GI Flanges: Types, Uses, and Pricing

 

Introduction

A GI flange (Galvanized Iron flange) is a critical component in piping and plumbing systems, used to connect pipes, valves, and equipment securely. These flanges are zinc-coated to enhance durability and corrosion resistance, making them ideal for water distribution, industrial applications, and structural connections.

Purpose of a Flange

A flange serves as a mechanical joint that allows for the easy assembly, disassembly, and maintenance of piping systems. It helps in sealing pipe connections, preventing leaks, and facilitating system modifications.

Types of Flanges

  1. Weld Neck Flange – Designed for high-pressure applications.
  2. Slip-On Flange – Easily installed by sliding over the pipe.
  3. Blind Flange – Used to seal the end of a pipeline.

Uses of GI Flanges

  • Water supply systems – Prevents corrosion in pipelines.
  • Plumbing applications – Ensures a secure joint in water pipes.
  • Industrial piping – Provides strength in high-pressure systems.
  • Structural applications – Used in building and mechanical supports.

GI Flange Price

The cost of 1 GI flange varies based on size and pressure rating. Approximate pricing:

  • Small-sized GI flange – ₹100-₹300 per piece
  • Medium-sized GI flange – ₹400-₹800 per piece
  • Large-sized GI flange – ₹1,000+ per piece

Full Form of GI Fittings

GI fittings stand for Galvanized Iron fittings, which include pipes, flanges, elbows, and tees coated with zinc to resist corrosion.

Where is GI Pipe Used?

  • Plumbing systems – Used for water transportation.
  • Construction industry – Provides structural support.
  • Irrigation systems – Used in agriculture for water distribution.
  • Industrial applications – Suitable for gas and fluid transportation.

Check Valve (Non-Return Valve): Types, and Pricing

  Introduction A check valve , also known as a non-return valve (NRV) , is a mechanical device that allows fluid to flow in only one direction, preventing backflow. It is commonly used in pipelines, water supply systems, industrial processes, and pumps to maintain directional flow and prevent equipment damage due to reverse flow. Check Valve Symbol The check valve symbol used in engineering diagrams consists of a valve body with an arrow indicating the permitted flow direction and a barrier preventing reverse flow. It is commonly seen in process flow diagrams (PFDs) and piping and instrumentation diagrams (P&IDs). Types of Check Valves (Non-Return Valves) There are several types of check valves (NRVs) designed for specific applications: Swing Check Valve – Uses a hinged disc that swings open with forward flow and closes when the flow reverses. Dual Plate Check Valve – Features two spring-loaded plates that automatically open and close with the...
