Understanding Our Pipe Codes

Our multilayer pipe models follow a simple and consistent labeling format to help identify the pipe's dimensions, application, and welding method.

Example: 12 16 H-B

This code can be interpreted as:

• 12 – Inner diameter: 12 mm

• 16 – Outer diameter: 16 mm

• H – Application: Hot water / Heating pipe

• B – Welding method: Butt-welded
   

Pipe Classification Guide

By Application

• C = Cold Water Pipe

• H = Hot Water / Heating Pipe

• G = Gas Pipe
   

By Welding Method

• A = Overlap Welded

• B = Butt Welded
   

Each code suffix indicates a unique pipe type. For example:

• C-B → Cold Water Pipe, Butt-Welded

• H-B → Hot Water Pipe, Butt-Welded

• G-B → Gas Pipe, Butt-Welded

 
Butt-welded pipes are known for their smooth inner surfaces, minimal risk of delamination, and excellent performance under pressure — especially in heating and gas distribution systems.

Pipe Colors

• Pipe color is customizable based on your preference or installation requirements.
  Common choices include:

  • Blue for cold water

  • Red for hot water

  • Yellow for gas
