PIPE PAINTING PLANT

PIPE COATING PLANT This plant was developed as new technique to provide against future request and need for coating on Pipe and C-shape steel. 1.The reason why steel manufacture set up this plant. To proof against rust and corrosion on surface of product during delivery after production. To solve problem which is caused during 1st base coating. A lot of still pipe manufacturers have been installing this plant. 2-1. the local distributor secure many kinds of product and deal it.   Deliver goods from steel pipe manufacturer.There is possibility to induce a flaw on product surface during transportation and by climatic influence ( rain, snow and frost etc..) Long-term stockBecause a distributor can not prevent rust or corrosion that is occurred on surface of product. When keep long-term, an inventory should be disposed for its scrap value. So the 1st base coating is required.   2-2. A requirement of customerBecause the first user who make new product with original pipe has to coat the surface, the  pipe is exposed in the air. In case of this process The company can be pronounced fine or detention by environmental law violation through mistake that pollute air. Worker lose his health by influence of poisonous ingredient that is contained in paint. Among general coating method,   a) with Bush or Roller Because coating film is thick, a consumption of paint and cost for coating are increased. The floor is contaminated working time is long personnel expense is increased b) Spray coating with air The paint dispersed in the air, polluter the circumstance ( a spouted paint spread about 400m ) even though a lot of quantity of paint was sprayed, it is about 15% that is coated on the surface of pipe, so it is also economical loss. worker can suffer damage to hazardous object. So the customer prefer to buy the pipe with 1st surface treatment for their economical.   Our plant’s advantage corresponds with management philosophy of steel manufacturer. High performance Economical efficiency Saving of resources Saving of energy Reduce the pollution of air and water Maintenance of performance for long time Improvement of working circumstance The pipe coating plant which has above several merits have been supplying to domestic companies from  5 ~ 6 years ago. In case of the company in developing country, they started to use this plant from 2004. Sales Merit Nowadays the pipe sales distributor and customer wants to get 1st coated pipe. And, as for manufacturer, they can sell the product with high quality and attractive price. If you do not have it, your agent may handle another supplier’s product. In korea, about 30 ~ 40% of steel pipe manufacturer already installed it. And a lot of importer of steel pipe from china also got it.   [ Equipment comparative table ] Difference of equipment possession and non- possession When you have the plant, you can take the above advantage.  Specially, you can prevent sliding accident which can be happen at general rust preventing and have productivity elevation because long-term storage is available in pipe management. Because the product with 1st coating is easy to use and convenient to store, the consumption will be increased.   [ Pipe plant cost ] plant amount : about \500,000,000.- (generally) Loaning interest for industrial investment : about 4%( local autonomy fund : about 3.5%) interest for \500,000,000.- for 1 year  : \48,000,000.-/year profit / cost : about 30% production 12,000 ton/year : \960,000,000.- x 30% = \288,000,000. created profit \288,000,000 - \48,000,000 (interest) = \24,000,000.-   [ Planning for Pipe coating plant ] This equipment will be designed and manufactured specially in elevation of reliability, stability and maintainability. We will try more and more for development of better installment. We appreciate your examination and advice about our plant.   [ Application ] This plant is applied to your product like pipe, C-shape steel painting and transfer equipment. ObjectThis plant is manufactured and installed for continuous working process of conveyor system of Pipe, C-shape steel cleaning, coating and drying. You can get energy curtailment effect by operating this plant with preventing paint loss and heat loss that happen during coating. Therefore, this plant make increase customer's purchase amount and enlarge production capacity by improvement of working environment, cost reduct and elevation of quality.   [ Configuration of Plant ]This plant is designed and installed to achieve preceding descriptions purpose with named “SPRAY PAINTING LINE FOR PIPE”. INLET CONVEYOR INLET CHAIN CONVEYOR NLET LIFTER POCKET FEEDING CHAIN CONVEYOR WALKING & KICKER   [ Estimation and problem solution of pipe coating plant ] It was designed to come forward in succession with washing and coating a round (or square) pipe that become charging consecutively by Roll conveyor. There are problems in manufacture, transportation and installation because the structure of this system is complex. Pretreatment à Washing ( cleaning ( with milling oil) : 5 ~ 10 sec., air blowder : 5 ~ 10 sec.)Moisture dry oven & coating dry oven  à M.F Heater. We lowered equipment price greatly by method such as upside. ( usual line : \3,000,000,000 ~ 4,000,000,000.-  , Developed plant : \500,000,000.-) Environmental problem about wastewater and air pollutionWe reduced displacement from coating booth by lower than acceptable level to solve problem about wastewater and air pollution. And we install the paint-withdrawal device to solve wastewater and air pollution problem. This solves environmental problem and reduced burden of environmental problem in future equipment planning. Cost reduction of Paint A) comparison of Paint cost reduction according to coating method Brush coatingCoating that do by brush is convenient to coat big product freely and it is advantage that unnecessary consumption of coating material does not exist. But, it is not suitable to a pipe for mass production. Air-spray coatingIt is easy to handle the air-spray coating and widely used because various shape and size can be coated and fine view is superior. But a paint is dispersed too much and coating efficiency is low. And the cost of equipment for mass production is expensive.So it make environment problem with dispersed paint. The consumption of paint is increased. Air-less spray coatingThis is the method which meet your need. The liquid in commonness and High-viscosity are atomized efficiently and the particle is thin relatively and uniform.Because air-less spray do not use air to be atomized, work-efficiency is high and waste of paint is decreased much. Electrical coloringThere are two ways to do color-coating by electric method, electrostatic coating. In this method,- coating thicknesses equal- surface gloss is excellent- coating is available by discharge of small quantity.But this is used for small product and the price of equipment is very expensive.   B) Cost reduction with equipmentWe got a patent of this plant which was developed for paint cost reduction and protecting environment. In current coating plant, the A/C tower is equipped behind paint boot. But, because a dispersed paint is radiated without filtering from paint booth, A/C tower can not prevent the air pollution and more than 70% of paint is wasted. So we developed the paint recycling system which can take 90% of paint from waste paint and save the paint cost.
