We know how frustrating it can be to deal with PVF suppliers who do "milk runs"—delivering a large group of customers' orders at once to save on costs—when you have tight deadlines and a crew itching to get back to work. At American Stainless, our schedule is your schedule. With our proven process, we do our best to ensure same-day service as well as on-time shipping that arrives on your schedule—not anyone else's. https://hubs.la/Q020y2p50 #AmericanStainless #AmericanStainlessAndSupply #PVF

Fire Safe Packing - How to prevent that small fires can turn into large fires. Last week I had an interesting discussion on the different testing standards that are being used, when evaluating valve packing. The discussion was around the different Fire Testing Standards, especially about API 589 and API 607. For me it was really interesting to discover that many people still believe that API 589 is old and was replaced by API 607. What people ignore is that API 607 was developed to address valve performance with a clear scope for quarter-turn valves and other valves with non-metallic seats. It was released by the API Downstream Segment . API 589 was written to address gland packing performance focusing mainly on API 600 gate valves that use, in most cases, a 5-Ring Stuffing Box. It was originally developed by EXXON in the early 1990s, after a big fire in one of their facilities. API took the findings and continued the research until the first Fire Testing Standard, identified as API 589, was released back in 1993. When looking into the different API standards that apply for valves and gaskets, we will find that nowadays 5 are being used, API 589, API 607, API 6FA, API 6FD, and API 6FB. The main challenge is that they have been released by different API segments and subcommittees, making clarifying very difficult. For my purpose, I just want to focus on the first two: Fact #1 API 589 requires the seat to be metallic while API 607 is based on non-metallic or soft seats. Fact #2 API 589 is much more challenging Fire Test Standard, as it focuses on the gland packing performance. The max. allowable leakage rate during the burn/cool-down process with API 589 is 10ml.min per NPS while at API 607 it is 100 ml/min per NPS (10x higher). Fact #3 The max leakage rate for API 589 is limited to 0.5ml/min per NPS while API 607 established that it is through leakage only. Fact #4 The allowable leakage rate for high pressure / post operation test established for API 589 10 ml/min per NPS while at API 607 it raises to 25 ml/min per NPS. Conclusion Just looking at these 4 facts, it is clear to me that API 589 is by far, a much more challenging Fire Testing Standard. What it shows is that passing API 607 does not mean that the valve will also pass API 589, while passing API 589 may secure passing API 607, as the leakage rate can be 10x higher. The reason is that API 607 does not only focus on the stem packing, it's focus is on the general performance of the valve including, for example, the bonnet gasket. These differences in testing show that a new, more precise Fire Testing Standard is needed, where these two standards may be unified to a new one that can provide clear and strict parameters for API 600 Gate Valves in general. The ideal scenario is to release it by unifying all the other standards and releasing it by just one single API segment or committee. Will it ever happen? That is really the big question inside the Oil & Gas Industry.

Different materials react differently to different mixing actions as well. At Onex, we use a variety of equipment – including a pan mixer, a rotary mixer, and a Hobart mixer – to ensure the right materials get the right mix. Knowing the importance of this step, we continue to invest in various mixer technologies. With millions of pounds of castable poured, the Onex team is prepared for virtually any material type and equipment requirements because we’ve seen first-hand how materials react differently to the various mixing “actions” and different mixer styles. #precast #refractory #furnace #madeinusa #americanmanufacturing #usmanufacturing
