Q:How can galvanized steel pipe be connected with stainless steel pipe?
Welding methods are used to connect. Because galvanized pipe is in fact carbon steel pipe, so galvanized pipe and stainless steel pipe welding, in fact, carbon steel and stainless steel welding, welding of dissimilar materials.
Q:Material of welded steel pipe
GB/T3091-1993 (galvanized steel pipe for low pressure fluid delivery). Mainly used to transport water, gas, air, oil and heating, hot water or steam, etc. generally lower pressure fluid and other use tube. Its representative material is Q235 grade a steel.
Q:What is an electric welded pipe (EFW)? Seek help!
According to the operation requirements of the electric welding machine, connect the lead wire and set up the proper welding parameter of the electric welding machine, which can be operated by manual or automatic two input methods.After checking, start the electric welding machine and enter the welding process. When the welding time is reached, the machine will automatically enter the cooling state.When the pipe completely removed after cooling, electric fusion welding machine.Cutting the pipe with the cutting tool of plastic pipe or fine toothed saw with cutting guide device, and making its end face perpendicular to the axis of pipe. Remove the edges of the edges with a knife, scrape the weld area in the pipe or spigot end and clean the weld area.Should use the special fixture as far as possible to secure the components to be connected, and the roundness of the pipe shall not exceed 1.5% of the outer diameter of the pipe, or it should be corrected on the corresponding fixture.
Q:What are the main types of steel pipe ah? How to judge which kind of steel pipe performance is better?
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square, flat) pipe.The welded pipe is rolled into the steel tubular to sew or spiral seam welded in the manufacturing method, and is divided into low pressure fluid delivery with welded steel pipe, spiral welded steel pipe, welded steel pipe, welded pipe roll etc.. Seamless steel pipe can be used in various industries, such as liquid, pneumatic, pipeline and gas pipeline. Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.Press materialSteel pipe according to the pipe material (ie steel) can be divided into: carbon tube and alloy tube, stainless steel tube.Carbon tube can be divided into ordinary carbon steel tube and high quality carbon structure tube.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:Seamless steel tube with the tube with what is the difference?
Seamless pipe can withstand ultra-high pressure, of course, its wall thickness will increase, which needs to be designed according to pressure requirements. It is generally used in high-pressure oil pipes, boiler tubes and other high temperature and high pressure equipment. There are also seamless tubes for structural purposes, depending on the design requirements.
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: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:Is the electric pipe used with steel pipe or PVC pipe?
When the electric wire pipe is laid, the steel pipe can be adopted, or the plastic pipe can be adopted, but the steel tube must not be used in the ceiling. The standard explanation is for rat bite.
Q:Are metal spiral tubes the same as metal bellows?
The spiral pipe is mainly used in the pipeline of petroleum and natural gas, and its specifications are indicated by outer diameter * wall thickness.
Q:What kind of argon arc welding wire is used for 16Mn steel pipe?
16Mn steel belongs to carbon manganese steel, the content of carbon is about 0.16%, and the yield point is equal to 343MPa (strength grade is 343MPa). 16Mn steel alloy content is less, good weldability, welding generally without preheating. But because the 16Mn steel hardened tendency is slightly larger than the low carbon steel, so at low temperatures (such as winter outdoor operations) or welding in high rigidity, large thickness of the structure, in order to prevent the cold crack, need to take measures to preheat.
