Special Equipment Manufacturing License

The Special Equipment Manufacturing License obtained by Cangzhou Spiral Steel Pipe Manufacturing Group Co., Ltd. is a mandatory administrative license issued by the State Administration for Market Regulation of China or its authorized agencies. This certificate serves as a qualification for manufacturing special equipment such as pressure pipeline components (e.g., spiral steel pipes), boilers, and pressure vessels, and certifies that the enterprise possesses the capability to manufacture special equipment in compliance with safety technical specifications and ensure safe production.

This certification signifies that our Group complies with national regulations and safety standards in the following key areas:

1. Legal Production Qualifications:

This license is a legal prerequisite for engaging in the manufacture of special equipment (such as pipelines used to transport flammable, explosive, toxic, or corrosive media, or those subjected to certain pressures) within China. Unlicensed production constitutes a violation of the law. Obtaining this certificate indicates that our Group’s production facilities, process equipment, testing methods, personnel qualifications, and quality assurance system have passed rigorous scrutiny by government regulatory authorities and meet the requirements of the “Special Equipment Safety Law” and relevant technical specifications (such as TSG 07-2019 “Rules for the Licensing of Special Equipment Production and Filling Units”).

2. Systematic Assurance of Safety and Quality:

The certification process requires enterprises to establish and operate a quality assurance system covering the entire production process, including design, materials, processes, welding, inspection, and testing. Particularly for pressure-bearing equipment such as spiral welded steel pipes, the certification process focuses on reviewing critical aspects such as welding procedure qualification, welder qualifications, non-destructive testing capabilities, physical and chemical testing, and hydrostatic testing. This ensures that every steel pipe leaving the factory is traceable and meets the safety requirements for operation under its intended service conditions.

3. Definition of Market Application Scope:

The license clearly specifies the permitted product types, grades, and parameter ranges (e.g., submerged arc welded spiral steel pipes, nominal diameter range, material grades, permitted pressure ratings, etc.). This provides customers with clear product application boundaries, ensuring that the products supplied by our Group strictly fall within our approved and verified manufacturing capabilities. It serves as a crucial basis for equipment selection, safety assessments, and compliant procurement in engineering projects.

Our Group will strictly comply with all regulations of the Special Equipment Manufacturing License, consistently prioritizing product safety and quality, and providing legal, safe, and reliable spiral welded steel pipe products for pipeline construction projects in the petroleum, natural gas, and chemical industries.
