1、Structure of Stainless Steel Welded Pipe ASTM A358/A312/A778 Description:

    Stainless steel welded pipe is actually a cover term, covering a wide range of alloy and making them suitable for different attributes that are used in a very wide and large numbers of different industries. Stainless steel pipe is resistant to erosion, highly flexible, powerful, easy to use, and can be done in distinct approaches, which means that more and more stainless steel was used as a construction material for large-scale, high impact buildings. It can be molded, rolling, and it can create amazing shapes to make it perfect, It is used as experimental buildings, The use of steel pipe welding of large stainless steel covers other examples.

Q:What does "SC50" steel pipe mean in civil engineering?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:How many meters per ton of steel tube?
Metric tons are metric units and China adopts metric system, so what we Chinese usually say "ton" means "metric ton", which can be regarded as "metric ton"1 metric tons (tonne/metric ton) = 1000 kg1 tons = 1000 kg1 kg = 1000 grams
Q:Is it good to buy a simple wardrobe or a steel pipe?
If the home place is big, buy Wooden, good-looking durable, if the place is small, buy cloth, easy to receive, mobile, tidy and cheap.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory.
Q:The difference between 12Cr1MoVG alloy steel tube and 15CrMo
15CrMo is a steel Pearlite Heat-resistant steel, has high heat resistance at high temperature (b = 440MPa) and antioxidant activity, and has certain ability of anti hydrogen corrosion. Because of the high content of Cr, C and other alloy elements in steel, the tendency of hardening of steel is obvious, and the weldability is poor.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
PVC pipeline use temperature is -5 to 90 degrees or so, according to the current market price of around 6000 yuan per ton, the price is cheap. Its corrosion resistance is good, can resist most of the acid and alkali, and unlike the steel pipe that is easy to rust, so in the construction of the upper and lower water pipes and other fields have gradually replaced the trend of steel pipe.
Q:How long is the seamless tube?
Welded pipe is generally 6912 meters fixed length, seamless pipe on the market in general non fixed foot, but usually more than 6 meters
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:Is the electric pipe used with steel pipe or PVC pipe?
Electric pipe laying is generally divided into the following circumstances:1) the explosion-proof area must be galvanized steel pipe and explosion proof flexible pipe (used for front end equipment connection);2) non explosion-proof area can use KBG pipe or PVC tube, the former is higher cost, but the installation is firm, the latter is low cost, easy to construction, and in the rain where it will not rust, but compared to the KBG pipe may be damaged.
