Cylinder Identification |
Cylinder & its color:
SIGAS uses a unique color paint code to identify Specialty Gas cylinders. Below are the highlights of our cylinder packaging and color code.
- All Mixture gas cylinders bodies are painted uniformly lilac blue and covered with a protective plastic net.
- A color coded shoulder indicates the product nature (e.g. Red for flammable mixture, Yellow for Toxic, Pure Orange
for corrosive, and white for Inert) All High Purity / Carrier Gases cylinder bodies are painted with already existing color code of SIGAS ( Green for O2) with 2” band painted Lilac Blue below the shoulder of cylinder (e.g. one 2” band for Research grade, two 2” band for Instrument/Carrier grade and three 2” band for UHP/Zero Grade.
