Q:What's the difference between a rectangular tube and a rectangular steel tube?
No difference, but your name is different, rectangular steel pipe, but can be divided into seamless rectangular steel pipe and welded rectangular, these two, in the material will also have a difference, I do not know how to help you
Q:What is the production process of seamless steel tube?
The main production process for hot rolling seamless steel tube (the main inspection):Tube preparation and check delta to billet heating, heating, rolling, perforated pipe, steel pipe and heat treatment, diameter (minus) Delta to finished tube straightening, finishing and inspection of delta (nondestructive, physicochemical, Taiwan inspection and warehousing)
Q:What is the outer diameter and wall thickness of DN40 steel pipe?
DN40 pipe diameter 48.3mm diameter, allowable deviation of plus or minus 0.5mm it depends on what you have, the outside diameter of 45, there are other dimensions, you can see the manual
Q:What quota is reserved for buried DN20 steel pipe?
If it is reserved for embedded pipe pre buried steel waterproof casing, set of waterproof casing steel production and installation is to set the quota items, if the outdoor installation of welded steel pipe buried steel casing pre quota items, if it is a reserved hole, then there is no need to set the quota items.
Q:How much is the wall thickness standard of building 48?
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.
