Sealing ring (10) for sealing an annular gap between a concrete pipe sleeve (44) and a concrete pipe in a pointed end (48), wherein the sealing ring (10) a radial outer holding part (14) for connecting of the sealing ring (10) in the concrete, a radial, inner sealing member (16...
The vulcanised edges shield the sealing joint against aggressive attack from within and from ground water from outside. The jacket of the thrust collar engages the inner pockets (9), which become clamped flat in their inserted condition.HOEFIG, GEORG, MOENCHENGLADBACH, DE...
The water which runs or sprays out is collected to concentrated points and led off through hoses or pipes. In this work immediate-setting spray concrete must be used. However, the high content of accelerating additives in the concrete together with the presence of water gives this spray ...
A method for sealing boreholes in the earth and particularly around well casings extending into boreholes in the earth comprises the placement of a plurality of discrete, liquid-absorbing annular sealing elements or disks formed of relatively dry, solid, particulate or granular liquid-swellable clay...
3.Pu foam is widely used in sealing around doors, windows,pipes,indoor fittings or any other applications in construction. 4.Provides an excellent bond to lumber,plywood,concrete,metals,masonry and other substrates. Applications Way to apply: ...
Applications around plastic pipe penetrations are limited in diameter to DN 50 (2″) cold water and DN 25 (1″) for hot water. The high potential swelling pressure of SwellTape may result in pipe deformation. Larger diameters can be achieved with strong metal and cast iron pipes. ...
The ring has furrows 10, increasing the surface area in contact with the concrete and consists of elastomeric material having a shore hardness between 30 and 45. The pipe may be made of plastics.ALEXANDER SVEC
The sealing device (10) is attached to the outer surface (5) at the edge (6) of one of the pipes (1). It has an inclined front segment (11) made of a slightly more rigid elastic material in order to be easily inserted into the opposite pipe (2) end without being accidentally ...
The earthenware or concrete pipe (14) is fitted in the enlarged end (9) of the pipe (10) and the joint is sealed by the lips (1, 2) of the sealing ring. The outer pipe is provided with a shallow groove (8) to receive the sealing ring which is V shaped in its free condition....
1. The method of preventing entry of ground water into a sewage system through joints between adjacently interconnected large diameter tubular elements thereof comprising: (a) placing an elastomeric band about a first one of the elements prior to its interconnection with the adjacent element, ...
