AR type drilling pipe

The AR type drilling pipe is a spiral pipe made of cold-rolled steel band and cut lengthwise, twisted to the right, with edges joined by bending away, creating reinforcement groove with a height of approx. 3 mm. The standard thickness of the lengthwise cut steel band is from 0,2 mm to 0,4 mm, and depends on the pipe diameter. Higher cut band thickness values are manufactured at special request.

AR-flex type drilling pipe

The AR-flex type drilling pipe is a spiral pipe made of cold-rolled steel band and cut lengthwise, twisted to the right, with edges joined by bending away, creating reinforcement groove with a height of approx. 3 mm.

The standard thickness of the lengthwise cut steel band is from 0,2 mm to 0,4 mm, and depends on the pipe diameter. Higher cut band thickness values are manufactured at special request.

AR-flex type drilling pipes are very stable, and compared to standard AR type drilling bands they can be bent without hassle to suit almost any radius. The minimum bend radius is 1,5x of the diameter. They are placed within formwork and secured against shifting, which could occur during concreting.

The minimum sale volume is three running metres, and this is the length of one piece of the AR-flex type drilling pipe.
