General information: This type of mechanical pipe joint is used in those cases where there is a high tensile load on the pipe joints, as well as for pulling the pipeline system out of the Ductile Iron Pipes in the case (inside another pipeline system), ideally suited for installation over loose soil or marshy land where one cannot provide anchor blocks at tee points or bends etc. The bellows spigot of this type of pipe has an annular collar to facilitate the gripping of special hook bolts that fix the socket connections and the smooth end of the pipe. The smooth end of the pipe has a round metal gland that has an L-shape and a sufficient number of bolt holes. The bell of the connecting pipe does not have any channel or sideways, but at the same time the distance between the wall of the bell and the smooth end of the pipe is sufficient for the EPDM seal set which causes a 100% tightness of the joint.
Main technical features:
- Pressure class in accordance with EN 545:2010 and ISO 2531:2009.
- External coating in zinc- aluminum alloy (400 g/m2) applied by metallization and watery epoxy paint certified to be in contact with water intended for human use.
- Internal lining in cement mortar blast furnace sulfate-resistant in accordance with EN 545 and ISO 4179
- Pipes are designed in such a way that individual pipes are connected using the lock system to form one complete system without need of welding, screwing, testing, surface treatment or without having problem of loosening.
Internal linings:
- Cement Mortar Lining - is a dense homogeneous layer covering the entire inner surface of the trunk of the pipe. The mixture of cement mortar contains cement, sand and water. Cement can be of several types depending on the type and chemical composition of the fluid pumped in the pipeline: ordinary portland cement (OPC), sulphate resistant cement (SRC), blast furnace slag cement (BFSC), high alumina cement (HAC). At the same time, the water used in the cement-sand mixture corresponds to the standard set for drinking water. The thickness of the cement-sand coating is for pipes DN40-300 - 4,00 mm, DN350-600 - 5,00 mm, DN700-1200 - 6,00 mm, DN1400-2000 - 9,00 mm, DN2200 - 12,00 mm.;
- Epoxy Seal Coat;
- Bituminous Seal Coat.
Outside coatings:
- Zinc Coating (130 gm/m²² or 400 gm/m²);
- Alloy of Zinc and Aluminum with a minimum mass of 400 gm/m².
Finishing protection layer:
- Blue epoxy (from 70 to 100 micron);
- Redepoxy;
- Black bitumen
Special coating:
- External and Internal Polyurethane Coating (DN 100 - DN 1600)
International standards: ISO2531, ISO7186, BS EN545, BS EN598, ISO:9001, ISO:14001.
Competitive advantages:
- Quick and safe installation thanks to the locking system;
- Fast execution of the installation and possibility of reducing the number of fittings, even in the case of land with irregular elevation course, due to the high angular deviation;
- Excellent behavior in case of earthquake;
- Low roughness that determines minimum pressure losses Resistance to corrosion by corrosive waters;
- Resistance to corrosion by aggressive soils in most of the cases.
IMPORTANT! The technical specialists of our company are always ready to help you make the right choice of Ductile Iron Pipes taking into account the characteristics of the pumped medium, the working pressure in the system, the specifics of the soil for laying pipes and a number of other important factors that will ensure the durability of the pipeline system built using high quality JINDAL pipes.
