Document Type and Number:
Japanese Patent JP5326176
Kind Code:
B2
Abstract:
The present invention refers to a process and an apparatus for combination of steel tubes or pipes with plastic linings, in which steam is used as heat carrier to heat the steel tubes or pipes lined with linings. The apparatus comprises a multifunctional combining chamber, a multifunctional carriage for conveying tubes or pipes, an arrangement for steam circulating, which continuously supplies re-usable steam, a cooling and shaping arrangement and a controlling device. The steam circulating system comprises a furnace for re-heating the steam and means for supplying supplementing steam. The percentage of passing the qualification control is increased up to 99.9% by embodiment of the method and/or apparatus according to the present invention, while it is only 97% by a conventional apparatus, and the production capacity is increased by 15%. Thanks to the recovery and re-use of the steam in a circulating system, it will use only three tons of steam if the daily production is forty tons in a production line, and 405 RMB will be saved in a day. Thanks to the recovery and re-use of water in a circulating system, the water consumption for producing a ton steel and plastic combined tubes or pipes will be reduced by 8%. That means a remarkable economic and environmental value. The present invention will decrease the labor intensity of the workers and the cost that refers to the work time by 5%. The total cost for a ton tubes or pipes will be reduced by 10RMB.
