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:How to make the internal tooth of the steel pipe?
At present, in our country, 300MW or 600MW or more large capacity sub critical and supercritical thermal power boilers are designed or imported abroad. Membrane internal wall tubes are widely used in membrane water wall.
Q:Seamless steel pipe and welded pipe what is the difference?
The welded pipe is made directly from the stainless steel band by machine, and it is made of round steel or perforated by Guan Pi
Q:Can seamless steel pipe and ordinary steel pipe be welded?
If your project is a seamless steel pipe, so theoretically, you put the tube with connected is not used.But the actual engineering operation, design drawings will be put on the normal need to improve the requirements of the drawings to the actual requirements, so if is the need of seamless steel pipe, welded pipe in the end so can you see yourself.
Q:What is the production process of seamless steel tube?
The main production process for hot rolling seamless steel tube (the main inspection):Tube preparation and check delta to billet heating, heating, rolling, perforated pipe, steel pipe and heat treatment, diameter (minus) Delta to finished tube straightening, finishing and inspection of delta (nondestructive, physicochemical, Taiwan inspection and warehousing)
Q:Is there a weld on the outer wall of seamless steel tube?
Seamless steel pipe's inner wall, outer wall, section, cross section can not see the weld seam. Because seamless steel pipe is a molding product, no late roll pressure, welding and other processes. No section, inner wall, outer wall or section, as long as there is weld, it is not seamless steel tube. The inner wall can not see the outer wall of welding seam, but it can be seen that the weld products are fake or polished goods. Some products can not be seen without friction and have weld seams on the outside wall. They are seamless treated steel tubes and are polished goods. The price is much different from the real seamless steel tube. Some bad wounding, confusing concepts, earn illegal profits.
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:Difference between cold rolled steel pipe and common steel pipe
From the above point of view, the hot rolled steel pipe used in fluid transport, mechanical structure and other requirements of the size of the situation is not high, cold-rolled steel pipe used in precision instruments, hydraulic systems, pneumatic and other places demanding.
Q:How to establish a concrete-filled steel tubular column model in ANSYS?
A two unit model or a composite unit model can be adoptedTwo units are constructed of steel tubes and concreteA composite unit may be either a fiber element or a section conversion attribute
Q:How to identify stainless steel pipe and steel pipe?
Steel pipe according to the production method can be divided into two categories: seamless steel pipe and pipe joints, pipe joints as welded steel pipe.1. seamless steel tube according to the production methods can be divided into: hot-rolled seamless pipe, cold drawn tube, precision steel tube, heat expansion tube, cold spinning tube and extrusion tube.Seamless steel tubes are made of high quality carbon or alloy steel. They are hot-rolled and cold-rolled (drawn).Bundled steel pipe2. 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.
Q:What are the main aspects of precision steel tubes?
Products according to their application areas are divided into: automotive, precision machinery tubes; power plants, nuclear power tubes; titanium and titanium alloy tubes; chemical tubes; varieties include colored, black; seamless; welding; general and special-shaped
