Ismail Flanges, located in Jakarta, Indonesia, has built a solid reputation as a reliable manufacturer and supplier of EN 1092-1 Type 13 flanges. They specialize in precision-engineered solutions tailored for European-standard piping systems. EN 1092-1 Type 13 refers to loose plate flanges featuring a weld-on plate collar, which are particularly useful in situations that require frequent disassembly, flexibility in alignment, or protection against corrosion. These flanges are perfect for non-critical, low- to medium-pressure systems, especially in sectors like chemical processing, water treatment, HVAC, and food production. Ismail Flanges offers a diverse selection of Type 13 flanges in various pressure ratings (PN6 to PN40), materials, and sizes to cater to a wide range of industrial requirements.
EN 1092-1 Type 13 flanges are generally crafted from carbon steel (like P245GH, S235JR), stainless steel (such as 304, 316L), or duplex and alloy steels, depending on the specific application and medium involved. The weld-on collar and loose plate are designed to maintain dimensional accuracy and mechanical strength. The tensile strength typically falls between 360–600 MPa, while the yield strength ranges from 235–450 MPa, depending on the material used. This design allows the loose flange to move over the collar, making alignment easier and reducing stress in pipeline connections under moderate mechanical loads.
Ismail Flanges, a leading supplier in Indonesia, Jakarta, offers an extensive selection of EN 1092-1 Type 13 Flanges, including weld neck flanges, slip-on flanges, blind flanges, threaded flanges, and lap joint flanges. Designed for diverse industrial applications, our high-quality inventory and commitment to exceptional service make us a trusted choice for flange products in the region.

EN 1092-1 Type 13 flanges find their place in low- and medium-pressure pipelines where corrosion resistance, flexibility, or regular maintenance is essential. They are widely used across industries such as chemical processing, food and beverage, water distribution, HVAC systems, and marine applications. These flanges often work in tandem with lined pipes, plastic or stainless collars, and systems sensitive to corrosion, allowing for non-metallic contact with the process fluid. The loose flange design streamlines installation, alignment, and bolt tightening, making them particularly suitable for systems that experience thermal expansion, vibration, or have space limitations. Type 13 is a popular choice in these scenarios.
