Hydrotests (otherwise known as Hydrostatic or Pneumatic Tests) are used to measure the rate of expansion of the unit (pipeline or pressurized vessel such as tank, etc…) to determine if they can safely hold the amount of pressure the vessel is rated for. It ensures that the weld joints and flanges are fitted properly and confirms that the material used has the required strength to sustain the specified pressure. They are often used:   𝑭𝒐𝒓 𝑵𝒆𝒘 𝑷𝒊𝒑𝒆𝒍𝒊𝒏𝒆 𝑪𝒐𝒏𝒔𝒕𝒓𝒖𝒄𝒕𝒊𝒐𝒏: -      to test the structural integrity of a pipeline or segment of pipeline (or pressurized vessel such as a tank) following construction (or installation in the case of a tank) before commissioning to verify the safety and readiness for service.   𝑭𝒐𝒓 𝑳𝒆𝒂𝒌 𝑫𝒆𝒕𝒆𝒄𝒕𝒊𝒐𝒏: -      To test for a visible, measurable leak over a specified period of time. Bear in mind, for successful leak detection, we must inject our tracer gas at the beginning of the fill.   𝑾𝒉𝒆𝒏 𝒓𝒆𝒕𝒖𝒓𝒏𝒊𝒏𝒈 𝒂 𝒑𝒊𝒑𝒆𝒍𝒊𝒏𝒆 𝒐𝒓 𝒂𝒔𝒔𝒆𝒕 𝒕𝒐 𝒔𝒆𝒓𝒗𝒊𝒄𝒆 -      When returning a pipeline or asset to service after being dormant for a period of time   𝑺𝒐𝒎𝒆 𝑬𝒏𝒗𝒊𝒓𝒐𝒏𝒎𝒆𝒏𝒕𝒂𝒍 𝑪𝒐𝒏𝒅𝒊𝒕𝒊𝒐𝒏𝒔 -      When warranted under some environmental conditions, to help  prevent potential damage resulting from leaks using water in a hydrotest minimizes damage resulting from leaks or ruptures.   𝐋𝐞𝐠𝐚𝐜𝐲 𝐏𝐢𝐩𝐞𝐥𝐢𝐧𝐞𝐬 𝐨𝐫 𝐀𝐬𝐬𝐞𝐭𝐬 - For pipe sections manufactured before 1970 using low-frequency electric resistance welding (LFERW) and lap welding (LW), hydrotesting is a valuable tool. Some factory-welded seams in these pipes have shown susceptibility to failure.   #hydrotesting #hydrostatictest #hydropressure #pneumatictesting #pipelineleakdetection #pipelineintegrity

Do you know that pipeline permits could take up to 10 years? So, commissioning existing dormant facilities is an option that requests testing, upgraded technologies, and re-engineering.
