The LNG oil transportation pressure vessel 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 efficient and quick logistic team service. We promise that after the customer places the order, the spot products will be shipped, processed, and cut on the same day. The steel LNG oil transportation pressure vessel products will be shipped in 2-5 days according to the characteristics of the product. The company has always been adhering to the service concept of "integrity, pragmatism, enthusiasm" and dedicated to providing our customers with high-quality steel products and after-sales service.

When API 650 storage tank is designed, when the design pressure is small F2 kPa, the impact of air pressure on the LNG oil transportation pressure vessel tank wall thickness is not considered in the tank wall design.

It is a modern high-tech professional enterprise integrating scientific research, LNG oil transportation pressure vessel production and sales. The company is mainly engaged in the manufacture, installation and commissioning of boiler and pressure vessel, chemical, metallurgical, petroleum and other equipment, as well as LNG oil transportation pressure vessel process technology development, technology transfer and related technical consulting and technical services.
