To this end, first the flanged part is welded to the flange; then, one side of the fitting is screwed to the end of the metal pipe and the other side is screwed to the polyethylene pipe, and the connection is made in this manner. This way, the connection is reinforced while the pipeline sees no damage. Yasmin group provides and supplies high-quality flanged fittings and related accessories to enable simple purchasing for customers.

All equipment and parts used for flanged fittings are produced using lost foam casting methodology which is one of the most recent casting methods available.

Furthermore, L.Pipe fittings can replace the aforementioned pipes in different conditions and according to the requirements in various industries. Similar to other piping and fitting equipment, L.Pipe fittings are manufactured according to the international standard ISO 16631 and the national standard INSO 21376.

Nominal thickness for these pipes and fittings vary between 3 and 4 millimeters. In general, thin walled fittings include tee fittings, wyes, elbow fittings, crosses, kevlars, socket weld flanges, adapters, and spigot flanges.

 The thin-walled LPs are a new generation of ductile iron pipes with less wall thickness than those of Titan’s ductile pipes. Therefore, their use in drinking water distribution system is the much more logical, engi-neered and economical due to the dramatic reduction in weight.

 Since the ductile iron pipes is the preferred option for drinking water lines, the LPs has been the best re-placement for polymeric pipes in drinking water distribution lines, along with all the advantages of its duc-tile iron such that it has eliminated many deficiencies and limitations in the polymer pipes, such as restric-tions on outdoor maintenance and storage, environmental issues, higher maintenance due to the fracture and leakage of polymeric pipes, and so on.

Standards 

The LPs is manufactured and supplied according to the Yasmin group factory standard, complying with the international standard ISO 16631-2016 and the national standard INSO 21376 with 3-4 mm nominal thickness. Other product specifications, such as external coating, interior lining, etc., are in accordance with ISO 8179 and ISO 4179 international standards and EN 545: 2010.

Applications Ductile Iron Light Weight Pipe – L.Pipe  :

• A suitable replacement for polymer pipes in the drinking water distribution system;
• The best option in low-pressure distribution lines;
• Easy to carry in hard to reach areas by hand where it’s difficult to carry normal weight pipes;

 ipes are mainly employed in pipelines for an increase in stability and resistance to implementing such p  forces on pipeline structure. Puddles work as a preventive agent against hydraulic forces and help protect pipelines from forces caused by sudden changes in fluid pressure. To fulfill this goal, pipes with puddles are laid at the point where the pipeline is connected to the input of the water supply main such as boiling room or pumping stations. In these cases, the pipes with puddle is planted inside the walls of a container attached to the valve there. Moreover, use of these pipes in cement blocks could result in more stability and strength in the pipeline over sloped areas.

Types of pipes with puddle

• Double flanged ductile iron pipe with puddle
• Double spigot ductile iron pipe with puddle
• Flanged spigot ductile iron pipe with puddle

 R.J.Pipe is a Push-on restrained joint of advanced design.The joint locking system prevent joint separation. The R.J.Pipe joint is used primarily to earthquake and subsidence resistance ductile iron pipelines.lt may also be used for trenchless application systems.

The design provides joint deflection after assembly and easy installation without bolts and nuts. This kind of pipes produced according to ISO 2531 and the joint tested according to ISO 10804

Advantage Ductile Iron Pipe R.J.PIPE 

 Easy and fast installation

 Can withstand high pressure compared with Tyton joints

Capable of linear and angular deflection

 Boltless push-on restrained joint

Application Ductile Iron Pipe R.J.PIPE 

 Restrained fittings can be used instead of concrete trust blocks

 Suitable for earthquake zone and unstable soils

Suitable for bridge crossing, horizontal directional drilling, highway and railroad crossing

Q.R. Pipe is a push-on joint of restrained joints family. It has angular and axial deflection movement against thrust forces and it is constrained and resistant against thrust forces. ISO 16134 considers it as a Quake Resistant joint. In these types of pipes, joint-locking parts are fitted into a chamber in a way that there is no need for bolts and nuts or welding. The assembly of pipes using a pushing method seals them completely and secures the joint section of two pipes.

 One of the unique specifications of a Q.R. Pipe is its angular and axial deflection movement. Under seismic conditions, axial thrust force is distributed on one or many pipes and the pipeline’s overall behavior will be as a chain structure.

Application Ductile Iron Q.R. Flex Pipe

• In high-steep and hilly regions
• Suitable for all types of soils, lands, especially regions with loose, unstable, and marshy soil.
• On faults and earthquake-prone regions.
• Regions where installation of inhibitory concrete blocks is impossible.

Advantage Ductile Iron Q.R. Flex Pipe

• Easy and quick assembly operation without any glands, nuts and bolts, and other components.
• Improving pipeline resistance against thrust forces and joint protrusion and creating a chain structure on pipelines.
• The best choice for Pipe-jacking, and Trenchless laying and Horizontal Direction Drilling (HOD).
• Suitable for earthquake-prone regions and loose and unstable soils.
• Reducing execution costs with respect to needing no shock-absorbing and cement thrust blocks.
• Considerable reducing of waste of water in transferring pipeline and distribution networks.

Advantages Tyton Joint Ductile Iron Pipe

• Easy and fast installation, without special equipment and expert manpower
• Proper angular deflection
• Not require welding and using bolt and nut
• Perfect sealing

Yasmin group manufactures different types of ductile iron with various sizes between 80 to 800 millimeters in order to achieve high quality when providing and installing sewage fittings and related accessories. Moreover, in order to enhance sewage connectors with different operating pressures, this company provides these fittings with different kinds of inner cement cover.

With this feature included, sewage fittings do not experience damage, wear, and corrosion even in high operational pressures. These fittings are manufactured with the highest possible quality according to international standards ISO 2521, EN545, and ISO 7185. Also worth a mention is that the cement cover used inside sewage fittings is made of high alumina cement, which is merely used for sewage purposes.

In general, a specific washer must be used in each fitting. In flanged fittings, usually plastic washers are used in order to increase resistance and strength between the two flanges. Similar to other water transfer fittings and equipment, tyton fittings are produced according to the ISO2531 and EN545 standards.
