Square Tube Mill Details Images:
Forming Section
Function: to form the steel strips into a round shape and ready to be welded.
Advantage:
>Advanced forming technical
>One-stage molding platform
>Reliable quality gearbox
>Siemens Beide motor
Welding Section
Function: To weld the edges of the steel strips together by H.F. Welder (the H.F. Welder is not included).
Forming & Sizing Mill
Function: After welding, the pipes are almost the round shape, but it still needs to be modified into a regular round shape.
Initial Straightening Machine
Function: Another name is Turks head. It is used to rough-straighten the welded steel tube. It consists of two four-roller straightening machines, with its head able to revolve and move horizontally. It utilizes three-point method to straighten steel tube.
Square Tube Mill Auxiliary Machines:
Customers can trust us to buy the auxiliary machines. Our choice of suppliers for the auxiliary parts is made after 22 years of experience.
Un-coiler
Function: Used for supporting strip steel coil and open it as strip steel so as to make preparation for the pipe forming process.
Shearing butt welding
2 Types: Automatic & Manual
Function: Shear & end welder parallel cuts the head of the strip coming out of uncoiler and the tail of the strip steel going into the accumulator, and weld them together to form a smooth and continuous line of strip steel.
Strip Accumulator
Function: Accumulator is used to accumulate strip steel from uncoiler and provide strip steel to forming unit. It leaves time for the shear & end welder for strip welding and stores certain amount of strip for continuous forming.
Solid State High Frequency Welder
Function: The welder is used for welding edge heating with high-frequency heating device. The whole set of solid-state H.F welder comprises of rectifying cabinet, inverter, output cabinet, connecting optical fiber, closed loop water cooling system, central operator console, and mechanical adjustment device.
Saw Cutting System
Function: Flying saw is used to cut tube during static and motion status in continuously production into desired length.
Straightening Machine
Function:Straightening machine is a finishing equipment for the high-frequency straight seam welded pipe production line, which is used to straighten the steel pipe to eliminate the stress and bending after the steel pipe forming and welding.
Automatic Stacking and Packing Machine
Function: Electrical control using PLC control, touch screen, to achieve human-computer dialogue, manual, automatic between the free conversion.
Company Introduction
FAQ:
Q:Are you manufacturer?
A:Yes,we are manufacturer. We have 4 factories ( Machining,
Assembling, Heat treatment, and
Moulding ). We also have our own R&D department. Welcome to
visit us.
Q:What kind of payment term do you do?
A: We do T/T and L/C.
Q:What info do you need before giving me the price and proposal?
A: Since we design individual machine based on our customer's
requirement, we need your desired
products' basic dimension, including all the pipe diameter(or tube length), thickness range , usage,
raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A:Contact us immediately ,we provide free consultant for pre-sales
service .Also we can help you
solve the raw material (steel coil) purchase, worker training,
international market price, and more.
Q:How do you do QA?
A:We have special team to do strict QA,this is one of our
strengths:
(1)Every gear box will be tested for 8 hours with oil inside to
guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its in the range of
tolerance critical parts will be
inspected for all dimensions.
Q:Why I should choose you? what are the differences between you and
other Chinese suppliers?
A:We are concentrate on pipe making machines for more than 20
years. We have constructed many
steady trading partners in Asia,Africa, middle east, Europe, and South America throughout the years.
Our innovative designed production line and each single unit of the production line are not only
economical but also practical.
