The Ministry&#039;s periodic inspection and reassessment report formats for LPG tanks have been mandatory since July 18, 2025. AES Innovation organizes this inspection together with its authorized partner equipment inspection organization; this organization prepares the periodic inspection report. AES Innovation&#039;s own accreditation scope (AB-0631-M) is the periodic inspection of electrical installations.

Loss of wall thickness due to corrosion or a faulty safety valve can lead to gas leaks, fires, and BLEVE-type explosions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Periodic inspections prevent these catastrophic scenarios by verifying tank integrity and safety systems, and documenting compliance with regulations.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is checked?<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Corrosion, pitting, and cracks in the shell and weld seams.<\/li><li>Ultrasonic wall thickness (UT) measurement<\/li><li>Safety valve opening pressure and calibration.<\/li><li>Pressure gauge, level and temperature indicators.<\/li><li>Grounding and equipotential connections<\/li><li>Cathodic protection potential in buried tanks.<\/li><li>Gas leak detection and filling\/emptying fittings<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Methods and Non-Destructive Testing<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Pressure vessel inspection includes internal and external visual inspection, ultrasonic wall thickness measurement (UT), and hydrostatic pressure testing as needed. Safety valves are verified on a test bench according to their opening pressure. Cathodic protection measurements are also performed in buried tanks due to the high risk of corrosion.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Legal Basis and Period<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">LPG tanks, as pressurized equipment, are subject to periodic inspections under Law No. 6331 and Annex III; these inspections are carried out by authorized personnel and documented with a report prepared by them.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Common Nonconformities<\/h2>\n\n\n\n<ul class=\"wp-block-list\"><li>Widespread corrosion and paint loss on the exterior surface.<\/li><li>Safety valve that has outlived calibration or is leaking.<\/li><li>Insufficient\/inadequate grounding.<\/li><li>Insufficient cathodic protection potential in buried tanks.<\/li><\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How often is a hydrostatic test performed on an LPG tank?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">This is determined according to the tank type and regulations; the tank condition is evaluated during the annual inspection, and pressure tests are assessed at longer intervals.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do buried tanks require additional checks?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes; cathodic protection measurements should be carried out due to the risk of corrosion.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is a safety valve critical?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">It is the last safety barrier protecting the tank from excessive pressure; the opening pressure must be verified.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Document Your Security<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">For pressure vessel and LPG tank inspection <a href=\"https:\/\/aesinn.com\/en\/muayene-periyodik-kontrol\/mekanik-ekipman-muayeneleri\/\">Mechanical Equipment Inspections<\/a> Check out our page; <a href=\"https:\/\/aesinn.com\/en\/periyodik-kontrol-zorunlu-mu-yasal-sureler\/\">mandatory periodic inspection<\/a> Check out our guide.<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\"><div class=\"wp-block-button\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/aesinn.com\/en\/iletisim\/\">Get a free quote \u00bb<\/a><\/div><\/div>","protected":false},"excerpt":{"rendered":"<p>Short answer: Liquefied petroleum gas (LPG) storage tanks are pressure vessels that store flammable gas under pressure.
