API 650 uplifting tanks wall thickness
Upon completion of API 650 uplifting tanks construction, provide Purchase with a Vendor's Certification that the tank conforms to the requirements of API 650 and to the additional requirements as specified.
API 650 uplifting tanks weld tightness test: remove dirt from the API 650 uplifting tanks weld, apply white powder emulsion, spray kerosene on the other side of the weld after drying. Because of the strong penetration of kerosene, if kerosene is sprayed after 12 hours (under low temperature conditions, the time can be extended), if the surface of the welded seam coated with white emulsion has no spots, the welded seam meets the requirements.
In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API 650 uplifting tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.
The company has a mature technical team whose reponsibility is to design the drawing, choose suitable material and evaluate the whole production processaccording to customers’ requirement. The company is led by talents and technology, and comprehensively promotes its six business segments like steel material supply, precision steel casting, environmental protection equipment, household appliance, API 650 uplifting tanks steel structures and oil tank projects.
