Seamless Steel Pipe for Oil and Gas and Industrial Pipeline Applications
Seamless steel pipes are essential components in modern industrial pipeline systems due to their excellent strength, pressure resistance and durability. Shaanxi Gold-Stone I/E Co., Ltd. supplies high-quality seamless steel pipes widely used in oil and gas transportation, construction engineering and industrial fluid systems.
Our seamless pipes are manufactured according to internationally recognized standards such as ASTM A106, ASTM A53 and API 5L to ensure stable mechanical performance and reliable quality. These standards are widely required in oil & gas pipelines, power plants, petrochemical facilities and structural engineering projects.
The seamless steel pipes supplied by Shaanxi Gold-Stone are available in a wide size range from 1/8 inch to 24 inches outer diameter (5.0 mm – 716 mm), with wall thickness from 0.3 mm to 26 mm. Various pipe schedules including SCH20, SCH40, STD, XS, SCH80, SCH160 and XXS are available to meet different pressure requirements and engineering specifications. Standard pipe length is up to 12 meters, and customized lengths can also be provided according to project requirements.
To improve durability and corrosion resistance, several surface treatment options are available, including black painting, galvanized coating, oil coating, and advanced anti-corrosion coatings such as PE, 3PE and FBE coatings. These protective layers significantly extend the service life of pipelines used in demanding environments such as offshore platforms, chemical plants and long-distance transmission pipelines.
