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:What does GALV mean in a steel tube?
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.
Q:What does "spiral welded steel pipe" DN325*10 mean?
Spiral welded steel pipe with nominal diameter of 325mm and wall thickness of 10mm
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:DN80 seamless steel tube, what is the standard thickness?
The DN80 specification is 89*6 seamless steel management formula = (outside diameter wall thickness) * wall thickness *0.02466= per meter weight
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.
Q:304 stainless steel tube with the diameter of 25*2-3 is what mean
The quality of the steel pipe should be in line with the national standard "stainless steel seamless pipe for fluid transportation" (GBT 14976-2012) requirements.
Q:Galvanized steel pipe DN100 and SC100
DN is the meaning of "bore", also expressed in water supply and drainageSC is welded steel pipe, generally GB tube, that is, thick walled steel pipe, look at the design requirementsMT refers to the wire tube, usually thin-walled tube, there are KBG and JDG
Q:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
Q:What steel pipes are buried for outdoor heating pipes? Seamless or welded tube? Are there any rules for specific countries? Can use the seamed tube?
Where outdoor heating pipes are buried, what steel pipe shall be referenced by the 11.1.2 code for installation of outdoor piping?:This chapter applies to the quality inspection and acceptance of the outdoor heating pipe network installation of the plant and the civil building group (residential area) with the saturation steam pressure not greater than 0.7MPa, and the hot water temperature not exceeding 130 degrees celsius.
