API standard 650 self-anchored tanks erection

The welded API 650 tank in various sizes and capacities for internal pressures approximating atmospheric pressure (internal pressures not exceeding the weight of the roof plates), but a higher internal pressure API standard 650 self-anchored tanks is permitted when additional requirements are met.

After comprehensive and professional training such as customer service, the customer service team has more strict discipline in the management of customer service team to ensure that customer service personnel respond to customers with a professional attitude. A process supervision system has been set up to let each customer supervise the process of the system with us.

Both parties shall confirm the API standard 650 self-anchored tanks material object and the quality of the products, confirm the reasons for the defects and the quality of the products, and sign the quality inspection agreement. Major quality objections shall be reported to relevant leaders in a timely manner, and shall be discussed and solved with the API standard 650 self-anchored tanks steel plant.

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 standard 650 self-anchored 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.
