The API620 internal tank pressures stiffener ring and backing strip (if used) are primary components, and they shall comply with the requirements of API 620 storage steel tank Q.2.1. The stiffener rings may be fabricated from plate using an intermittent weld on alternating sides between the web and the flange.
Except for aluminum or stainless steel tanks, all fillet welds shall consist of a minimum of two passes. The ends of the fillet welds shall be 2 in. from the rat hole (see Figure Q-1), and these welds shall be deposited by starting 2 in. from the rat hole and welding away from the rat hole. An acceptable alternative to the detail that includes stopping fillet welds 2 in. short of the rat hole would be to weld continuously through the rat hole from one side of the stiffener to the opposite side. All craters in fillet welds shall be repaired by back welding.

We have transportation department and shipping department to coordinate logistics and delivery. Seamless connection between inland transportation and sea transportation ensures smooth delivery, saves transportation time and delivers goods in the first time. During the sea transportation, we will update the freight progress for customers on a regular basis, so as to facilitate the tracking of customers and make preparations for receiving goods leisurely and timely.

API 650 storage tanks API620 internal tank pressures are only suitable for containers that can evenly support the entire bottom and containers for non-refrigerated equipment with a design maximum temperature of 200 degrees Fahrenheit. It API620 internal tank pressures requires a minimum thickness of 3/16 inch. Other characteristics of the API 650 storage tank are: it is composed of carbon steel, austenitic duplex stainless steel and aluminum.

Since its establishment, the company has participated in several key railway and highway projects. After years of development, the company’s API620 internal tank pressures domestic market has been exported to more than a dozen provinces and cities including Kunming, Shenzhen, Hunan, Sichuan, Shanghai, Nanjing, Heihe, Jilin, Inner Mongolia, and Xinjiang . International trade is exported to Kazakhstan, South Korea, Vietnam, South Africa and many other countries, and has been well received by customers.
