Product Description:

1Structure of Seamless Pipe : 

Seamless pipe is produced by drawing a solid billet over a piercing rod to create the hollow shell. As welding is not included in the manufacturing process , seamless pipes are stronger and more reliable.  

2‍‍Main Features of the Seamless Pipe :

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Great price

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:What type of steel pipe dance is used in general?
The steel pipe fittings used in the pipe dance are made of smooth surface material, usually chrome or polished by steel or iron.
Q:Is steel pipe made of profiles?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:What is hot rolled steel pipe? What is a cold drawn steel tube?
General use seamless steel tube: is with 10, 20, 30, 35, 45# and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other alloy steel hot-rolled or cold rolled. Seamless tubes made of low carbon steel, such as 10, 20, are mainly used for fluid delivery pipelines. 45. Seamless tubes made of medium carbon steel such as 40Cr, used for the manufacture of mechanical parts, such as parts of automobiles and tractors. General use of seamless steel pipe to ensure the strength and flattening test. Hot rolled steel tubes are delivered in hot rolling or heat treated conditions. Cold rolled in heat treated state.
Q:How to make the internal tooth of the steel pipe?
Cylindrical thread can be used, if the tube is too long, you may consider a short tube with thread, and then welded to the long tube. Taper thread is more difficult to use than ordinary vehicle, and the tap is generally considered. The tap can be clamped on the tailstock.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
Carbon steel is actually relative to alloy steel, mainly carbon content, and 20# seamless steel is carbon steel! In addition, there are stainless steel, stainless steel is considered a kind of alloy steel, but the processing is not the same, the performance is not the same, good looking outside!The description of the material in alloy steel is actually the content of the metal elements in the steel (usually the percentage number).
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
Seamless steel pipe: a pipe with a hollow cross section, used as a conduit for transporting fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What connections are there for concrete filled steel tubular column foundations?
Strengthening ring joint is a more common in the construction of steel pipe concrete column construction, it is to beam column connection through the upper and lower plate reinforcing ring bending force transmission way is through two to strengthen the uniform arrangement between the rings radial ribs and rib structure to connect with the ring the pipe wall at the top of the plate, so as to transfer the shear stress, so as to strengthen the thickness and improve the quality of connection engineering advantage. In the process of engineering construction, according to the construction principle of longitudinal reinforcement of Deng Qiang to control, so that the smaller width of not less than the replacement of the width of the connecting plate 70%, also need to be given due attention in the form of node selection
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:How many fasteners are there in a ton of steel tubes?
Steel tube (Steel pipe) production technology development began in the bicycle manufacturing industry, the rise of the early nineteenth Century during the oil development, the two world war ships, boilers, aircraft manufacturing, manufacturing of power boiler after the Second World War, the development of chemical industry of petroleum and natural gas drilling and transportation, will effectively promote the the yield and quality of varieties, the development of steel tube industry.
