What is the difference between API 650 & 620?

API 620 regulates the design and manufacture of large steel low-pressure storage tanks, usually larger than 300 feet in diameter. By contrast, API Standard 650 is typically used for carbon, stainless steel and aluminium tanks located in terminals, refineries, pipelines and other process facilities.

What does API 650 mean?

welded tanks
API 650 is the standard governing welded tanks for oil storage. It dictates tank design, fabrication, welding, inspection, and erection requirements. API 650 is widely used for tanks that are designed to internal pressures of 2.5 PSI or less and store products such as crude oil, gasoline, chemicals and produced water.

Another way to perceive this difference is that the ASME standards are the ones to achieve or design towards while the API standards are the recommended practices but that these practices are not legally binding whereas once the pressure system has been ASME certified the ASME certification is legally binding.

What are different API standards?

Discussing different types of APIs, alongside protocols and standards, such as Open APIs, Internal APIs, Partner APIs, Composite APIs, RESTFUL, JSON-RPC, XML-RPC, and SOAP. APIs (application programming interfaces) come in many forms.

Which is design code standards for storage tank?

The API 650 standard covers the minimum requirements for design, manufacture, installation, materials and inspection of aboveground vertical cylindrical tanks, without refrigeration, with open or closed roof, built with welded steel plates.

Is code for storage tank design?

BS EN 14015:2004 is the European design and analysis code for tanks. Its descriptive title is Specification for the design and manufacture of site built, vertical, cylindrical, flat bottomed, above ground, welded, steel tanks for the storage of liquids at ambient temperature and above.

What do you need to know about API 650?

This Standard is meant to be a purchase specification to facilitate the manufacture and procurement of storage tanks for the petroleum industry. If the tanks are purchased in accordance with this Standard, the Purchaser is required to specify certain basic requirements.

When was the first API storage tank published?

2 The First Edition of API 650 was published in 1961, but its predecessor, API 12C, had been in use since 1936, when welding began to replace riveting as the preferred construction method. Both API 12C and API 650 address only newly constructed tanks.
