- Q:How can seamless steel tubes be produced?
- Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
- Q:Can galvanized steel tubes simmer?
- I make the steel pipe, galvanized pipe and water conveying pipe material is the same, can be bent, specific to what to look at the furnace, can refer to a single material
- Q:How big is the seamless steel tube of DN50?
- DN refers to the nominal diameter, the outer diameter is 60.3mm
- Q:How can galvanized steel pipe be connected with stainless steel pipe?
- Attention should be paid to the zinc coating at the side of the groove before welding. It is OK to brush silver powder after welding. There is a lot of information about the welding of carbon steel and stainless steel. Just check it online.
- Q:How seamless steel tube is formed?
- Seamless steel tubes are formed by cold drawing and hot rolling.
- Q:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
- Other commonly used theoretical weight formulas per metre:Thread steel (Kg/m):W=0.00617 * D * D, D - sectional diameter (mm)Fang Gang (Kg/m):W=0.00785 * a * a, a - edge width (mm)Flat steel (kg/m):W= 0.00785 * b * D, B -- edge width (mm) d - thickness (mm)Round steel rod (kg/m),:W= 0.006165 * D * D, D - diameter (mm)
- Q:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
- The difference is: 20# ordinary steel seamless steel pipe. 20G is the type of steel for high pressure boiler tubes.
- Q:Is there a weld on the outer wall of seamless steel tube?
- Seamless steel pipe, not seamless steel pipe, seamless steel pipe, welded seam, how can it be called seamless pipe?. Tell you a method: measurement of wall thickness, multi test several points, if each point, that is because it is cold drawn pipe, seamless pipe, hot rolling, wall thickness may% by sample.
- Q:What's the difference between hot dip galvanizing and cold galvanizing? Which kind of galvanizing method is good?
- Cold galvanizing refers to the zinc plating, the coating is thinner, corrosion resistance is slightly worse, variable color. Environmental pollution.Hot dip galvanized by molten zinc ingots, the coating thickness can be adjusted, good corrosion resistance, and subsequent passivation, can be used for outdoor rust, long service life, some up to 20 years.
- Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
- Rectangular fastener: used for the connection of two vertical intersecting steel tubes. It relies on the frictional force between the fastener and the steel tube to carry the load.Swivel fastener: used for connecting two steel tubes intersecting at any angle
