This anticorrosive spiral steel pipe is manufactured using the helical submerged arc welding process, with base materials including carbon steel grades Q235, Q345, Grade B, and API 5L X42 to X80. The pipe is protected with advanced coating systems such as 3PE, FBE, or two-cloth three-oil coal tar epoxy, ensuring long-term resistance to corrosion in harsh environments like oil and gas transmission, water supply networks, and sewage systems.
The two-cloth three-oil coating system, also known as three-oil two-cloth anticorrosive treatment, applies three layers of epoxy coal tar paint with two layers of glass cloth reinforcement. This method is widely recognized for its durability and is a standard for buried or submerged pipelines. Typical pipe diameters range from 219 mm to 3000 mm, with wall thicknesses varying by grade and application requirements.
These pipes are a key commodity in global infrastructure projects, with demand from the Middle East, Southeast Asia, and African markets. They are subject to strict quality certifications, including API 5L, ISO 3183, and GB/T 9711, ensuring compliance with international standards for material properties, dimensions, and performance. Buyers should confirm specific certification status with the supplier.

Before ordering, verify the pipe’s material grade, coating system, and dimensions to ensure they match your project specifications. Request mill test certificates and coating inspection reports to confirm compliance with API, ISO, or GB/T standards. If your project requires third-party certification, such as from DNV or ABS, confirm the supplier’s ability to provide it.
Discuss logistics, including lead times for production and coating application, as these can vary significantly by order size. Clarify packaging options, such as bundled or loose loading, and confirm the Incoterms (e.g., FOB Qingdao or CIF destination port). Payment terms, such as irrevocable L/C or T/T with a down payment, should be negotiated to align with your procurement policies.
Upon delivery, inspect the pipes for dimensional accuracy, coating uniformity, and absence of defects. Conduct visual and non-destructive tests, such as holiday detection for coatings, to ensure quality. For long-term storage, protect the pipes from moisture and mechanical damage, and re-inspect coatings before installation to maintain anticorrosive performance.
