Q:Difference between seamless steel pipe and welded pipe
Welding pipes can be used in water pipelines, gas pipelines, heating pipes, electrical appliances, pipelines and so on.
Q:SC15 what does galvanized steel pipe look like?
DN15 galvanized pipe, nominal diameter of 15mm
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe, not seamless steel pipe, seamless steel pipe, welded seam, how can it be called seamless pipe?. Tell you a method: measurement of wall thickness, multi test several points, if each point, that is because it is cold drawn pipe, seamless pipe, hot rolling, wall thickness may% by sample.
Q:ASME seamless tube how to express, what is the form, I did not find on the ASME, thank God!
You can refer to the ASME B31.10, such as the requirements for the SA106GRB seamless steel tube outer diameter of 168.3 x 7.11, specifications can be marked as NPS6 SCH40 SMLS, the real mark should include pressure steel pipe factory name or trademark, and the material level, specifications, standards, wall number, batch number, pressure test (if any), NDE detection (if any)
Q:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
Q:Seamed steel pipe seamless steel pipe, carbon steel pipe, galvanized pipe, four how to distinguish between
Seamless steel tube processing technology:1.1 、 hot rolled seamless tubes are usually produced on automatic rolling mills. After checking and cleaning the surface defects, the solid tube is cut into the required length, centring on the end face of the tube blank, then sent to the heating furnace and punched on the piercer. At the same time, the hole rotates and advances continuously. Under the action of the roller and the plug, the inner cavity of the pipe blank is gradually formed, and the cavity is called the capillary. Sent to the automatic tube rolling mill on rolling. Finally, the thickness of the whole machine is the same, and the diameter of the sizing machine is determined to meet the specifications. It is an advanced method to produce seamless steel tube by continuous rolling mill.1.2, in order to obtain smaller size and better quality of seamless tube, cold rolling, cold drawing method must be used or combined. Cold rolling is usually carried out on a two roller mill, where the steel tube is rolled in the annular groove made of variable cross section, round hole groove and stationary conical head. Cold drawing is usually performed in single chain or double chain cold drawn machines from 0.5 to 100T.1.3, the extrusion method will soon heat the tube blank in the closed extrusion cylinder, the perforation bar and extrusion rod movement, so that extrusion parts from the smaller hole extrusion. This method can produce smaller diameter steel pipe.Seamless steel pipe use: mainly used to transport fluid pipeline or structural parts.The main use of steel pipe joints (steel) two welded together, so the price is cheap, widely used.
Q:Is the seamless steel pipe used in the market hot or cold drawn?
Seamless pipe hot rolling, cold rolling, cold drawn three kinds. Among them, the amount of hot rolling, the largest quantity, the price is relatively cheap. Precision, roughness, mechanical properties, cold drawn and cold rolled are better. Of course, the specific use of your requirements, not expensive
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
The urban water supply pipeline cleaning is a very necessary work, it can not only improve the transmission efficiency of pipeline to reduce energy consumption, but also to clear the pipeline dirt, remove two pollution, improve water quality, protect the people's physical and mental health.
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:20# seamless steel pipe and seamless steel pipe 20G what is the difference?
20G seamless steel tube is a high-pressure boiler tube. In addition to carbon content, 20G seamless steel tubes also have some trace elements that are more suitable for use as boiler pressure vessels. In addition, 20G also focuses on its physical performance. Such as bending, impact and tensile properties. 0G seamless steel tube is a kind of steel strip with hollow section and without seams. A 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.
