Pneumatic Tubing Size

Pneumatic tubing size

Typically, you can multiply the capacity of straight-line piping by 1.5 for loop type compressed air distribution systems. For example: If a 2” aluminum pipe is rated for 500 CFM at 125 PSI, that same length of pipe in a loop system would be rated for 750 CFM at 125 PSI.

What are the most frequently used materials in pneumatic pipes?

Polyethylene (PE) is widely used with pneumatics, and its semi-rigid nature permits use with push-to-connect fittings without clamps. It is also one of the lower-cost plastic materials and satisfies many requirements that call for inexpensive, lightweight tubing. In fact, PE tubing is so light, it floats in water.

How is pneumatic fitting size measured?

The sizing of a pneumatic fitting is defined by the size of vessels it connects to. Tubes, hoses, and pipes are sized based on inside diameter (ID) and outside diameter (OD), measured in inches (in) or millimeters (mm). A fitting designed to connect to a tube with a 2" OD is rated as a 2" OD fitting.

How do I calculate pipe size?

The equation for pipe diameter is the square root of 4 times the flow rate divided by pi times velocity. For example, given a flow rate of 1,000 inches per second and a velocity of 40 cubic inches per second, the diameter would be the square root of 1000 times 4 divided by 3.14 times 40 or 5.64 inches.

What is pneumatic tubing made of?

Common pneumatic tubing materials include polyurethane, nylon, polyethylene, and polyvinyl chloride (PVC). Tubing sizes will depend on your application requirements. Air systems and applications will have different flow requirements and tube sizes from fluid handling systems.

Can you use PVC for air line?

The use of PVC pipe is common but not recommended for use with compressed air. The biggest reason is because it is against OSHA Regulations to utilize PVC and plastic pipes in the United States for compressed air usage. It is, however, often used because it is readily available, inexpensive, and easy to install.

What type of pipe is used for air lines?

The current compressed air piping material of choice is aluminum. Lightweight but durable and resistant to corrosion, it is easier to install and modify than most alternatives. Typically, aluminum piping arrives ready to install and requires few tools to set up.

What is BSP size?

BSP Thread Size	Outside Diameter mm / inch	TPI
1 Inch BSP	33.25 mm / 1.309"	11
1-1/4 Inch BSP	41.91 mm / 1.650"	11
1-1/2 Inch BSP	47.80 mm / 1.882"	11
2 Inch BSP	59.61 mm / 2.347"	11

How is NPT size measured?

To determine the NPT size, with a caliper, measure the diameter of the 2nd or 3rd thread on your pipe, fitting or valve as shown below. Find the caliper measurement in the chart and cross reference the nominal NPT pipe size. Don't get confused, the actual measurement is not the same as the NPT pipe size.

How do I determine thread size?

Use a pitch gauge. And check the thread against each form until you find a match. Some fractional

What is line sizing criteria?

When sizing lines the sizing criteria shall be minimum life cycle cost, this may include evaluation of functional requirements, cost of piping, weight, CO2-tax, energy costs, mechanical and process limitations, expected lifetime of piping, maintenance cost etc.

What is meant by line sizing?

WHAT IS LINE SIZING ? Line sizing is one of the most important and critical activities done by a process engineer for any project. Piping is a major cost component in any process plant and it may vary between 5-15% of the total plant investment and optimum design may result in considerable cost reductions.

How do I calculate pipe thickness?

Answer: Having the inside dimensions (ID) and the outside dimensions (OD) will allow you to figure out the wall thickness on tubing. You would need to subtract the ID from the OD and then divide by two. This number is the wall thickness.

What is pneumatic tubing used for?

Pneumatic tubes (or capsule pipelines, also known as pneumatic tube transport or PTT) are systems that propel cylindrical containers through networks of tubes by compressed air or by partial vacuum. They are used for transporting solid objects, as opposed to conventional pipelines which transport fluids.

What is a pneumatic fitting?

Pneumatic fittings provide the essential link between tubes, hoses and other components in a pneumatic system. Air fittings feature tighter seals and have lower pressure requirements than hydraulic fittings and are typically offered in various connector types.

What is a pneumatic line?

An air line is a tube, or hose, that contains and carries a compressed air supply. In industrial usage, this may be used to inflate car or bicycle tyres or power tools worked by compressed air, for breathing apparatus in hazardous environments and to operate many other pneumatic systems.

What type of pipe is best for compressed air?

Ideal plastic pipes for piping compressed air are made of acrylonitrile butadiene styrene (ABS). Polyethylene (PE) piping and high-density polyethylene (HDPE) piping are also good choices for compressed air applications. PVC is not recommended and is an OSHA violation if used.

How much psi can PVC take?

Most consumer air compressors only compress to around 125-175 psi. This doesn't seem like a whole lot, especially when even the smallest size PVC pipe can generally handle anywhere between 300-600 psi.

How many PSI is PVC rated?

PVC has a derating factor of 0.31 at 130°F (54.4°C), making it pressure rated up to 71.3 psi at that temperature (230 psi x 0.31 = 71.3 psi). CPVC has a derating factor of 0.57 at 130°F (54.4°C), making it pressure rated up to 131.1 psi at that temperature (230 psi x 0.57 = 131.1 psi).

What is best to use for air lines?

Aluminum is lightweight for easy handling and resists corrosion and leaking, saving companies money. Aluminum pipes are also easier to install and modify than other pipe types, as they don't require threading or soldering. They are highly recommended for clean air applications.
