Q:What are the advantages of PVC pipe and galvanized steel pipe?
The steel plastic composite pipe is a product made of two different materials, steel and plastic, and the coefficient of linear expansion between them is quite different. The company is using a new plastic special plastic steel plastic composite pipe company and Nanjing University jointly developed, the polyethylene matrix, adding more than twenty kinds of new materials inside, greatly reduce the plastic coefficient of linear expansion, so as to ensure the steel and plastic composite materials in the reliability of the.
Q:Difference and application of seamless hot rolled pipe and cold drawn pipe in seamless steel tube
purpose2.1 seamless tubes are widely used. General purpose seamless tubes are rolled from plain carbon structural steel, low-alloy structural steel or alloy structural steel, with the most output and are used primarily as pipes or structural parts for conveying fluids2.2, divided into three kinds according to the supply of different uses: the supply of a, according to the chemical composition and mechanical properties; the supply of B, according to the mechanical properties; the supply of C, according to the hydraulic pressure test. According to a, the B class steel supply, such as for under fluid pressure, but also to the pressure test.2.3. Seamless tubes for special purposes include seamless tubes for boilers, seamless tubes for geology, and seamless pipes for petroleum use
Q:Which is better, galvanized steel pipe or stainless steel?
Stainless steel is good.Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
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:How are steel tubes represented?
If it is seamless steel pipe, welded steel pipe, the method of expression is: nominal diameter refers to the outer diameter (diameter * wall thickness). The unit is mm. [for example, seamless steel tubes of phi 32 * 3. It means that the nominal diameter (outside diameter) is seamless steel pipe of phi 32mm and wall thickness 3mm.
Q:What's the material of Q325 steel pipe?
Q235 refers to the material yield stress of 235MPa carbon steel, because of its low price, good machining and welding performance, it is generally used for welding structural parts. Of course, the unimportant parts can be used for it.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
Previously used steel pipe GB 51*3.0mm, the latest national standard JGJ130-2001 stipulates that the use of steel pipe for construction projects need to be 48*3.5mm specifications, the wall thickness should be 3.5mm square for qualified products.
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: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:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless steel tube is a kind of steel strip with hollow section and without seams.
