Spiral Pipe for Oil and Gas Pipeline is a key structural pipeline product specially designed for oil and gas gathering,transmission,long-distance transportation and distribution systems.Made by rolling hot-rolled steel coils into a continuous helical shape and welded with double-sided submerged arc welding,it features high pressure resistance,good rigidity,stable performance and strong adaptability to complex geological environments.It is widely used in onshore and offshore oil and gas pipelines,natural gas trunk lines,crude oil transmission pipelines and associated energy engineering.
Key Features
High Pressure Bearing Capacity:Meets API 5L standard specifications,suitable for medium and high pressure oil and gas transmission working conditions.
Excellent Structural Strength:Helical weld design effectively disperses stress,improves resistance to deformation,external pressure and soil load.
Wide Size Range:Supports large-diameter and thick-wall specifications,meeting the needs of large-flow long-distance pipelines.
Strong Corrosion Resistance:Can be equipped with external 3PE,FBE,internal anti-corrosion coating and other treatments to adapt to buried,humid and corrosive media environments.
High Welding Quality:Adopts automatic welding and full-process non-destructive testing(UT,RT,hydrostatic test)to ensure sealing and safety.
Good Construction Adaptability:Stable performance in low temperature,earthquake and complex terrain areas,with reliable connection performance.
