For example, the professional technician, the responsible QC inspector, the experienced sales person, the rigorous document maker, the patient after-sales, etc. Their selfless devotion bring the customer good experience, and bring the company good reputation.Determination of Required Capacity
The aggregate capacities required for any vent valves, pressure-relieving valves, and/or vacuum-relieving valves to be provided should be determined as follows:
a)For thermal breathing and product movement, the rules given in API 2000 shall be followed. The required capacity as the result of the product movement into the tank API Std 650 mechanically-anchored flat-bottom tanks given in API 2000, shall be multiplied by the ratio of the absolute tank pressure to atmospheric pressure (14.7 lbf/in.2 absolute).
b)For supplemental safety pressure-relieving devices to take care of extra venting capacity required in case of external fire exposure, the rules in API 2000 shall be followed.Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API Std 650 mechanically-anchored flat-bottom tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).The company focuses on quality building, continuously create greatest value for customers, and has achieved good economic and social benefits. With strong financial strength, advanced management experience, perfect sales services, strict quality purchase management system and science overall marketing means. We are willing to go hand in hand with you for common development. To be the best service provider for iron & steel products globally is our goal.Tank cracks are common API Std 650 mechanically-anchored flat-bottom tanks defects, mainly including tank wall cracks, internal cracks, weld zone cracks. The reason for these defects may be that the defects not exceeding the standard existed in the early stage of API Std 650 mechanically-anchored flat-bottom tanks construction, which become obvious after the later use. Or in the process of using the API Std 650 mechanically-anchored flat-bottom tanks, the tank body material generated new defects due to corrosion, pressure, wear and other reasons, and tank cracks.
