Q:What material is RHS in the steel tube?
SHS stands for thin-walled square steel tubes in the structure and represents the self ignition ceramic composite steel tube in the material
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized pipe for pipeline laying construction and transformation of lighting, power, telephone, fire protection system in the engineering (made of galvanized steel), for laying, laying can be laid in the dark, the wall can also be installed on the ceiling.
Q:There are multiple welded galvanized steel pipe outer diameter 108mm wall thickness 4mm length of 6 meters
Galvanized steel pipe is divided into cold galvanized steel pipe, hot galvanized steel pipe, cold galvanized steel pipe has been banned, and the latter is also advocated by the state for the moment, can be used. In 60s and 70s, developed countries began to develop new types of pipes, and galvanized pipes were banned. China's Ministry of construction and other four ministries also issued a civilization, indeed from two, 000 years since the galvanized pipe as a water supply pipe, the New District cold water pipe has rarely used galvanized pipe, and some of the hot water pipe is galvanized pipe. Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:What does GALV mean in a steel tube?
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:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
Galvanized steel pipe is a kind of antirust steel pipe, often used in relatively high water supply pipeline or hot water pipeline, the price is higher, can use for at least 30 years;PPR pipe is a kind of polypropylene plastic, which is commonly used in environmental protection plastic pipes, but only suitable for low temperature occasions. It is mainly used for water supply;
Q:What's the difference between hot-rolled seamless steel tube or cold-rolled seamless steel tube?
Hot rolled seamless tubes are divided into ordinary steel tubes, low and medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel pipes, oil cracking pipes, geological steel pipes and other steel pipes, etc..
Q:What is lined pipe?
There are inner pipe jacket, such as day, tube, etc.; there are outside the pipe painted, such as large-diameter water pipes. An internally coated steel pipe for corrosive medium fluids replaces the expensive stainless steel pipe.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
First, the surface of the steel pipe is treated by embroidery, which is more durable, not faster than the rapid oxidation, and will not form white rust on the steel tube;Two. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave convex part is protected;
Q:What is a tight steel tube?
JDG pipe is the replacement of traditional PVC and SC pipes and other traditional wire conduits. It is a breakthrough in the field of building electrical field using new materials and technologies. The JDG pipe adopts the cross connecting ground wire of galvanized steel pipe and thin-wall steel pipe, overcomes the defects of complicated construction and large construction loss of common metal pipe, and solves the problems of poor fire resistance and difficult grounding of PVC pipe. Because the JDG pipe material is more expensive than the ordinary pipe material, it is more used in the construction, such as comprehensive wiring, fire protection wiring and so on.
Q:45 and 316 which steel tubes are of high hardness?
No. 45 steel for high-quality carbon structural steel, the hardness is not high machining, used to make the template, mould studs, guide column, subject to heat treatment. 45 steel quenched and tempered hardness between HRC20~HRC30; 45 steel quenching hardness between HRC55~58, the limit value of up to HRC62.
