- Q:What are the advantages of PVC pipe and galvanized steel pipe?
- Galvanized steel pipe is also used, because some areas require the use of strength. Moreover, the iron and steel industry is a pillar industry, there are some unspoken rules in it.
- Q:How can seamless steel tubes be produced?
- Tube mill, round tube billet, heating, perforation, three roll cross rolling, rolling or extrusion, removal of pipe, sizing (or reducing diameter), cooling, straightening, water pressure test (or flaw detection), marking, storage, cold rolling and hot rolling. Generally cold rolling, because of high accuracy.
- Q:Seamless steel pipe is how to do it?
- Round tube has some limitations, such as in the plane bending conditions, the tube is better than square and rectangular tube bending strength, and some agricultural machinery skeleton, steel, wood furniture, commonly used square, rectangular tube. According to different purposes, other sections of special-shaped steel pipe are needed.
- Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
- 1.: Construction of the underground pipeline, levy more pumping, boiler hot water transportation etc..2., mechanical processing, bearing sets, processing machinery parts.
- Q:Heating system DN40 and DN32 welded steel pipe how to connect?
- Is the wire: also called pipe thread connection, the malleable steel pipe fittings, malleable iron is the thread connection using DN40X32 diameter hoop.
- Q:What is the difference between steel pipe and round steel?
- The middle of the steel pipe is hollow, and the round steel is solid. When compared with the solid steel such as round steel, the steel tube has the same flexural strength and torsion strengthLight weight, is an economic section of steel, widely used in the manufacture of structural and mechanical parts, such as oil drilling pipe, automobile transmission shaft, bicycle frame and steel scaffolding used in construction.
- Q:How can galvanized steel tubes be painted on the surface?
- Suitable for galvanized base material (antirust primer), epoxy zinc yellow primer (double component), epoxy ester zinc yellow primer.Pretreatment of galvanized sheet when brushing:1, conditional, you can zinc plating phosphating treatment, or first spray a layer of phosphating primer.2, or smooth zinc plating surface sweeping treatment.3, the galvanized workpiece, galvanized pipe surface with solvent (that is, epoxy zinc yellow primer, thinner) wipe, in order to remove the workpiece crude oil protective layer, and increase cleanliness.4, two-component epoxy zinc yellow primer: in strict accordance with the proportion of paint and curing agent paint, and aging 30 minutes later, modulation suitable construction viscosity, you can spray.One component epoxy ester primer: zinc yellow construction viscosity suitable to construction of modulation, the correct construction method.
- Q:Which is cheaper, angle iron or steel pipe?
- Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. Using steel pipe to manufacture road bridge can not only save steel, simplify construction, but also greatly reduce the area of coating protective layer, save investment and maintenance cost.
- Q:How to identify stainless steel pipe and steel pipe?
- Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
- Q:Seamless steel tube 89X4 meters, how heavy?
- The theoretical weight calculation formula of plain carbon steel and alloy steel seamless pipe:W=0.02466 (D-S) S, the density of steel fand 7.85kg/dmNote: weight per meter kg/m= (outer diameter wall thickness) * wall thickness *0.02466 units, mm: mmFor example, the seamless steel pipe with a diameter of 89*4 weight per meter:(89-4) *4*0.02466=8.384 kg / M.
