ASTM A524 pipe API 650 low-alloy steel tanks

Material for the outer tank API 650 low-alloy 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.

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API 650 low-alloy steel tanks storage of typical products such as crude oil, petrol, chemicals and water. We have extensive experience when it comes to API 650 tanks, varying from tanks built in the factory up to +/- 500m3, to tanks built on-location up to +/-15,000 m3.

On August 29th Clients from Senegal visited us-Zhengzhou office and wanted to know more about BBN to build a long relationship. They have a big demand of ship building steel plates with thickness 6mm and thickness 8mm LR AH36 shipping steel API 650 low-alloy steel tanks plates to Senegal Navy, and our strong advantage in offering these ship building steel plates make us begin to build a steady cooperation relationship with Senegal clients. BBN has always supplied high quality ship plates with stable supply. Soon he placed 15 containers of LR AH36 shipping steel plates to BBN.

The cone slope of the completed API 650 low-alloy steel tanks foundation is 15/1000 for the general foundation and less than 35/1000 for the soft foundation. After the foundation settlement of the storage tank is basically stable, the surface slope must be greater than eight thousandths. The edge of the tank bottom should be more than 0.3 meters higher than the surrounding ground. Above the ground, the tank bottom leakage detection tube should be drawn from the foundation sand cushion and cross the foundation ring wall or the slope protection surface. The circumferential distance should be less than 20 meters, and each API 650 low-alloy steel tanks should have at least 4 detection tubes.

Our company will accept the product quality objection registration record, pass it to the API 650 low-alloy steel tanks production unit and relevant departments, and timely coordinate the supervision of product API 650 low-alloy steel tanks quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
