Water tightness of Joints and Pipes, Magnu Crete® - F; Magnu Crete ®-MRequirements of the Standard

IS 27 (May 2010), which is the official Standard (bind-ing Standard), specifies the requirements well con-cerning gaskets, the joints and water tightness of the pipes and the joints.The requirements contained in the Standard are as follows:1. All the pipes are required to have flexible joints – in-tegral gaskets, or separate gaskets supplied together with the pipes by the manufacturer of the pipes.2. All the connected pipes are required to be water tight (this requirement is applicable for all types of pipes, for water conveyors, drainage lines, sewage lines and other types).

3. The gaskets are required to be standard as speci-fied in the EN-681-1 Standard or IS 1124, part 2.The pipe manufacturer is required to specify the gas-kets for his pipes in his catalog, and to supply them together with the pipes. Testing of the water tightness of the pipes and joints should take place at the manufacturer’s factory, with 2 pipes joined together in the test device. The test procedure is described in IS 27 (EN1816 in Annex-E, which is part of the Standard).Test pressure is 100kPa. During the testing proce-dure shear force should be applied between the pipes as well as an angular deviation between them as specified in the Standard.

The Wolfman Company installs the most up-to-date and the widest integral gaskets in the Magnu Crete – F pipes.These gaskets ensure the best joint and water tightness of the pipe lines.The types of gaskets are:ANKER-2000-L made by the CORDES CompanyOr BL-T made by the DENSO Company

Magnu Crete – F(The gasket is integrated

in the bell section)

Magnu Crete – M(The gasket is fitted by

the contractor at the site)

To install the pipes at the contractor’s site, he should use lubricant of the Magnuslip® type,

which can be purchased from Wolfman.

Integral gasket in the “bell”DisqualifiedGasket is supplied separately

from the pipe

Please note:Magnu Crete - M pipes

must be purchased together with gaskets from the same manufacturer. Incompatibil-ity between the gasket and the pipe will cause defective functioning of the system or

pipe failure.

“Bent” Pipes Concrete pipes can be “bent” to an angle according to the requirements of the planner – a single bend to a maximum angle of 300.The length of a bent pipe of Ø80 and up: about 2.50 meters.The bent joints using the bell and spigot method are identical to those for concrete pipes. (Magnu Crete – F and Magnu Crete – M).It is possible to integrate bends with integral chambers and save on many rectangular chambers. While im-proving the flow of water.The strength of the bent pipes is according to the strength of the pipes along the line (class/type). And the water tightness is according to the water tightness of the pipes). Price according to agreement

The recommended uses for a concrete pipe with an HDPE inlinerPipes of this type are recommended for use in the fol-lowing situations:1. Main sewage lines of Ø800 mm or greater.2. Sewage lines in which especially aggressive waste-water flows.Why is use of a concrete pipe with an HDPE inliner recommended?Sewage lines and main sewage accumulators are ex-pensive projects that are performed once in dozens of years and their continued existence in serviceable con-dition is anticipated to last for an extensive period.Renovation and repair of main sewage lines is extreme-ly expensive, involves complex work and usually impos-sible because it is impossible to shut down the line.Replacement of a main sewage line is extremely ex-pensive and often impossible when referring to densely populated urban areas.

Use of concrete pipes with HDPE inliner, have the following attributes and advantages:1. Very high mechanical strength due to the concrete pipes.2. Excellent chemical durability due to the HDPE inliner.3. Excellent water tightness resulting from welding the inliners together between the pipes.4. Greater service life than any other line as aresult of a combination of the strength of the concrete with the excellent chemical durability of the HDPE inliner.Although the initial cost of the concrete pipe with the HDPE inliner is higher than that of a regular pipe, in the long run this will prove to be a most worthwhile invest-ment in economic and engineering terms.

Technical knowledge and backupThe Wolfman Company is associated, in this regard, with the Austrian Agru Company, which is a world lead-er in this field.The knowledge, experience and technological capabili-ty of the Agru Company is available to Wolfman for the purpose of implementing pipelines of this type in Israel.

Magnu Crete® – Liner (MGL)Concrete Pipes with HDPE Polyethylene Inliner

In pipes of Ø1250 and higher it is recommended to use a 5 mm thick liner.

Use of HDPE liner reduces the amount of rein-forcement as a result of the possibility to reduce the thickness of the concrete cover above the

reinforcement on the internal side.

Example of a Magnu Crete MGL (Liner) Pipe

Technical Data1. Magnu-Crete®-Liner (MGL) pipes are intended for sew-age lines in which high durability to aggressive wastewater as well as maximum watertightness is required.2. The inner liner (inliner) consists of High Density Polyethyl-ene (HDPE) manufactured by the Agru Company in Austria. The entire liner is covered with integral anchors ensuring ex-cellent anchoring to the concrete.3. The thickness of the liner is 3 mm or more according to the requirements of the customer/planner. For pipes with a diam-eter of 125 cm or more, a 5 mm thick liner is recommended.4. Connection of the pipes to each other is by welding the liners to each other after the pipes are installed in place.There is no need for an overlapping strip.5. Experienced welders from Wolfson, with appropriate ex-perience and certifications, must perform the welding of the liners to each other at the site. The welding shall only be by EXTRUDER .6. The concrete pipes have an integral embedded gasket. The gasket complies with Standards DIN 4060 and EN 681, applying to sewage.7. The class of pipes in terms of strength and environmental conditions are according to IS 27 (May 2010).
