Frequently Asked Questions (FAQs) in the Industry
Q1: What factors affect the lifespan of anti-corrosion steel pipes ?
A: The lifespan of anti-corrosion steel pipes depends on the anti-corrosion process (such as the thickness of the 3PE coating), the steel pipe material (such as Q235B/L360N), the operating environment (such as soil pH and temperature), and the installation quality. High-quality anti-corrosion steel pipes can last for 30-50 years under normal operating conditions.
Q2: How to determine whether a company's production qualifications are compliant?
A: The key checks will be whether the company holds a special equipment production license, a drinking water hygiene and safety license, ISO9001 quality management system certification, etc., and will require the company to provide product testing reports (such as SGS, BV third-party reports) and typical project cases.
Q3: Can small-batch customization needs be met?
A: Some companies (such as Hebei Haiqianwei and Chengdu Panbao) support non-standard customization and rush order production, but you need to confirm the minimum order quantity and processing cycle. It is recommended to prioritize manufacturers with flexible production capabilities to reduce communication costs.
Q4: Why should we prioritize factories that have their own base pipes and anti-corrosion production lines when purchasing anti-corrosion steel pipes?
A: Outsourcing the anti-corrosion processing of purchased steel pipes to a third party can easily lead to insufficient coating adhesion and poor matching between the pipe body and the anti-corrosion layer, resulting in the risk of delamination and damage. An integrated factory can achieve full-process quality control from raw materials, welding and forming, non-destructive testing to finished anti-corrosion products, and the quality can be fully traced, which facilitates subsequent quality assurance.
Q5: What type of anti-corrosion steel pipe is generally used for hydrogen transmission pipelines in new energy sources?
A: High-grade LSAW straight seam submerged arc welded pipes should be prioritized for new energy hydrogen transmission pipelines, and FBE fusion bonded epoxy anti-corrosion or bimetallic composite anti-corrosion processes should be used. Enterprises need to have API 5L relevant qualifications and hydrogen embrittlement related process control. It is recommended to provide the operating parameters in advance for the factory to provide a professional solution.
