Technical Specifications

Materials for Different Oil Transportation Conditions

Material selection is an important part of oil pipeline design. Shunchen provides spiral welded steel pipes in different material options to accommodate different transportation and environmental requirements.

Corrosion Protection for Oil Transportation Pipelines

Corrosion protection can play an important role in extending the service life of steel pipeline systems. Shunchen provides several surface treatment options, including galvanizing, spraying, and anti-corrosion coatings.

The appropriate surface treatment depends on factors such as pipeline location, soil or atmospheric exposure, transported medium, temperature, installation method, and project specifications. For oil transportation applications, coating requirements can be discussed during the specification stage so that the pipe and surface protection system are matched to the intended service environment.

Manufacturing and Quality Control

Shunchen manages steel processing and surface treatment capabilities as part of its integrated industrial operations. The company has developed from a steel trading business into a group integrating steel processing, galvanizing, anti-corrosion treatment, logistics, and international trade.

Quality control is applied throughout the manufacturing and processing stages. Depending on the product specification and project requirements, inspection can include dimensional checks, mechanical property verification, ultrasonic flaw detection, hardness testing, and other applicable quality inspections.

For oil transportation projects, inspection requirements should be confirmed according to the applicable product standard, project specification, material grade, and customer requirements.

Applications 

Spiral Welded Pipe for Oil Transportation can be used in different sections of oil transportation infrastructure where large-diameter steel pipelines are required. Typical applications include:

• Long-distance oil transportation pipelines
• Large-diameter crude oil pipeline systems
• Onshore oil pipeline infrastructure
• Industrial fluid transportation systems
• Pipeline sections requiring customized diameter and wall thickness

The final pipe specification should be determined according to the pipeline design, operating conditions, applicable standards, and installation environment rather than selecting the pipe based on diameter alone.

Customization for Oil Pipeline Projects

Different oil transportation projects may require different pipe diameters, wall thicknesses, steel grades, lengths, and surface protection systems. Shunchen supports customization of these specifications according to project requirements.

Available customization options include material selection, outside diameter, wall thickness, pipe length, surface treatment, cutting, and beveling. The technical team can review the intended application and help determine a suitable pipe specification based on the customer's technical requirements.
