CSA G40.21 grade 350W plates API 650 mechanically-anchored steel tanks
API 650 petroleum storage tanks are used for API 650 mechanically-anchored steel tanks storage. API 650 petroleum storage tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature). Welding API 650 mechanically-anchored steel tanks certification is regulated by Section 10 of the American Society of Mechanical Engineers (ASME). For API 650 petroleum storage tanks, non-destructive inspections are required, but third-party inspections are not required.
Corrosion of the API 650 mechanically-anchored steel tanks body caused by external conditions such as high temperature, rain, humidity, or inadequate anti-corrosion measures of the oil storage tank itself, the water-bearing deposits in the oil storage tank caused corrosion and perforation of the inner surface of the oil storage tank bottom plate. Defects fatigue cracks caused by stress, with the accumulation of time, the compressive strength of the API 650 mechanically-anchored steel tanks body decreases and corrosion cracks occur.
Material for the outer tank API 650 mechanically-anchored steel tanks and for the roof that contains the vaporized liquefied gas but is primarily subjected to atmospheric temperatures may conform to one of the following:a)Table 4-1 for design metal temperatures down to –35°F (lowest 1-day mean ambient temperature of–35°F) without impact test unless they are required by Table 4-1 or by the Purchaser.b)Table R-3 for design metal temperatures down to –60°F without impact tests unless they are required by Table R-4 or by the Purchaser.
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.
Steel transportation because of the special material of API 650 mechanically-anchored steel tanks steel, is a metal with "iron" as the main basic element, small volume and large weight, and easy to oxidize and rust when contacting with air and rain water, so there are many precautions in the transportation of steel. There are 11 proverbs for steel transportation: "evenly placed, moisture-proof and rust proof". Our company chooses the logistics aspect to be very rigorous, takes the customer's request as the standard, guarantees the steel product quality.
