API 650 welded aluminum storage tanks roof support legs sleeves
The internal floating plate of internal floating roof tank of API 650 tank is different from that of open floating plate of API 650 welded aluminum storage tanks External floating roof tank of API 650 tank, so it is impossible to have rain and snow load.
The hardness of the welds contacting these environments, including the heat-affected zones, shall be considered. The weld metal and adjacent heat-affected zone often contain a zone of hardness that is well in excess of a value of 22 on the Rockwell C scale and could be expected to be more susceptible to cracking than would unwelded metal. Any hardness criteria shall be a matter of agreement between the Purchaser and the API 650 welded aluminum storage tanks manufacturer and shall be based on an evaluation of the expected hydrogen sulfide concentration in the product, the possibility of moisture being present on the inside metal surface, and the strength and hardness characteristics of base metal and weld metal.
The manufacturing requirements of bottom plate of vertical metal tank, API 650 welded aluminum storage tanks are as follows: 1. In order to compensate welding shrinkage, the layout diameter of tank bottom is 5-2mm than the design diameter; 2. The butt joint of edge plate of tank bottom shall be machined automatically or semi-automatically; 3. The distance between any two adjacent welding joints on the tank bottom plate and the distance between the butt joint of edge plate and the longitudinal weld of bottom ring wall plate shall not be greater than 200 mm.
Corporate mission: to provide high quality steel products API 650 welded aluminum storage tanks and services to global customers.Strategic goal: to be the leading steel materials supplier in the world.Enterprise core values: people-oriented, customer first, quality oriented, comprehensive and open, continuous innovation.Customer first is to always put the satisfaction of customer needs first. The key point is "customer centered". We should consider what customers need us to do, what we have done for them, what else we can do for them.
Management information and high efficiency. Because of the rapid flow of API 650 welded aluminum storage tanks goods, container multimodal transport and "door-to-door" transport, it is required that the port must have a modern information network, so that it can have the comprehensive capabilities of all-weather access, rapid loading and unloading, customs clearance, collection, distribution, storage and transportation
The after-sales service department will pay return visit to each customer by call or email, report problems found during the return visit in time, and discuss with the production and quality inspection center to propose effective solutions and follow up in a timely manner, so as to ensure the benefits each customer are fully guaranteed, and to provide customers with more value-added services.
