Tesco Steel & Engineering is a premier manufacturer and exporter of Australia Standard AS2129 Table D Slip-On Flanges, crafted to deliver exceptional performance in industrial piping systems. Produced in our state-of-the-art Mumbai facility, these flanges are manufactured with advanced machinery and stringent quality control standards, ensuring precision, durability, and reliability for high-pressure and high-temperature applications. Slip-on flanges are ideal for projects where quick installation and alignment on pipelines are critical, making them a versatile choice for modern piping networks.
These AS2129 Table D Slip-On Flanges are also referred to as AS2129 Table D SORF, AS2129 Table D SOFF, and AS2129 Table D SO Flanges. Installation is straightforward: the flange is slipped over the pipe, aligned with the bolt holes, and then welded both inside and outside for a secure and leak-proof connection. This design allows for easy positioning on existing pipelines and ensures minimal stress on the piping system while maintaining a robust seal for high-pressure applications.
We manufacture these flanges in a wide variety of premium materials to meet diverse industrial needs, including stainless steel, duplex steel, alloy steel, carbon steel, low temperature carbon steel (LTCS), copper nickel, nickel, monel, inconel, hastelloy, and titanium. Each material is chosen for its superior corrosion resistance, mechanical strength, and ability to withstand extreme temperatures and pressures. This range ensures that clients can select the ideal material for specific applications, from offshore oil & gas to chemical processing and power generation.
Tesco Steel & Engineering exports AS2129 Table D Slip-On Flanges to multiple countries, including Australia, Germany, Italy, France, the United Kingdom, UAE, Saudi Arabia, and Qatar, serving a wide array of industries. These flanges are extensively used in offshore pipelines, petrochemical plants, water treatment systems, refineries, and high-pressure process piping. Backed by our superior manufacturing practices, advanced technology, and stringent quality assurance, these slip-on flanges provide long-lasting performance, safety, and reliability for critical piping infrastructure worldwide.
