A573 grade 450 plates API Std 650 tanks
Service Conditions and Hydrogen-induced CrackingWhen the service conditions might include the presence of hydrogen sulfide or other conditions that may promote hydrogen-induced cracking effects, particularly near the bottom of the API Std 650 tanks shell at the shell-to-bottom connections, care shall be taken to ensure that the materials and details of construction of the tank are adequate to resist hydrogen- induced cracking. The Purchaser shall consider restricting the sulphur content of the material to be stored through thickness testing of the steel, laboratory surveillance tests, and the use of internal tank coatings to reduce the possibility of hydrogen-induced cracking.The API Std 650 standard published by the American Petroleum Institute (API) is designed to provide the petroleum industry with welded steel tanks for use in the API Std 650 tanks storage of petroleum products and other liquid products commonly handled and stored by the various branches of the petroleum industry.Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API Std 650 tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.In the actual welding of API Std 650 tanks, operators will use more arc-shaped plates for tailor-welding to better adapt to the larger volume of oil storage tanks. In order to effectively control the deformation of the welding seam of the API Std 650 tanks, a scientific and accurate prefabricated bottom plate is required. In the process of prefabricating the bottom plate of the oil storage tank, it is necessary to strictly follow the technical requirements for the construction of the oil storage tank. At the same time, it is also necessary to clarify the external dimensions according to its actual manufacturing standards so that it has sufficient shrinkage.Since its establishment, the company has been deeply supported and loved by customers with its unique business philosophy and business model.
