What is gm upvc pipe 3/4″ sch-40 4meter ?

 

• A 3/4″ nominal diameter uPVC (un-plasticized polyvinyl chloride) pipe, designed to rating “Schedule 40” (Sch 40) wall thickness.

• “Schedule 40” means the wall thickness is specified such that the pipe can handle a certain working pressure at a certain temperature (for a given material) under standards.

• uPVC refers to rigid PVC, which is not flexible. People widely use it for water supply, irrigation, and chemical lines, depending on the compatibility with specific chemicals.

• The “3/4″” refers to the nominal pipe size (NPS) or the rough size category; the actual outside diameter will be slightly different.

Specification gm upvc pipe 3/4″ sch-40 4meter

• Material: uPVC (rigid PVC).

• Cell Classification of material (for PVC) typically is 12454-B or equivalent (for uPVC) in many catalogues.

Dimensions

• Nominal 3/4″ size has outside diameter (OD) ≈ 1.050″ (≈ 26.67 mm).

• Minimum wall thickness for 3/4″ Sch 40 is ~0.113″ (≈ 2.87 mm).

• The pressure rating at ambient (approx. 23 °C / 73 °F) for 3/4″ Sch 40 pipe is listed around 480 psi (~33.1 kg/cm²) in one table.

• Maximum operating temperature around 60 °C (≈140 °F) for standard uPVC Sch 40.

Chemical & Physical Properties

• Smooth inner bore, low friction loss for fluid flow.

• Good resistance to many chemicals: acids, alkalis, salts, halogens (depending on grade).

• Max temperature for typical uPVC is around 60 °C; beyond that the pressure rating must be derated.
