Purchasing Guide

Based on real user feedback, we provide the following suggestions:

  • For procurement requirements that require the use of straight seam welded steel pipes, it is recommended to prioritize confirming key technical parameters such as outer diameter, wall thickness, and material grade, such as API 5L standard pipeline steel or ASTM A53 structural pipes, to ensure compatibility with fluid transport or pressure bearing scenarios.
  • In different application scenarios such as oil and gas transportation or building support, the anti-corrosion coating type (such as FBE or 3PE) and weld detection level of straight seam welded steel pipes need to be selected differently according to the corrosion environment or load requirements.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. For example, manufacturers who have been involved in large-scale infrastructure projects for a long time usually have more stable production capacity guarantees.
  • When using straight seam welded steel pipes in municipal water supply and drainage projects, attention should be paid to whether the supplier provides galvanized or black pipes that comply with GB/T 3091 standards, and the supplier's industry data support capabilities should be used to evaluate their product consistency.
