Welcome To National Pipe Co. Ltd.
The establishment of the company was envisioned by Sumitomo Group of Japan together with Saudi investors to provide local supply of quality pipes for the oil, gas, water and construction services at the time of rapid industrialization in the kingdom. This started the birth of National Pipe Company, Ltd. located in Dhahran area just 15 kilometers away from one of its major customers.
The first plant with a capacity of 180,000 Metric Tons per year started its commercial production in August 1980. It was designed to produce helical seam SAW large diameter pipes with outside diameters ranging from 20”-60” (508-1524mm) with pipe wall thickness of 0.250” - 0.875” (6.4 - 22.2 mm) and grades ranging from API 5L Grade B - X70. In 2007 the plant was upgraded to produce pipes with larger diameters up to 84”(2134mm) for a rated capacity of 250,000 Metric Tons per year.
To meet the market demand for high pressure gas line pipes, NPC started to produce Longitudinal seam SAW pipe by constructing the second pipe plant with rated production capacity of 180,000 Metric Tons. The plant started its commercial production in 2001producing longitudinal pipes with outside diameters ranging from 24”-60” (610-1524 mm) and 0.250” -1.200” (6.4 - 30.5 mm) wall thickness with grades ranging from API 5L Grade B - X70.
Since the start of its production thirty years ago up to the fiscal year of 2010, NPC’s helical seam SAW pipe mill production reached 3, 300, 000 MT while longitudinal seam SAW pipe mill production reached 654, 000 MT.
