API 650 flexible liquid storage tanks workmanship

API 620 Crude Oil Tank Pneumatic Pressure
An air pressure equal to 1.25 times the pressure for which the vapor space is designed shall be applied to the enclosed space above the water level. In the case of a double-wall tank with an open-top inner tank, where the air pressure acts against the outer tank and the inner tank is thus not stressed by the air pressure, the inner API 650 flexible liquid storage tanks may be emptied of water before the pneumatic pressure test begins. The test pressure shall be held for 1 hour.The API 650 flexible liquid storage tanks external floating roof tank of API 650 tank has many advantages, and its application range is more and more wide. It is a kind of storage tank with a bright future. The well-designed internal floating roof tank of API 650 tank is the best and least investment method to control evaporation loss of API 650 flexible liquid storage tanks Fixed roof tankIn 2016 Our company offer 1200 tons API 5L GRB hot rolled coil to Bangladesh——100 tons for 39*625mm, and 1100 tons for 7*683mm It is one tender project, we get the tender at the end of 2015, and arrange the production in 2016 They required the tolerance of thickness is +01/-02mm, and width tolerance is +/-05mm, which is a very high requirement for coil tolerance, but our mill handling this very well and our Q/C department witness all of the process,API 650 flexible liquid storage tanks., Oil tanks can be divided into above ground storage tanks, underground storage tanks, offshore tanks and submarine tanks according to their installation positions. Oil tanks can be divided into crude oil tanks, fuel oil tanks, lubricating oil tanks, edible oil tanks, etc.. According to the use of oil tanks, oil tanks can be divided into production tanks, storage tanks, etc.. According to the external style, oil tanks can be divided into vertical tanks, horizontal tanks, etc.. According to the composition structure, oil tanks can be divided into fixed roof storage tank, floating roof tank, spherical tank, etc.Through the operation and management, brand advantage and improve pre-sales, sale of after-sales service, the efforts of the company into the industry leading enterprises.Relying on perfect quality management system, it has built up competition predominance and provided high quality, favorable price and perfect after service for customers.
