PVC Pressure Pipes Guide

PVC Pressure Applications

Water Service.

Hot and Cold Water Distribution.Plastic pressure piping is used for many industrial processes, in heating and cooling systems, fire protection installations, gas distribution, and for water supply and distribution.

Potable water applications include cold water services from wells or water mains up to the building as well as hot and cold water distribution piping within buildings.

ABS, PE and PVC materials are all available with 73°F stress rating for use in pressure piping. PE piping is used extensively for cold water service lines and water distribution systems outside the building. Its low temperature flexibility make it especially suited for use in applications where temperature of 35°F and lower will occur.

The maximum temperature at which PE has an HDS rating is 140°F.

Materials with HDS Ratings for Higher Temperatures

Chlorinated Poly (Vinyl Chloride) (CPVC), and cross-linked polyethylene (PEX) materials are available that are rated for long term service at 180°F as well as for cold water applications. Hot and cold water distribution system piping made from these materials has a working pressure rating of 100 psi at 180°F. These systems are tested at 150 psi at 210°F for at least 48 hours to assure integrity at those condition, which may develop in the event the water heater controls malfunction. Thus, such materials are suitable for hot water distribution where water heaters are installed with relief valves set at 150 psi, 210°F.

All plumbing codes require the use of piping having the 100 psi @ 180°F rating for both the hot and the cold water portions of the water distribution system.

Some other applications.

Fire Sprinkler Piping.

Swimming Pool Piping.

Chilled Water Systems.

Irrigation.

Ice Melting.

Radiant Floor Heating.

Precautions for using PVC pressure pipe

PVC pressure pipe is a safe and efficient means of conveying water, sewage, and other fluids under pressure. However, as with all types of piping, there are certain safety precautions that must be observed when working with PVC pressure pipe.

Some of the most important safety precautions to keep in mind when working with PVC pressure pipe include:

- Always wear proper personal protective equipment (PPE), including gloves, safety glasses, and hearing protection, when working with PVC pressure pipe.

- Be aware of the potential for static electricity buildup when working with PVC pressure pipe. To help prevent static discharge, always ground yourself and your work area before beginning work.

- Never use power tools or machines to cut, drill, or grind PVC pressure pipe. Doing so can create sparks that could ignite flammable vapors present in the air around the work area.

PVC pressure pipe is a safe and reliable means of conveying water and other fluids under pressure, but there are a few things to keep in mind when using it.

1. Make sure the pipe you're using is rated for the fluid and operating conditions you're subjecting it to.

2. Use only fittings that are specifically designed for use with PVC pressure pipe. Never use improvised fittings or those designed for use with other types of pipe.

3. Always support the weight of the pipe, even if it's just resting on a shelf or in a cabinet. Pressure from the weight of the water inside the pipe can cause it to collapse if it's not supported properly.

4. Never use PVC pressure pipe that has been damaged in any way, such as by being bent, kinked, or crushed. Even a small amount of damage can reduce its strength and cause it to fail under pressure.
Grades of PVC pressure pipes

PVC pressure pipes are manufactured in two grades:

- Grade 1 (also called Type I) is used for irrigation and other non-pressure applications.

- Grade 2 (also called Type II) is used for potable water, raw water, and industrial applications. It can also be used for irrigation if it meets certain standards.

PVC pressure pipes are manufactured from a rigid PVC compound with a nominal cell classification 12454B as defined and described in ASTM D1784. The pipe dimensions are defined in ASTM D2241.

PVC pressure pipes are used in a variety of applications, from water mains and irrigation systems to sewer lines and septic systems. PVC pressure pipes are categorized by their diameter and their wall thickness. The most common sizes are:

3/4-inch (19 mm) diameter pipe with 1/16-inch (1.6 mm) wall thickness.

1-inch (25 mm) diameter pipe with 3/32-inch (2.4 mm) wall thickness.

1 1/4-inch (32 mm) diameter pipe with 1/8-inch (3.2 mm) wall thickness.

1 1/2-inch (40 mm) diameter pipe with 5/32-inch (4.0 mm) wall thickness 2 inches(50mm) PVC pipe, 3 inches(80mm), 4 inches(100mm) PVC Pipe, 6 inches(150mm), 8 inches(200mm).
What are the advantages of PVC pressure pipes

PVC pressure pipes are one of the most commonly used types of pipe in the world. They are made from a strong and durable plastic that can withstand high pressures, making them ideal for a wide range of applications.PVC pressure pipes are often used in the construction industry, as they can be used to transport water, gas and other fluids around a site. They are also commonly used in domestic settings, as they can be used to connect appliances to mains water and gas supplies.PVC pressure pipes are very versatile and can be used in a variety of different ways. Here are just some of the advantages of PVC pressure pipes:

1. They are strong and durable – PVC pressure pipes are made from a tough and durable plastic that can withstand high pressures. This makes them ideal for use in a wide range of applications, both commercial and domestic.

2. They are easy to install – PVC pressure pipes are relatively easy to install when compared to other types of pipe. This is because they can be cut to size using standard tools, and then glued or welded together using standard fittings.

3. They have a long lifespan – PVC pressure pipes have a long lifespan andPVC pressure pipes are strong, durable and have a long service life. They are resistant to corrosion, abrasion and most chemicals. PVC pressure pipes are also lightweight, making them easy to transport and install.
