Galvanized malleable cast iron female-female sleeve

Galvanized malleable cast iron female-female sleeve

The Galvanized Malleable Iron Female-Female Sleeve is an essential junction fitting, designed to extend or connect two male threaded components of the same diameter with maximum safety and corrosion resistance. With its hot-dip galvanizing coating, this sleeve provides superior protection against oxidation, making it ideal for outdoor installations, humid environments, or networks carrying corrosive fluids. It is the ultimate durability solution for professionals who demand uncompromising performance and long life for their piping systems.

A Fitting Adapted to Multiple Requirements

The application of a zinc layer by galvanizing extends the field of use of this sleeve to more aggressive environments. It is ideally suited for water distribution, including drinking water, gas and steam networks, as well as for transporting any non-corrosive liquids or gases. This increased strength makes it indispensable for HVAC (Heating, Ventilation and Air Conditioning) systems and any installation exposed to weather or humidity. In addition, its characteristic silver-grey appearance is very popular in the field of decoration. Designers commonly integrate it to create industrial furniture in loft and vintage style, where the rawness, the quality of the material and the surface treatment offer a refined aesthetic and functional solidity.

Compliance with Standards and Robust Base Material

The manufacture of this sleeve adheres to very strict quality standards to ensure its reliability. The fittings are produced and tested in accordance with the international standards EN 10242 and ISO 49, ensuring perfect compliance and easy integration into existing systems. The base material is malleable cast iron EN-GJMB-350-10, as specified by EN 1562. This cast iron is known for its mechanical properties and resilience. The galvanizing treatment completes this robust base by adding a protective layer, improving the overall resistance of the fitting to stress and corrosion.

Total Reliability: Double Protection and Control

The performance of this sleeve is the result of a design focused on optimal reliability.

• The sleeve is equipped with two cylindrical female threads (Rp) that comply with ISO 7-1 (BSPT). These threads are designed to firmly accommodate the tapered (R) male ends, providing a compression junction essential to the sealing of the system.

• Hot-dip galvanizing creates a protective coating with a minimum thickness of at least 70μm (micrometers). This zinc layer acts as a sacrificial anode, actively protecting the cast iron from rusting and extending the durability of the fitting, even with slight abrasion.

• Quality assurance is maximum: each fitting is 100% tested for tightness at the end of production. This unit check is the guarantee of a defect-free, ready-to-use part.

Installation Guide for a Secure Connection

To exploit the potential of this galvanized sleeve, careful installation is recommended, especially in terms of the tightness of the threads.

• Surface Treatment: Despite galvanizing, it is always good to make sure that the two male threads to be connected are clean and dry before assembly.

• Sealant: It is crucial to apply a quality PTFE tape or a specific fluid gasket paste to the male threads that will fit into the sleeve, to ensure a perfect seal in conjunction with the Rp cylindrical thread.

• Adapted tightening: Tighten the sleeve tightly on both sides, without excess. Over-tightening could damage the threads or the galvanizing layer. Use a suitable wrench for precise torque.

• Alignment check: Ensure that the connected pipes are properly aligned to avoid undue lateral stress on the sleeve, which could compromise the tightness or structure.

• Industrial Furniture: The galvanized coating is inherently protective and does not require additional treatment for the furniture. You just have to appreciate its raw look and high resistance.
