3. Schedule
Refers to the wall thickness of PVC pipes. Common schedules include 40 and 80.
4. Pressure Rating
Indicates the maximum pressure a pipe or fitting can handle, typically measured in PSI.
PVC Pipe-Specific Terms
1. Diameter
The width of the pipe’s interior or exterior, crucial for flow rate calculations.
2. Wall Thickness
Determines the pipe’s strength and pressure-handling capacity.
3. SDR (Standard Dimension Ratio)
A ratio of pipe diameter to wall thickness, affecting its pressure capacity.
4. Pipe Length
The measurement of the pipe’s size, typically available in standard lengths like 10 or 20 feet.
Fitting-Specific Terms
1. Coupling
A fitting used to connect two pipes of the same size.
2. Elbow
Changes the direction of pipe flow, commonly at 90° or 45° angles.
3. Tee
A fitting that allows three pipe connections, forming a “T” shape.
4. Reducer
Connects pipes of different sizes to regulate flow.
Connection Methods and Related Terms
1. Solvent Welding
A chemical process bonding pipes and fittings by softening their surfaces.
2. Threaded Connection
A method where male and female threads screw pipes and fittings together.
3. Gasketed Joints
Sealed connections using rubber gaskets for leak-proof results.
Material Properties and Features
1. Tensile Strength
The maximum stress a PVC pipe or fitting can withstand before breaking.
2. UV Resistance
