# How do you size a steam pipe?

## How do you size a steam pipe?

Two principal factors determine pipe sizing in a steam system: 1. The initial pressure at the boiler and the allowable pressure drop of the total system. The total pressure drop in the system should not exceed 20% of the total maximum pressure at the boiler. This includes all drops — line loss, elbows, valves, etc.

## What pipe is used for steam lines?

What is the typical pipe material for steam systems? Pipes for steam systems are commonly manufactured from carbon steel to ASME B 16.9 A106. The same material may be used for condensate lines, although copper tubing is preferred in some industries.

Should steam pipe be Schedule 40 or 80?

Piping also comes in different schedules (or wall thicknesses). The schedule or thickness would be schedule 40 or 80. The wall thickness for typical 6 inches schedule 40 increases from 0.280 inches to 0.432 inches for schedule 80. This tends to erode condensate piping over time.

### What is a good steam flow rate?

Steam and Water mix < 25 < 82
Superheated Steam 35 – 100 100 – 300
