Under the MS 762 : 1982, this range of pipes is categorized into various classes. Each classes serves difference purpose and

has various thickness with ability of withstanding the following working pressure:

• Class O General Purposed & Non Pressure Pipe.
(The Class O Standard is used as cable ducting, flush pipe and air conditioning water discharge outlet.)
• Class B 0.9MPa
• Class D 1.2MPa
• Class E 1.5MPa
• Class 6 The working pressure is refer to the norminal sizes
• Class 7 The working pressure is refer to the norminal sizes
