Welded vessels play a key role in most processes. However, few plants now have in-depth expertise in materials selection, fabrication and design of such vessels. As a result, plant staff often make errors that can be costly as well as compromise the suitability and life of the vessel. This three-part special report provides practical pointers that can help you avoid common mistakes and get the most appropriate, durable and cost-effective vessel.
Part 1 looks at a dozen important factors to consider in materials selection, including metal selection and appropriate use of corrosion allowances and coatings. It includes pointers gleaned from first-hand experiences that can help you avoid costly mistakes and delays.
Part 2 provides tips on how to avoid delays and achieve savings in the fabrication process. It also covers techniques that can improve vessel reliability and thus forestall costly repairs down the road.
Part 3 gets into design issues. It condenses the 5,000+ pages of the ASME Boiler and Pressure Vessel Code into a simple guide when specifying vessels, heat exchangers and tanks. It focuses on 10 key factors.
