||These kinds of packers are being used for partial repairs of damaged pipe- lines as well as for repairs of couplings in combina- tion with artificial resins and strengthening mate- rials ensuring repeated tightness and suitable static tightness.
||Represent the most cost- effective implementa- tion of packers. They are equipped with a fast cou- pling for filling and emp- tying and with two lifting eye bolts, which are in- stalled for attaching the rope in the process of in- serting, transporting and pulling out.
||Are used for repairing of pipes with smaller diam- eter, mostly of household installations. Packers are rounded on both sides so that the slip across the turns and the bends or the shift is much simpler.
||Packers intended for repair works under 45, 60 and 90 degree angles. They are made of spe- cial materials, which also enable 90 degree adjust- ment.
