How to judge the quality of spiral steel pipes?
Spiral steel pipes are widely used in pipelines for water, oil, gas, and structural applications. However, not all products on the market meet the same quality standards. Poor-quality pipes can lead to leakage, deformation, or even safety hazards during service. Therefore, understanding how to evaluate the quality of spiral steel pipes is essential for engineers, purchasers, and contractors. Below are several practical methods to help you distinguish between high-quality and substandard spiral steel pipes.

Material re-inspection of SMLS pipe
Material re-inspection of SMLS (Seamless) pipes is a crucial quality verification process conducted when steel pipes arrive at the user’s site, during production, or before storage. The purpose is to confirm that the pipe’s chemical composition and mechanical properties meet the requirements of the purchase contract and relevant standards. Re-inspection is typically carried out when there are concerns about the product’s quality, doubts regarding the manufacturer’s warranty, or when project specifications require mandatory re-testing. The following provides a comprehensive overview of the purpose, items, and procedures involved in the re-inspection of seamless steel pipe materials.
