ERW Straight Seam Steel Pipe Production Line

ZQMC-114

Intorduction

Φ114 Pipe Welding Line is mainly used to weld round and square/ rectangular pipes.

This line utilizes roll forming to process steel strip into various shapes. It is also capable of squeezing weld seam into closed profile through high frequency induction heating to make profiles for various diameters and sizes.

This line uses double radius pass design for forming.

114 Parameters:

Advantage of the line:

Easy adjustment, good weld seam quality, rigid machine structure and easy operation and maintenance. Horizontal roll stand and vertical roll stand share the same quick-change base, which makes the roll can be take off from the drive shaft easier, and save more time. The forming stand arrangement of this line uses double radius pass design.

Designing guideline :

To improve the serviceability and productivity

To meet safety requirements of multi-product small-batch production

To improve the environment and safety in operation

To improve the stability of the product quality

To improve the yield of the line

To reduce cost of the equipment

Line composition:

1. Hydraulic coil loading car

    Coil loading car carries steel sheet coil and loads it onto uncoiler. It is capable of coil centering and toppling prevention;

2.  Hydraulic single end uncoiler

    Used to hold steel coil supplied by coil loading car and align it with the production line. Positive rotation during coil unpacking and passive rotation during line operation.

3.  Head unbender and leveler

    Roll type flattener consists of two rows of rolls of equal diameter. These rolls are arranged staggeredly at equal intervals. Upper rolls are installed on the upper stands. Drive rolls are powered by reducer via transmission shaft equipped with universal joint. Steel strip to be flattened passes between two rows of rolls, where they are flattened by repeated elastic and plastic bending.

4.  Cutter & butt welder

    Cutter & butt welder is used to joint the trailing end of foregoing strip with the leading end of the follow-up strip after cutting, so that to ensure continuous pipe making.

5.  Horizontal spiral accumulator

    The horizontal spiral accumulator is used for storing steel strip; it can ensure the continual production by feeding the strip into the welder continuously. 

6. Forming and sizing unit

    This unit mainly consists of strip feeding unit, forming and sizing horizontal/vertical rolls, weld seam guiding unit, welding machine frame, weld seam squeezing unit, deburring blade carrier, cooling jacket, correction unit, and drive transmission unit, etc.

7. Cooling device

    Length 6000 mm, cooling down weld seam by water rinsing.

8.  Electric control part and full line electric interlocking

9. Full line hydraulic system
