Here are thousands tons of scaffolds as construction, leasehold and road and bridge, because the steel's thickness is easy to be reduced for being rusted after suffering wind and rain during construction, and some parts are easy to bend during disassembly and transportation. There are 35 steel tubes per ton, and each steel tube can use more than RMB 3 Yuan one year, one hundred more than RMB 10 thousands Yuan, one thousand more than RMB 100 thousands Yuan. If painting the steel tube with rust, the paint is easy to fall off, which brings a big hidden trouble to safe. For most old bad steel tubes are still used together with new ones, it not only offend the construction requirements but also offend the rules of supervising department. The quantity of accidents happened in construction as the falling down of scaffold is countless. So, after the project is finished, alignment and de-rust must be carried out, and then paint them. It can save fund and prolong the use life, in order to reduce safe factor. However, the steel tube belongs to round end-face, so it is beyond people's ability. The machine is specially used for scaffold steel tube alignment rust removing. It has been very popular with the consumers since it was introduced to the market.

He steel tube alignment de-rust machine of Kangkun brand, the newest multi-patent, is divided into two working areas. During getting rid of rust, the steel tube is pushed automatically, and multi-brush hairs form two directions to eliminate. For 6 m of steel tube, it only takes 3 minutes. The alignment adopts hydraulic pressure equipment, and it can adjust big bend for 1 m one time, small bend for 10 cm. And it only takes 2 seconds to adjust move pivot according to the bend. Alignment and de-rust can be carried out at the same time, or separately.
