Differences between ISO and TA-Luft ISO 15848 “Measurement, test and qualification procedures for fugitive emissions” the entire valve, including seals, will be subjected to type testing. The requirements of the ISO type tests are very specific and detailed: - Part 1: A distinction is made here between 3 tightness classes: A, B and C. Class A having the smallest environmental leakage. Part 2: Leakage is tested at room temperature without mechanical effects utilising a helium leak detection test. Pressure, temperature, endurance & tightness measures must be met. Australian Pipeline Valve has a full range of ISO 15848 certification. TA-Luft only deals with the sealing system of the stem passage. No third party witness is needed. The TA-Luft test qualifies only a “high-quality sealing system”. TA-Luft is considered to be complied with if metal bellows with a safety packing or similar sealing systems are used; in accordance with VDI 2440. There is neither requirements as to the number of mechanical cycles not the number of thermal cycles. Many valve manufacturers like to publish the TA-Luft logo but it often only means the seals they use were TA-Luft certified! Simply using “TA-Luft packings” does not guarantee long-term leak tightness. Too many other factors play a significant role in sealing system, such as the stem surface finish and the tolerances dimensions between the gland and the stem. #valvetechnology #valvemanufacture #valves

API 6A Valve Seat Seals Peek Seal Ring A peek o-ring, on the other hand, is a type of o-ring made from peek material. O-rings are mechanical seals that are used to prevent the leakage of gases or liquids. https://buff.ly/3ZwizOT #API6AValve #API6AWELLHEADEQUIPMENT #pipefittings #highendpetroleum #mudmanifold

Eddy current testing. Eddy current testing (ECT) is a non-destructive testing (NDT) method that can inspect the condition of chiller tubes to identify problems early and prevent leaks and failures. ECT can be used on condenser and evaporator tubes, and can even inspect through coatings and paint

FAQ Friday Q. What is the recommended span for pressure gauges in pump applications? A. ASME B40.100 guidelines recommend keeping the normal operating pressure between 25% and 75% of full scale. https://hubs.li/Q02KBcHz0

Well.. this is my personal feeling. I feel the ISO 15848-1 standard for fugitive emission test imposes excessively stringent requirements particularly for control valves. As this standard is exclusively for type testing, the following concerns arise: Excessive cycling: Prototypes undergo an inordinately high number of cycles, despite the limited valve stroke. Where on-off valves are to undergo far less numbers of cycles. Extreme temperature cycling: The prescribed temperature range from ambient to test temperature is overly demanding. Disproportionate leakage requirements: The leakage limits for AH class valves are equivalent to those for metallic bellow sealed valves, which is overly strict for gland packing-only designs. Incongruent production testing: Following successful type testing, the production test (ISO 15848-2) permits significantly higher leakage rates. I am unable to understand the correlation between these leakage rates, as typically, leak rates are expected to increase with temperature. Any thoughts?” #ISOFE #FugitiveEmission #Controlvalves #ISO15848

To track the tanks and verify that they satisfy ASME standards, one customer had to mark filtration tanks with the ASME logo and an ASME Certification Number. The tanks sat inside a semi-trailer where there was no space for an equipment cart and no nearby power source. Their current method involved hand stamping, a process which was not only time-consuming and perilous in confined spaces, but also excessively loud. The customer approached us for a more streamlined solution. Learn more: #pinmarking #filtration #tanks #ASME
