Product Description:

1Structure of Carbon Steel Line Pipes with Various Standard: 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

Q:What is the difference between seamless steel pipe and welded pipe?
The main molding process is different. Ordinary steel pipes, such as tap water pipes, are usually welded by bending flat plates, and you can find a seam on it;
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN250 is the nominal diameter, the outer diameter of the steel pipe is 273mm, the thickness is above 6.5mm.
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:Seamless steel pipe and welded pipe what is the difference?
Seamless steel pipe is made of solid round tubes and perforated without gaps. The welded pipe is made of steel or strip after welding and has a slit. Generally seamless pipe can be greater pressure on the city.
Q:What does the diameter of a steel pipe project mean?
Generally, the diameter of steel pipe has three common diameters: outer diameter, inner diameter and nominal diameter.The first two are well understood.Nominal diameter refers to the national standard to specify the general diameter of a certain national standard pipe. It is only a model representation. It is neither outer diameter nor inner diameter.
Q:Stainless steel tube, also known as why tube?
According to the end of the pipe can be divided into light pipe and wire tubeThe tube can be divided into ordinary tube and special thread tube
Q:Are steel tubes and round steel in weight or length when purchased?
The price must be measured by weight, and the length, volume and other specifications should be entered
Q:What's the difference between steel pipe and pipe fittings?
Pipe fittings: parts that connect pipes to pipes. According to the connection method can be divided into socket type pipe fittings, threaded fittings, flange pipe fittings and welding pipe fittings four kinds. Multipurpose; made of the same material as pipes. Elbow (elbow), flange, three pipe and four pipe (crosshead) and reducer (reducer) etc.. Elbow for pipeline corner; flange for the pipe and pipe interconnected parts, connected to the pipe end, three pipe for three pipe collection; four pipe for four tubes together place; for two pipes of different diameters connected to different diameter pipe.
Q:What quota should be installed for heating seamless steel pipe?
Should be in low carbon steel welding installation set industrial pipeline engineering quota, material to input the name and type of seamless steel pipe specifications and price; according to the description of the contents of related items can be set.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
The 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.
