京葉興業 Product Lineup

At Keiyo Kogyo Co., Ltd., we carry out a variety of special orders for fittings, prototype production of special fittings, and special processing. Our proven processing technology for PVC pipes and fittings enables the production of specially shaped pipes and fittings. Additionally, we also perform blow molding and special processing of various plastics, not just vinyl chloride pipes (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 "blow-molded PVC pipe products." 【Example of Special Processing: "Blow-Molded PVC Pipe Products"】 ○ We received a request for molded products to create a slope within a limited space for fittings used in underfloor piping. → Due to the inability to fit conventional injection-molded fittings like elbows in that space, we proposed a prototype of a bending fitting with a pipe diameter R. ○ We accepted a request for prototype processing of compact-sized drainage fittings. → The R is approximately 40R for a bending section with a pipe diameter of 60, and it was delivered as a prototype since other companies were unable to produce it.

At Keiyo Kogyo Co., Ltd., we carry out numerous 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 fittings with special shapes or small lots, or if you need prototypes, please feel free to contact us. As an example of special processing at Keiyo Kogyo Co., Ltd., we would like to introduce the "S-shaped blow fitting." 【Example of Special Processing: "S-shaped Blow Fitting"】 - A blow-molded product made from thin-walled olefin pipes with a small diameter, requiring strict management of molding conditions, including temperature control. - Please consult us for shapes that cannot be achieved through injection molding, direct blow molding, or parison blow molding. For more details, please contact us or download our catalog.

The "dissimilar diameter socket" is a hard PVC fitting used to connect pipes of different types in civil engineering and electrical underground construction (dissimilar pipe fittings). It is used to connect pipes of different types and diameters that are buried in civil engineering and electrical work. Please feel free to contact us when you need assistance. 【Features】 ■ A socket for connecting dissimilar pipes such as fume pipes and PVC pipes, communication bellows and PVC pipes, ceramic pipes and PVC pipes. ■ It accommodates connections between pipes of different diameters with receiving mouth processing, such as 100×150mm, 100×200mm, 125×200mm, etc. *For more details, please feel free to contact us.
