Steam hoses can be used for a variety of applications. Some common industrial uses include sterilization processes and lubrication. To handle steam's high temperatures, they must be durable and safe.
It can be difficult and time-consuming to choose the right pipe size for a Steam Pipeline. Many graphs, charts and tables are available to help with this process. There are also empirical formulae that can be programmed in a spreadsheet to make quick calculations.

The steam hose is an important component in most industrial processes. The right hose can improve productivity and efficiency by reducing downtime. The right hose is rated according to the temperature and pressure that your process will operate at. It will also be compatible chemically with the materials that are being transported. It will be flexible, and able to withstand bend stresses. It will also be able to resist abrasion and heat.
To ensure the hose is safe for use, it should be properly cleaned and stored between uses. It is also recommended that the hose be regularly inspected for deterioration, especially when it is not in use. The hose can be inspected for cracks or tears to prevent injury or death due to leaks.
If you find a crack or tear in the hose it should be replaced. Be sure to check the hose for popcorning. This is a condition where the inner tube gets damaged by water vapor cooling while the hose was not in use. This can result in clogging the hose and eventually cause it to burst. To avoid popcorning, it is advisable to drain the hose after each use. Additionally, the hose should be stored in a rack or on a pallet to minimise damage.
How to choose hose steam
Steam hoses can become very hot and should not be handled by anyone other than fully-qualified distributors and fabricators. They should be inspected on a regular basis for gouges, kinks, loose clamps, cover damage and exposed reinforcement. Also, they should be re-tightened after every use and a static check performed to ensure proper operation. The couplings for the hoses should be bolt type, not crimp fittings. They should be tightened using calibrated torque tools, not impact wrenches.
Pipe sizing for saturated and superheated steam applications is critical to avoid system failure. To correctly size the pipe, it is important to know the pressure drop and the steam velocity. There are several graphs, tables and slide rules available to help with the calculation, but one method that has stood the test of time is the 'pressure factor' method.
The 'pressure factor' method is an easy to understand way of calculating the required pipe size for a specific application. It uses a set of values which can be interpolated in order to get the desired result. For example, if the steam flow rate is 270 kg/h, then it would be necessary to select a pipe of size 50 mm. Equation 10.2.8 can be used to calculate the pressure drop, and the velocity after determining the pipe size.

Steam can cause damage to a piping system when it is released. This is especially true if your pipe is long, thin, or has sharp bends. Water hammer can be caused by the sudden release steam into a small space. The resulting pressure can cause damage to the insulation, and may even break it.
Steam pipe systems should be sized for velocity and pressure drop. The formulas found in Sections 10.2.9 and 10.2.10 are a good way to determine the size of a pipe. However, there are also empirical formulae that can be programmed into a calculator or spreadsheet. These formulae will give results that are similar to the pressure factor method.

This piping should be re-insulated, and steam traps installed to drain condensate from the line. Install steam traps at low sections of pipe and at any changes in direction such as a 90 degree bend. Steam traps should be sized correctly to prevent condensate overflow. This will help to prevent damage and increase operator safety.
