce smaller diameter steel pipe.Seamless steel pipe use: mainly used to transport fluid pipeline or structural parts.The main use of steel pipe joints (steel) two welded together, so the price is cheap, widely used.
Q:Seamless steel pipe is how to do it?
Probably with 10, 20, 30, 35, 45 and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other composite steel hot-rolled or cold rolled.
Q:What materials are used in scaffolding pipes?
The bamboo scaffold board made of bamboo or bamboo.
Q:Why seamless steel pipe called seamless steel pipe?
Seamless is relative to welded steel pipe, because welded steel pipe is welded with steel strip, seamless steel pipe is made of whole round steel empty, no welding seam.
