API 650 aluminum tanks double-welded lap joint
The API 650 tank Standard has the built in flexibility to be used in building tanks to store a wide variety of products while ensuring the structural stability of the API 650 aluminum tanks tank.
Requirements for prefabrication of bottom plate of large vertical API 650 aluminum tanks:1. The diameter of tank bottom should be enlarged by 0.1% ~ 0.15% according to the design diameter.2. The minimum dimension of edge plate along the radius direction of tank bottom shall not be less than 700mm.3. The distance between any adjacent welds of the base plate shall not be less than 300 mm.
Standard Hydrostatic and Pneumatic TestsAfter erection is completed and stress relieving, radiographic examinations, or other similar operations, as may be required, are performed, each tank shall satisfactorily pass a series of hydrostatic and pneumatic tests as prescribed in 7.18.2 through 7.18.6. Whenever a solution film is specified in this section to be applied to welding, linseed oil or another equivalent material for disclosing air leakage may be substituted. In freezing weather, linseed oil or a similarly suitable material shall be used.The attachment welding around all openings and their reinforcements in the walls of the API 620 tank shall be examined by the magnetic-particle method both inside and outside the tank API 650 aluminum tanks. When the underside of a tank bottom rests directly on the tank grade (and is not accessible after erection), such examination of welding on the underside of the bottom and subsequent air testing may be omitted.
Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
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 aluminum tanks steel materials can be shipped immediately after passing the quality inspection.
