The current market conditions: high and low temperature the scaffolding tube through the open-air humidity and wind and rain erosion lead to rusting wall thinning and transportation, demolition, construction bent and flattened shape. 6 m tube daily minimum loss of 1 cent a year up to more than $ 3. One ton of steel pipe 40 annual consumption of more than 100 yuan, one thousand tons tube at least a year more than 12 million natural wastage. As we all know, the useful life of the steel pipe in 3-5 years, cycle repair up to 10 years. However, the circular end face with artificial leveraged pressure straight, not only damage the steel pipe but powerless, rusted sewage painting, easy to fall off and life is short. Years old dilapidated steel pipe dismay updates and improvise, to bring great risks to safety. Construction scaffolding collapse accident happened quite frequently, project supervision departments are not allowed by the advent of utility model patents, from incalculable social and economic benefits. Market dynamics: the market several Ratcheting forced straightening rust and one-time painting models, the price is as high as 2-3 million. However, according to the user experience, due to the size of the uneven curvature and can not enter or ineffective, especially slightly flattened steel tube simply can not be straightened, repeated cross-sectional transverse support short-effective waste greatly. Standard 48mm pipe wall thickness of 3.5mm. But the majority was less than 3mm, after mandatory rust tune straight local protruding parts of the drawbacks of chip damage. Wall thinning or by recurrent use and bump at the the tube card unfit and cause anti-stress. Tensile strength, support efforts to greatly reduce, increase insecurity often comes from the weak links and distorted, broken off. For safety and cost savings, pipe repair, extend the life of the weight of the steel pipe unit holders when the Service. Last five patents. Workspace of a machine two, three functions can be used simultaneously but also cross each other or separately jobs. Be adjusted individually straight hydraulic device, a dedicated 48mm frame tube repair, regardless of the medium and large hard bend, according to one steel pipe rebound coefficient meters to complete a one-time only 2 seconds, and can be partially restore hard bends and slightly flattened shape . 1-6 m tube can be adjusted directly. Rust by 30 damping wire rope brush surrounded by steel pipe, rust, ash can be clean and no damage to steel pipe. 2-6 m steel pipe alone rust, and paint at the same time a one-time auto-complete, 6 m steel pipe for only 50 seconds. Painting outside diameter range of 30-58mm. Other model wire rope bristles can not shock absorption and ineffective and injury steel and low efficiency drawbacks. To follow up automatic painting device, the implementation of the paint splash, do not waste paint uniform level without dripping, etc.. Solve the artificial spray, brush paint uneven and low efficiency. Unique new models, the only wearing parts bristles can be made, you can use the old wire rope diameter 14mm toothless saw cutting 100mm welding baking can be. Thrusting brushes, adjustment and simple cleaning. Work is completed, the valve is released, leftover paint recycling drums is very convenient.
