Saudi Arabian Ductile Iron Pipes Co. Ltd. (SADIP) A pioneer in the Middle East, Ductile emerged in January 1988 as a visionary joint venture  A pioneer in the Middle East, emerged in January 1988 as a visionary joint venture between the esteemed Saudi Arabian AMIANTIT Co., the region’s leading pipe manufacturer, and the formidable Pont-a-Mousson. Renowned for its unparalleled expertise and over 130 years of experience in ductile iron pipes and fittings, Pont-a-Mousson not only supplied the technology and equipment but also partnered in knowledge and process development. This collaboration ensured SADIP’s rapid growth and success. Saudi Arabian Ductile Iron Pipes Co. Ltd. (SADIP) proudly holds the distinction of being the first plant in the Middle East to utilize the centrifugal production process for ductile iron pipes. Their steadfast commitment to quality is reflected in their adherence to rigorous standards like ISO 2531, BS EN 545, and SASO 1020. This dedication culminated in the prestigious King’s Award, a testament to Saudi Arabian Ductile Iron Pipes Co. Ltd. (SADIP) unwavering pursuit of excellence in both processes and products.

Pipe Joints

• Standard Push-on joint:

The standard joints for the pipes are designed so that contact pressure between the gasket and the metal increases as the water pressure increases, thus a perfect seal is guaranteed.

• Advantages:
  • Easiness of assembly
  • Allowable Joint Deflection

SADIP socket – spigot joints permit angular deflection which gives the following advantages:

• Accommodation of ground movements as shown in the diagrams below.
• Allowing adjustment while installation.
• Reducing the number of bends required.
• Locked Standard Push-On Pipes:

The Locked Push-On pipes are like the standard type, except that pipe is supplied with weld bead at the near end of the spigot (distance “a” in below drawing). The purpose of the weld bead is to make the pipe suitable to accommodate restrained joint. Restrained joints are required on above ground. Locked pipe can be supplied with full-restrained joint accessories (glands, rings, bolts, and nuts).

joints:

Flanged pipes and fittings can be supplied with various flange specifications like PN10, PN16, PN25, PN40, BS10 & ANSI as agreed with Plant.

Flanged pipes can be supplied with deferent length as agreed between Customer/s & Plant including puddles.

Flanged fittings will be supplied based on the dimensions available in SADIP catalogue.

• Mechanical & Express Joints:

Collars supplied with mechanical or express joint depending on the customer requirements and in line with the dimensions and details given in SADIP catalogue.
