At Keiyo Kogyo Co., Ltd., we carry out a large number of special orders for fittings, prototype production of special fittings, and special processing. With our proven processing technology for PVC pipes and fittings, we can manufacture pipes and fittings with special shapes. In addition to PVC pipes, we also perform blow molding and special processing of various plastics (such as PP, PE, PVDF, PPS, etc.). If you are considering obtaining special-shaped or small-lot fittings, or prototypes, please feel free to contact us. As an example of special processing at Keiyo Kogyo Co., Ltd., we would like to introduce the "PVDF Pipe Bend." 【Example of Special Processing: "PVDF Pipe Bend"】 - As a fitting for artificial dialysis piping, we previously used molded elbows, but there was a challenge that the accumulation of impurities due to air pockets compromised safety and reliability. - As a solution, we accepted the order for the production of large-radius bends. - The secondary processing of PVDF pipes has a high heat resistance, and the temperature range for molding processing is very narrow at ±5°C, making it difficult to process bends within that range. - We have already had over two years of delivery records with no complaints.

Branch extraction fusion processing refers to the technology of fusing multiple branch pipes to PE pipes. We have developed a dedicated automatic fusion machine by understanding the optimal fusion conditions. Conventional stainless steel options are high in both reliability and cost, and using molded products comes with design limitations. With our "PE header pipe branch fusion technology," we can provide fused branch pipes with high reliability and low cost. ★ This is a fused branch pipe made from the difficult-to-process PE100. After conducting pressure tests, it showed no water leakage at a pressure of 2.5 MPa for 2 minutes! This low-cost fused branch pipe was made possible by the development of a dedicated automatic fusion machine through understanding optimal fusion conditions. 【Features】 ■ Lower cost compared to continuous tee pipes ■ Can accommodate a large number of branches ■ Branch pipe connections can be either EF connections or mechanical ■ PE pipes are lightweight, allowing for wall installation ■ Provides uniform pressure compared to branch pipe construction methods 【Recommended for!】 ◎ Those looking for compact unit piping ◎ Those wanting to introduce branch pipes at low cost ◎ Those struggling with corrosion in steel pipes ◎ Those considering switching to plastic pipes with excellent seismic resistance ◎ Those wanting to expand design flexibility ● For evaluation examples and application examples, please download the catalog.
