The Company took over the existing Sui-Multan System with 217 miles (349 km) of 16 inches (410 mm) and 80 miles (130 km) of 10 inches (250 mm) diameter pipelines from Pakistan Industrial Development Corporation (PIDC) and Dhulian-Rawalpindi-Wah system with 82 miles (132 km) of 6 inches (150 mm) diameter pipeline from Attock Oil Company.
During the IPS period, pipes were cast in halves and welded together, and pipe sizes referred to the inside diameters. [1] The inside diameters under IPS were roughly the same as the more modern Ductile Iron Pipe Standard (DIPS) and Nominal Pipe Size (NPS) Standards, and some of the wall thicknesses were also retained with a different ...
The pipeline will be 1,420 mm (56 in) in diameter with a working pressure of 100 atm (10,000 kPa). [23] The capacity will be 33 × 10 ^ 9 m 3 (1.2 × 10 ^ 12 cu ft) of natural gas per year of which 5 × 10 ^ 9 m 3 (180 × 10 ^ 9 cu ft) will be provided to Afghanistan and 14 × 10 ^ 9 m 3 (490 × 10 ^ 9 cu ft) to each Pakistan and India.

However, as a bilateral project between Iran and Pakistan, the pipeline will carry only 8.7 billion cubic metres (310 billion cubic feet) of gas per year as contracted and 40 billion cubic metres (1.4 trillion cubic feet) as a maximum capacity. The pipeline has a diameter of 56 inches (1,400 mm). [52]
Oil pipelines are made from steel or plastic tubes with inner diameter typically from 4 to 48 inches (100 to 1,220 mm). Most pipelines are typically buried at a depth of about 3 to 6 feet (0.91 to 1.83 m). To protect pipes from impact, abrasion, and corrosion, a variety of methods are used.
Nominal Pipe Size (NPS) is a North American set of standard sizes for pipes used for high or low pressures and temperatures. [1] " Nominal" refers to pipe in non-specific terms and identifies the diameter of the hole with a non-dimensional number (for example – 2-inch nominal steel pipe" consists of many varieties of steel pipe with the only criterion being a 2.375-inch (60.3 mm) outside ...
Consequently, a 1-inch (25 mm) copper pipe had a 1 + 1 ⁄ 8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings. The wall thickness on modern copper is usually thinner than 1 ⁄ 16-inch (1.6 mm), so the internal diameter is only "nominal" rather than a controlling dimension. [13]
The energy consumed in manufacturing ductile iron pipe was 19.55 MJ per kg and volume of emissions released during manufacture was 1.430 kg CO 2 per kg, compared to 68.30 MJ per kg of energy and 4.860 kg CO 2 per kg emissions for PVC pipes, and 1.24 MJ per kg and 0.148 kg CO 2 per kg for concrete pipes of the same diameter.
