Directory of companies by products - Poly-fusion welding of plastics
WITECH PLAST s.r.o.
Category Description
The principle of poly-fusion welding is contact welding of plastic pipes and fittings
,ie welded area is heated by contact with body nahrievacím . Welded parts are needed to fire the required welding temperature and the sliding tube and pipe sleeves nahrievacie on the size
,mounted on nahrievacom body. After the heating period
,the welded parts removed from nahrievacích sleeves and without mutual pootáčania inserted into each other. Areas nahrievacích sleeves are slightly conical to allow a combination of tube and pipe welding sufficient pressure. This is possible even at small axial forces develop sufficient thrust
,it is possible to hand- welding pipe diameters up to 63 mm DA . For larger diameters (up to DA 125 mm )
,mainly for reasons of accuracy and alignment
,it is appropriate to use welding equipment . In conjunction with the pipe fitting is necessary for a minimum period of cooling (about 30 s) fix welded parts
,the burden of service can be a first hour . after welding. Welding parameters
,i.e. time the heating
,sliding time period
,and resetting the tab indicated for each pipe
,and fittings .
