Product Description:

1Structure of Seamless Pipe : 

Seamless pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. Since the manufacturing process doesn't include  welding, seamless pipes are 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.

 

2‍‍Main Features of the Seamless Pipe :

• High manufacturing accuracy

• High strength

• Small inertia resistance

• Strong heat dissipation ability

• Good visual effect

• Reasonable price

Q:What's the difference between a rectangular tube and a rectangular steel tube?
No difference, but your name is different, rectangular steel pipe, but can be divided into seamless rectangular steel pipe and welded rectangular, these two, in the material will also have a difference, I do not know how to help you
Q:What's the use of steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. (
Q:How can seamless steel tubes be produced?
After extrusion to remove pipe sizing. The sizing machine passes through the cone bit and rotates into the steel embryo at high speed to form a steel tube. The inner diameter of the steel pipe is determined by the outside diameter and length of the sizing machine. When the steel tube is fixed, it enters the cooling tower and is cooled by spraying water. The steel tube is straightened after cooling. After straightening, the steel pipe is sent to the metal flaw detector (or water pressure experiment) by the conveyor belt for internal inspection. If there are cracks in the steel pipe, bubbles and other problems will be detected. Steel pipe quality inspection, but also through strict manual selection. After the quality inspection of the steel pipe, spray with the paint on the number, specifications, production batch number and so on. The crane is hoisted into the warehouse.
Q:Is the same specification seamless steel pipe more expensive than welded 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:Outside diameter 60, thickness 3.5 seamless steel tube, how many kilograms per meter?
Outside diameter 60mm, thickness 3.5mm seamless steel tube per metre weight: 4.88 kg. When calculating the theoretical weight (Kg/m) per metre of steel tube, the theoretical weight meter of the steel tube can be checked directly, and the formula formula can also be used.
Q:What's the material of Q325 steel pipe?
In terms of deoxidation methods, F, B, Z can be expressed as boiling steel, flat killed steel, killed steel and boiling steel. They are deoxidized steel, which is of poor plasticity and toughness. Welded joints made of this material are susceptible to cracks when subjected to dynamic loads. Should not work at low temperatures, sometimes hardening. In contrast, calming steel is excellent and uniform, with good plasticity and toughness.
Q:Fastener type steel pipe scaffold steel pipe wall thickness
The scaffolding steel pipe should be specified with the current national standard "GB/T13793" or "straight seam welded steel pipe welded steel pipe for low pressure liquid delivery" GB/T3091 Q235 ordinary steel pipe; steel pipe steel quality should meet the requirements of current national standard grade Q235 steel "carbon structural steel" in GB/T700
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:How to distinguish seamless pipe and welded pipe?
Most of the welded pipe is six meters, the pipe has obvious welding marks, and seamless pipe wall without welding marks
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.
