1. Feature of steel barrel

steel barrel is manufactured from high-tensile crack-tested basic material in a special process, and are only stamped and released for dispatch after final ultrasonic testing.

Each individual wedge segment is examined for exact tooth shape by computer cameras.

In this way, we ensure the highest industrial safety and long service life of the anchor components.

2. General

These steel barrel is suitable for applications requiring prestressing force like mines, specification include KM15,KM18 and KM22.

Manufacturing standard GB/T14370-2007 and MT/T942-2005.

3. Technical performance

KM15 steel barrel can anchor 15.24mm and 15.7mm pc strand with strength 1860MPa, KM18 steel barrel can anchor 17.8mm and 18mm pc strand with strength 1860MPa, KM22 steel barrel can anchor 21.8mm and 22mm pc strand with strenth 1860MPa. Anchor efficiency more than 0.95 and total elongation more than 2%.

4. Working principle

Each set steel barrel consists of an anchor ring, and a pair of clips. There is a conical hole in middle of anchor ring, through which steel strand shall penetrate in advance during operation, and then clips shall be installed into this hole and fix the steel strand. Putting the jack in place, and start the oil pump to transfer oil. The jack will pull the steel strand towards outside. In this way, steel strand is anchored due to wedging effect.
