Q:How can galvanized steel pipe be connected with stainless steel pipe?
The method of non direct fusion is adopted, such as blue, silk head and movable joint
Q:How can galvanized steel tubes be painted on the surface?
The market is commonly used in alkyd iron red primer, iron red epoxy primer are not suitable for galvanized parts, otherwise it is easy to fall off. It is important to point out that the saponification of the galvanized sheet with alcohol, acid and paint will result in the failure of the coating and the damage of the original zinc coating.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Butt fastener: used for connecting two steel pipe jointsThin-walled stainless steel pipe, the national standard consists of three parts, respectively on the thin stainless steel pipe connection, the sealing ring of raw materials of various specifications of O type thin wall stainless steel pipe diameter and wall thickness of pipe and rubber have clear requirements, in order to ensure the quality of the whole pipeline, pipeline safety and guarantee system durability. The connection mode is clamp type and ring type.
Q:What is ND steel pipe?
ND steel 09CrCuSb steel is currently the most ideal "resistance to sulfuric acid dew point corrosion in steel (ND steel, ND steel, 09CrCuSb steel, 09CrCuSb steel), ND steel is widely used in the manufacture of economizer, served in the high sulfur content in flue gas of air preheater, evaporator and heat exchanger equipment for resist sulfur smoke gas dew point corrosion.
Q:Is the PVC tube a plastic tube or a plastic tube?.
It's plastic tubePolyvinyl chloride (Poly, Vinyl, Chloride, PVC)PVC is a VCM monomer (vinyl, chloride, monomer), in peroxide, azo compounds and other initiators;
Q:How to make the internal tooth of the steel pipe?
Compared with the ordinary light pipe, tube can effectively prevent the formation of steam film between the seal and the pipe wall, increase the light disturbance flow inside the tube, the tube wall temperature is more uniform, which can avoid the light pipe damage, and improve the heat transfer efficiency of boiler. The number of thread head of internal thread pipe is 4, 6 head and 8 head according to need. The main materials are 20G, SA210C, T2, T12, 12Cr1MoVG, 15CrMoG, T22, T23 and so on. China needs 2.5~3.0 tons per year of inner thread tube.
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.
Q:Is it good to buy a simple wardrobe or a steel pipe?
Therefore, the simple solid wood wardrobe and steel pipe wardrobe is good or bad, according to personal preferences to set, and that environmental protection seems to have grades, easy to crack
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
According to the metal processing performance, pipe size, quality requirements, as well as investment and benefits to choose different processing methods and corresponding auxiliary processes. The basic process of cold rolling of cold drawn pipe are: (1) tube feeding, the pipe material for hot-rolled finished or semi-finished tube, pipe extrusion pipe and welded pipe; (2) pipe material preparation, including inspection, bundling, pickling, cleaning, washing, drying, neutralization, grease and so on; (3) cold processing (cold or cold); (4) finished finishing finished including heat treatment, straightening, sampling, end cutting, inspection (manual inspection and various testing), pressure test, oiling, packaging and warehousing etc.. Different products are refined and the content varies.
Q:How seamless steel tube is formed?
Hot drawing or cold drawing. The so-called cold is the billet from the thick wall tube is not heated, oil lubrication, with a steel sleeve inside, gradually elongated. Hot drawing is to make the billet tube red, do such work, generally thick wall applicable.
