Structure of spiral welded pipe mill Description

 

The steel coils are unfolded and leveled by the millequipment. And they are sent to the forming machine in a certain angle.Supplemented by a certain angle, the continual pipes are formed in theprinciple of three-roll rolling machine. Continual spiral welding is welded bysubmerged-arc welding machine.

 

 

Main Features of spiral welded pipe mill Description

 

According to the different function of our products,the spiral welded pipe mills are divides in to API standard model, nationalstandard model and special purpose model. API standard model mainly producesthe delivery pipe with petroleum or natural gas (long distance).the materialand quality of the steel pipe need to be very good. The requirements for millequipment and testing equipment also are very high. National standard modelproduces the pipe used for short distance delivery of natural gas or water, thepipeline construction in the city, the structure pipe, column pipe and so on.The requirements for the material and quality of the steel also are very high,second only to that of API standard. Special purpose mill is used for somespecial purposes. For example, our company developed the special 60214 mill aiming at the function of petroleum filter.

The specification of our products is fromΦ9 0 toΦ3500.The thickness of the wall is from 1mmto 25.4mm. The materialof our products is from Q235 to X80. Besides, special material such as thestainless steel is included. All of them cover all the mills.

Q:Material and equipment for roll forming process
Rolling molding is usually through upsetting a blank cold heading machine, thread rolling machine rolling after processed. The equipment for thread rolling and rolling forming includes various reciprocating flat rolling machines, planetary wire rolling machines, two cylindrical roller spinning machines and three cylindrical roller spinning machines.
Q:Improvement in rolling forming process
Can not meet the slender rod, thin-walled tubes and other rigid parts of the processing.
Q:What is rolling forming processing?
Ironing the surface of the workpiece with a raised micro wave crest to fill the concave micro troughs, thus changing the distribution of the peaks on the surface, and obtaining smaller surface roughness values.
Q:What kind of material and what heat treatment are used for pressing roller (molding, feeding, cutting force, heavy load, heavy load) of sheet steel rolling machine?
Generally speaking, to consider the use of rollers in the requirements, including: 1., good wear resistance, 2. toughness, 3., high hardness, 4. hardened layer (easy to wear after repeated repair)
Q:What is the surface rolling forming machine process?
Different from cutting, mirror rolling is a kind of plastic processing. Not only is the rolling workpiece surface roughness moment can reach Ry0.1-0.8 m, and the wear resistance of the surface hardening process has been improved at the same time fatigue strength also increased 30% advantages in cutting can not get.
Q:Introduction of roll forming process
With the progress of technology and the development of production, more and more attention has been paid to the roll forming process.
Q:Process mould for rolling forming process
Rolling forming is more complicated and requires higher than rolling thread. The die design is based on the different shapes of the workpiece, the design of the rolling plate into a cross section or a few sections, can use synchronous type; also can use grading type.
Q:A roll forming machine, rolling out of the length is always not up to a fixed size, not too small, that is, more than that, what is the cause?
Maybe there is something wrong with that roller. It rolls out of the wrong angle and the size will be out of order.
