API 650 floating-roof tanks inspecting requirements

API 650 Application As described by the American Petroleum Institute, the fabrication and installation of our surface welded API 650 floating-roof tanks steel storage tanks is normally used in industrial applications. In general, our standards for industrial on-site installation of storage tanks are established according to API 650, API 620 and API 12D.

Aftershock Level Earthquake (ALE)
This design case shall be applicable only when regulations or project documents specifically require the tank system to be designed or evaluated for aftershocks.
If the outer tank is not designed as a secondary containment (i.e. it serves as vapor barrier and pressure boundary only and is not constructed of API 620 material suitable for the inner tank API 650 floating-roof tanks), then no design or evaluation for ALE is required by these provisions for the inner or outer tank.

The coating on the outer wall of API 650 floating-roof tanks can not only reflect light but also prevent corrosion. Different coatings for oil tanks have different reflective properties, and the reflective performance of coatings is expressed by reflection index. For example, the reflection index of white coating is 90.0, that of sky blue coating is 85.0, and that of light gray coating is 57.0. It can be seen that the white coating has good reflective performance, and coating the outer surface of API 650 floating-roof tanks with white coating can reduce the evaporation consumption of the oil tank.

Service concept: first time to understand customer needs, first time to solve customer worriesVision: to be the leading steel materials supplier in the worldWorking principles: Keep promises; Spare no efforts; Be practical and innovative; Pursue excellenceTalent concept: build a team with a dream and complete a dream with a team!Family culture: we rely on the principles of equality, trust, appreciation and family love to form a harmonious and warm family!

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the API 650 floating-roof tanks steel materials can be shipped immediately after passing the quality inspection.

We have a professional after-sales service team, the company has developed a clear service process and service standards, after-sales service team members strictly perform after-sales procedures, comply with service standards. The most important thing is that we have set up the correct concept of after-sales service, "customer first, sincere service for users".
