These line pipes, often used to transfer liquid and air, meet the following standards: AWWA C200, ASTM 139, ASTM 134, and ASTM 135. Steel pipe has many advantages to offer, including strength and weight, ease of installation, and cost. Wldsteel is SPFA certified and produces 18” OD to 90” OD hydrotested line pipe using a double submerged arc weld process for a variety of applications, including but not limited to, water transmission pipelines, slurry pipelines, gravity sewer mains, sewer force mains, intake and […]
