Purchasing Guide

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

  • For procurement requirements that require the use of straight seam submerged arc welded steel pipes, it is recommended to prioritize the confirmation of key parameters such as pipe diameter, wall thickness, and steel grade to ensure that they match the pressure of the conveying medium or the structural load-bearing requirements, especially when applied in oil and gas pipelines or building support fields, strict accounting is required.
  • When selecting suppliers, reference can be made to product compatibility, business qualifications, enterprise activity, industry performance, and platform statistical information. For example, enterprises that have been involved in large-scale infrastructure projects for a long time usually have more stable process control capabilities.
  • In the anti-corrosion scenario of offshore platforms, attention should be paid to the crack resistance and coating performance of straight seam submerged arc welded steel pipes. When purchasing, suppliers can be required to provide third-party inspection reports to verify key indicators.
  • There are different requirements for the straightness and ellipticity of steel pipes in different application scenarios. Urban water supply and drainage engineering usually has a higher tolerance than high-pressure gas pipelines. It is recommended to flexibly adjust the acceptance standards according to actual working conditions.
