Q:Hot galvanized steel pipe for use?
1, galvanized layer uniformity: steel pipe sample in copper sulfate solution immersion 5 times continuously, must not turn red (copper plated)2, surface quality: galvanized steel pipe surface should be complete galvanized layer, must not have plating on the black spots and bubbles exist, allow little rough surface and local zinc tumor exists.3, galvanized layer weight: according to the requirements of the buyer, galvanized steel pipe can be used for zinc layer weight determination, its average value should be not less than 500g/ square meters, and any sample shall not be less than 480g/ square meters.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Rectangular fastener: used for the connection of two vertical intersecting steel tubes. It relies on the frictional force between the fastener and the steel tube to carry the load.Swivel fastener: used for connecting two steel tubes intersecting at any angle
Q:What place must use galvanized steel pipe to make lighting line?
Zinc plating has the advantages of uniform coating, strong adhesion, long service life and so on. The plating solution of galvanized steel matrix and melting the occurrence of complex physical and chemical reaction, the formation of the structure corrosion resistance of Zn Fe alloy layer closely. The alloy layer is integrated with the pure zinc layer and the steel pipe matrix. Therefore, corrosion resistance, submit amendmentsTherefore, under the water or the environment is more humid, it is recommended to use galvanized steel pipe to make the lighting pipe.
Q:What is the production process of seamless steel tube?
Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspectionThe production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
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: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:What quota should be installed for heating seamless steel pipe?
Seamless steel pipe having a hollow cross section, used as a conduit for conveying fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials.
Q:Can stainless steel pipes spray black paint?
Can. The surface roughening with a thick gauze, do not use ordinary paint intensity difference. With resin paint, paint can be
Q:45 and 316 which steel tubes are of high hardness?
This depends on the heat treatment state, if 45 steel, 314 stainless steel without heat treatment, 316 stainless steel hardness, if the heat treatment, that is 45 steel hardness.
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.
