Raw Materials

Selection of Galvanized Steel

Galvanized steel is the primary raw material used in GI pipe manufacturing. It is chosen for its durability, corrosion resistance, and strength. Cangzhou Shenlong meticulously selects high-quality galvanized steel for its pipes and fittings to ensure longevity and reliability in diverse applications. The selection process involves rigorous assessments of the steel's chemical composition, mechanical properties, and coating thickness to meet industry standards and customer requirements.

Quality Control Measures

Cangzhou Shenlong implements stringent quality control measures throughout the raw material procurement process. This includes thorough inspections of incoming galvanized steel to verify its conformity to specified standards. Quality control personnel conduct visual inspections, dimensional checks, and material testing to identify any defects or deviations. Any non-conforming materials are rejected, ensuring that only superior-quality galvanized steel is utilized in manufacturing. By maintaining rigorous quality control protocols, Cangzhou Shenlong upholds its commitment to delivering premium GI pipes and fittings that meet the highest performance and reliability standards.

Manufacturing Process

Cutting and Shaping

The manufacturing process begins with the cutting and shaping of the selected galvanized steel. Advanced machinery and cutting-edge technologies cut steel sheets or coils into the desired dimensions for forming pipes and fittings. Computer-controlled equipment ensures accuracy and consistency in cutting, optimizing material utilization, and minimizing waste.

Welding and Joining

Once the steel components are cut to size, they undergo welding and joining processes to form the desired pipe and fitting configurations. Skilled welders use specialized welding techniques, such as arc welding or gas metal arc welding (GMAW), to fuse the steel components seamlessly. Proper welding parameters and procedures are strictly followed to ensure strong and durable joints that withstand the rigors of use in demanding applications.

Galvanization Process

After fabrication, the GI pipes and fittings undergo the galvanization process to apply a protective zinc coating to the surface of the steel. This coating provides enhanced corrosion resistance, extending the lifespan of the pipes and fittings in harsh environments. Cangzhou Shenlong employs state-of-the-art galvanizing techniques like hot-dip galvanizing to ensure uniform coating thickness and adherence to stringent quality standards.

Quality Checks at Each Stage

Throughout the manufacturing process, Cangzhou Shenlong conducts comprehensive quality checks at each stage to maintain product integrity and performance. Experienced inspectors monitor the production process, performing visual inspections, dimensional measurements, and material testing to verify compliance with specifications. Quality checks are conducted before, during, and after fabrication, ensuring that only flawless GI pipes and fittings are released to customers. By prioritizing quality assurance at every step, Cangzhou Shenlong ensures its products' reliability and durability, earning customers' trust and confidence worldwide.
