Tiiveystestaus

Tiiveystestaus, also known as "tightness testing" in English, is a method used to assess the integrity of a container or vessel, such as a pipeline, tank, or vessel, by applying a controlled pressure to detect any leaks or weaknesses. The process involves gradually increasing the pressure inside the container until a predetermined limit is reached, or until a leak is detected. The pressure at which a leak occurs is known as the "burst pressure" or "leak pressure."

Tiiveystestaus is commonly used in the oil and gas industry, as well as in other industries that involve the storage and transportation of hazardous materials. The test can be performed on new containers or on existing containers that have been in service for some time. In the latter case, the test is often used to assess the condition of the container and to identify any areas that may be at risk of failure.

The test is typically performed using specialized equipment, such as a pressure testing machine or a hydraulic testing machine. The equipment is designed to apply a controlled pressure to the container and to monitor the pressure and any leaks that may occur. The test is usually performed under controlled conditions, such as in a laboratory or a testing facility, to ensure the safety of the personnel and the environment.

The results of the tiiveystestaus are used to determine the integrity of the container and to identify any areas that may require repair or replacement. The test can also be used to verify the design and manufacturing quality of the container. In some cases, the test may be required by regulatory authorities or industry standards to ensure the safe operation of the container.
