Purchasing Guide

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

  • For procurement requirements that require the use of straight seam pipelines, it is recommended to prioritize confirming key technical parameters such as pipe diameter, wall thickness, and material to ensure compatibility with the conveying medium and pressure rating. For example, oil and gas transportation scenarios typically require higher compressive performance.
  • When selecting suppliers, priority should be given to product compatibility, business qualifications, enterprise activity, industry performance, and companies with industry data support. These suppliers usually perform more stably in the supply of straight seam pipelines in chemical or municipal water supply and drainage fields.
  • In applications in high temperature or corrosive environments, it is recommended to pay attention to the type and temperature resistance range of anti-corrosion coatings for straight seam pipelines, such as pipelines that require special alloys or plastic lining processes for power plant desulfurization systems.
  • Different scenarios have differentiated requirements for the length and connection method of straight seam pipelines. For example, long-distance water transmission projects need to consider segmented welding processes, while the factory pipeline network may pay more attention to the convenience of flange connections.
