Production process where flange and base pipe are welded together

At Haihao Group, we thrive on challenging projects that push the boundaries of innovation and excellence. Recently, we embarked on an exciting journey with a customer who had unique requirements for their base pipe and flange combination. In this article, we will delve into the technical discussions, production plan, encountered difficulties, and our relentless determination to overcome them.

Technical Discussions: Collaboration for Success

From the onset, our technical team engaged in extensive discussions with the customer to fully understand their specific needs and project goals. We analyzed the requirements for the base pipe, including DN150 size, ASTM A53 specifications, and SCH40 thickness. Simultaneously, we delved into the intricacies of the flange, focusing on the PN25 size, plastic coating, and cable groove opening.

With a wealth of industry expertise and a commitment to customer satisfaction, our technical team explored various production approaches, considering factors such as material compatibility, manufacturing feasibility, and compliance with international standards. Through open communication and collaborative problem-solving, we were able to devise a production plan that met the customer’s expectations while ensuring the highest quality and performance.

Production Plan: Precision and Expertise

Based on our technical discussions, we formulated a comprehensive production plan that incorporated the customer’s specific requirements. The base pipe, manufactured with DN150 sizing and ASTM A53 specifications, underwent a meticulous production process. Our skilled craftsmen carefully controlled the SCH40 thickness, ensuring precise dimensions and impeccable structural integrity. Additionally, the galvanization process posed a significant challenge due to the requirement for a thickness of 560g. However, our experienced technicians employed advanced techniques to achieve the desired coating thickness, safeguarding the base pipe against corrosion and extending its lifespan.

For the flange, our production plan encompassed a meticulous welding process to seamlessly connect it to the base pipe. Subsequently, we embarked on the innovative plastic coating step, which involved precisely applying a protective layer onto the flange’s surface. To meet the customer’s specific request, we skillfully opened a cable groove on the flange, allowing for efficient cable management during installation. This design element showcased our commitment to practicality, ensuring ease of use and enhanced project efficiency.

Overcoming Challenges: Striving for Perfection

Throughout the production process, we encountered several challenges that tested our capabilities and determination. One significant difficulty was achieving a uniform galvanized coating thickness of 560g on the base pipe. To overcome this, we meticulously controlled the galvanization parameters, such as temperature, immersion duration, and zinc material quality. Our unwavering attention to detail and adherence to strict quality control measures ensured that each base pipe met the specified galvanized thickness, guaranteeing optimal performance and longevity.

Another challenge arose during the plastic coating process for the flange. Achieving a smooth and uniform coating required precision application techniques. Our skilled craftsmen employed their expertise to ensure consistent coverage, thickness, and adhesion. Through rigorous testing and meticulous inspection, we verified that each plastic-coated flange met our high standards of quality and durability.
