Project Case: Weld Neck Flange & Pipe Cap | Serbia
Project details
Order Details
In the summer of 2025, we established a partnership with a client in Serbia. At that time, the customer was urgently seeking a batch of high-quality flanges for an industrial project. Among numerous suppliers, our reputation for technical expertise and consistent product reliability distinguished us as their preferred choice.
From the initial discussions, the client emphasized their stringent requirements for flange quality and precision, as these factors were critical to the safety and stability of their project. Our sales team responded promptly, presenting in detail our production processes, quality control procedures, and the reliable sources of our raw materials.
Despite this, the client still expressed concerns regarding dimensional accuracy and material strength. To address these issues, our engineers engaged in multiple rounds of in-depth communication, providing technical explanations and sharing proven case studies. This professional support reassured the client and ultimately led to the successful signing of the order.
Once the order was confirmed, production began without delay. Each stage of the process was executed with meticulous attention to detail. Premium-grade steel was selected, and advanced CNC machining equipment was used to ensure precise manufacturing. During machining, precision measurement tools such as vernier calipers were employed to continuously check and adjust key dimensions—including inner and outer diameters, thickness, and bolt-hole sizes—ensuring complete accuracy.

Equal care was applied to surface treatment. After processing, the flanges exhibited a smooth, mirror-like finish with a uniform metallic texture. This not only enhanced their appearance but also significantly improved resistance to corrosion and wear.
Upon completion, the products were packaged according to the client’s specifications. Reinforced wooden crates were used, with comprehensive protective measures inside each package to guarantee the flanges remained undamaged during long-distance transport.
