Q:A333gr6 steel pipe and domestic material of the same?
The SA333 standard in ASME (cryogenic seamless and welded nominal steel tubes), so A333-6 is a representation of the United States, followed by many countries.
Q:Heating system DN40 and DN32 welded steel pipe how to connect?
As for the flange connection: low pressure pipeline is generally not used in this way, can be divided into threaded flanges and flange welding flange, and the flange connecting pipes of different diameters, only the welded flange to diameter, said in a low pressure pipeline which has low pressure pipe connection make an unnecessary move, this is not much, but there are also people with non the standard flange for connecting different pipe diameter, which is not consistent with the technical specification!
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: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:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.Elbow is a common connecting pipe used in plumbing and heating. It is used for the connection of the bend of pipe, and is used to change the direction of pipe.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.
Q:What's the difference between seamless steel pipe and welded pipe?
Welded steel pipe, also known as welded pipe, is made of steel or strip after the formation of welding welded steel pipe, usually 6 meters in length. Welded steel pipe production technology is simple, high production efficiency, varieties and specifications, equipment investment is less, but the general strength is lower than seamless steel pipe.
Q:How to distinguish between steel pipe and spiral pipe material?
The alloy tube can be divided into: low alloy pipe, alloy pipe structure, high alloy tube, high strength tube. Bearing tube, heat resistant acid resistant stainless pipe, precision alloy (such as cutting alloy) pipe, high temperature alloy tube, etc..
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:What does "1.5" steel tube mean?
This is neither an outer diameter nor an inner diameter; it should be related to an English unit at the beginning of the pipeline development; it is usually used to describe galvanized steel pipes; it corresponds to the English units as follows:4, in charge of: 4/8 inches: DN15;• 6 in charge: 6/8 inches: DN20;• 1 inch tube: 1 inches: DN25;• inch two tubes: 1 and 1/4 inches: DN32;• inch half tube: 1 and 1/2 inches: DN40;- inch tube: 2 inches: DN50;• three inch tube: 3 inches: DN80• four inch tube: 4 inches: DN100;
