Q:What is the single length of galvanized steel pipe?
The single length of galvanized pipe is 6 meters. The length of galvanized seamless steel tube is uncertain, depending on the length of seamless steel tube.
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:How do you solder purple copper plate and steel tube?
The copper plate and the steel tube are brazed by brazing or argon arc welding.
Q:How is the steel pipe dance installed at home?
Perforated steel pipe, is very troublesome, need support to the roof and drilling in the room, the bottom with tripod frame fixed nail, and welding, installation is very troublesome;
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's the difference between straight steel pipe and seamless steel pipe?
Seamless steel pipe and welded pipe are separated because of different production process. Seamless steel tubes include hot rolling, cold rolling, cold drawing, and other rare, such as cold extrusion.
Q:Is there any difference between HFW steel pipe and ERW steel pipe?
High frequency welding uses the skin effect to concentrate the energy of the high frequency current on the surface of the workpiece, and uses the proximity effect to control the position and range of the high frequency current flow path. The speed of the current is very fast, it can in a short period of time will be adjacent to the edge of the steel plate heating, melting, and through the extrusion docking, each has its own advantages, but also each has its own shortcomings. Generally according to specific circumstances, specific analysis of specific choices.
Q:What materials are used in scaffolding pipes?
The bamboo scaffold board made of bamboo or bamboo.
Q:Theoretical weight of 25*25*1.5 square steel tubes
Square steel tube, referred to as square tube, also known as square tube, is a square pipe of a kind of name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube. The tube is then rolled into square tubes and cut to the required length, usually 50 pieces per package.
Q:What kinds of steel pipe are divided into?
According to the weld shape can be divided into longitudinal welded pipe and spiral welded pipeStraight welded pipe: the production process is simple, high production efficiency, low cost, rapid developmentSpiral welded pipe: strength ratio of longitudinal welded pipe is high, with a narrow billet production of large diameter pipe, also can use the blank production of the width of the same diameter of different pipe. But with the same length of straight pipe, weld length of 30~100%, and the production rate is low. Therefore, the smaller diameter pipe most used straight large diameter pipe welding, mostly using spiral welding.Dividedagain general welded pipe, galvanized pipe, blowing pipe, wire tube, pipe metric, roller tube, deep well pump, tube for automobile, transformer tube, welding, welding of thin-walled tube shaped tube and spiral welded pipe.General general pipe: pipe used for conveying the low-pressure fluid. Q195A, Q215A and Q235A made of steel. Also can be used for easy welding of mild steel. The other pipe to conduct water pressure, bending and flattening test, have certain requirements on the surface quality, usually the delivery length is 4-10m, often requires a fixed length (or size) of delivery. The specifications of welded pipe with nominal diameter (mm or inches) nominal diameter and different pipe wall thickness, according to the provisions of general steel and thicker steel two, steel pipe end is divided according to form of threaded and non threaded two.
