How grooved joint used in fire protection fittings?

Mar 29, 2024 | News

Fire protection fittings play a crucial role in ensuring the effectiveness of fire protection systems. These elements are indispensable for establishing a resilient firefighting framework.

Sprinklers and Valves

  • Fire sprinklers are sophisticated mechanisms designed to automatically discharge water upon sensing the presence of heat generated by a fire. Available in a range of configurations such as pendant, upright, sidewall, and concealed varieties, these systems are pivotal in fire suppression efforts. Each type has specific applications and installation requirements.
  • Gate valves serve as pivotal components for regulating water flow within fire protection systems. Positioned usually at the primary water supply connection, and they empower firefighters with the ability to swiftly halt water flow for maintenance or in emergency situations.

Pipe Fittings

  • Grooved joints and Adapters: These fittings connect different sections of pipes in fire protection systems. They ensure a secure and leak-free joint between pipes.
  • Mechanical tees facilitate the extension of pipelines by enabling the attachment of supplementary sprinklers or related apparatus. Butterfly valves, operating on a quarter-turn mechanism, are instrumental in managing water flow, particularly in wide-diameter pipes, offering rapid shutoff functionalities. Check valves are strategically installing to thwart backflow, ensuring that water moves in a singular direction exclusively. They maintain pressure and prevent contamination.

How grooved pipe connections applied in fire protection fittings?

Grooved joints are widely using in fire protection systems due to their efficiency and reliability. Let’s explore how they are applied:

Grooved Joints and Fittings

A grooved coupling serves as the joint fitting that connects grooved pipes and various components like elbows, tees, and reductions.
These unions comply with NFPA 13 Standards, playing a vital role in fire protection services. Grooved couplings and accompanying accessories need to bear ULFM (Underwriters Laboratories and Factory Mutual Engineering Corp.) certification and approval for use in fire protection contexts.

Creating Grooves in Pipes

To allow grooved fittings to securely grip the pipe, the pipe itself needs grooves. Two common methods are used:

  • Roll Groove Pipe: An indentation is pressed into the pipe near its end. This allows grooved fittings to slip over the pipe and fit into the groove. Roll groove pipe maintains pipe thickness, making it more corrosion-tolerant.
  • Cut Groove Pipe: Cutting into the pipe removes a portion of the wall, resulting in a thinner but smooth interior. While cut groove pipe is more susceptible to corrosion, its smooth inside prevents water from sitting and corroding the pipe.

Elbows and Tees

Elbows allow bends at various angles (e.g., 90 degrees, 45 degrees, 22.5 degrees, and 11.25 degrees). By combining two 90-degree elbows back-to-back, we can create a “swing joint” and achieve any desired angle by adjusting the elevation of the joined pipe.

Grooved Coupling

Remember that fire protection fittings are essential for safeguarding lives and property. Their proper selection, installation, and maintenance are vital for effective fire suppression systems.
