Steam boilers are boilers that boil steam by boiling any liquid. Steam boilers they are generally used to obtain steam from water. Water is boiled and heated when heated. The water vapor spreads to a much larger volume than the liquid of the water. When the water is boiled in an open area, it reaches to a volume of 1.700 times the volume of the liquid. However, since the closed containers do not allow such expansion, the steam that wants to expand pressurizes the inner surface of the container. The more this steam, the higher the pressure. However, there is a certain pressure limit has. If pressure crosses this limit, there is a risk of explosion. In order to prevent the boiler from exceeding the specified pressure safety limit, all steam boilers have a safety valve that throws out excess steam.

In the first steam boilers, the pressure amount rarely exceeds the 1.7 of the atmospheric pressure. Until 1860's years, production techniques were not enough, so 3 floor was not exited too much. In the 1900, 20 has reached the atmosphere.

Nowadays, boilers with pressure between 40 and 50 atmosphere are widely used. In the industry there are pressure steam boilers on the atmosphere of 100.

Accordingly, inspection and controls of steam boilers must be carried out at least once a year. It is also a must for these inspections and inspections to be carried out by mechanical engineers, machine technicians or high technicians. Otherwise, neither the inspection and the inspection will have a validity, nor will the edited reports have any meaning.

During the periodic inspections of steam boilers, the following legal regulations must be taken into account:

  • Regulation on Pressure Equipment published in 2007
  • Portable Pressure Equipment Regulation published in 2012
  • Simple Pressure Vessels Regulation published in 2006

In addition to these legal regulations, the standards to be taken into consideration are:

  • TS 2025 Steam boilers operation - General rules of inspection and maintenance
  • TS EN 13445-5 Pressure receptacles - Non-contact - Section 5: Inspection and testing

The principle of performing hydrostatic tests is essential in periodic inspections of steam boilers. During tests, if there is no provision contrary to the standards, 1,5 solid surplus of operating pressure is applied in the boilers.

The TÜRCERT certification body, on the other hand, offers conformity assessment, certification and training services. testing and inspection services also gives. Please do not hesitate to contact the TÜRCERT certification body, experienced managers and employees for more information and inspection of the steam boilers.
