Spilet Flange

About Spilet Flange

It sounds like you're referring to a Split Flange (sometimes misspelled as Spilet Flange). No worries heres the full breakdown:

---

Split Flange Overview

A Split Flange is a two-piece flange designed to clamp around a pipe or hose end, especially in hydraulic systems or situations where it's difficult to access the pipe ends to install a standard flange.

---

Key Features

• Made in two halves (split), bolted together around a fitting

• Used with flange adapters or ports with grooves

• Designed for easy installation and field repairs

• Often used in high-pressure hydraulic systems

• Conforms to standards like SAE J518, ISO 6162

---

Common Materials

• Carbon Steel (zinc-plated or phosphate-coated)

• Stainless Steel (304 / 316)

• Ductile Iron (less common)

• Aluminum (for low-pressure applications)

Corrosion Resistance and Durability

Each Spilet Flange is coated with a specialized anti-corrosive finish, protecting against rust even under extreme working conditions. This ensures longevity and reduces maintenance in environments exposed to water, oil, and gas. The metallic grey surface offers an added aesthetic while underpinning the robust construction typical of industrial standards like ANSI B16.5, DIN, and BS.


Precision Engineering for Versatile Use

With inside diameters ranging from 50 mm to 500 mm and outside diameters up to 720 mm, our Spilet Flanges are meticulously engineered for seamless integration into varied pipeline systems. Forged manufacturing and hydrostatic testing guarantee structural integrity and reliable performance across applications handling temperatures up to 600C and a wide span of pressures.
