Construction of Conical bottom of API620 storage tank

The Conical bottom of API620 storage tank 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.

The results of adopting two-level Conical bottom of API620 storage tank service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and Conical bottom of API620 storage tank after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

The API 650 is widely used for tanks designed to withstand low internal pressures, for the Conical bottom of API620 storage tank storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.

Our vasion is to create a first-class steel plate manufacturing enterprise with international competitiveness. Business Vision: Improve value with quality and become the leader in the industry. Core values: people-oriented, integrity, responsibility, excellence. Development strategy: Seek development through science and technology, and seek benefits from management. Besides, we will create a harmonious business atmosphere, unblock the channels for employees to communicate, and build a stage for various sports and talents.
