API 650 stainless and carbon steel tank bottom-reinforcing plate

The API 650 is widely used for tanks designed to withstand low internal pressures, for the API 650 stainless and carbon steel tank 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.

Inspection of API 650 stainless and carbon steel tank bottom: magnetic flux leakage scanning technology is used to detect the corrosion condition of API 650 stainless and carbon steel tank bottom plate (such as corrosion depth and area, crack length, etc.). When there is a defect in the bottom plate of the API 650 stainless and carbon steel tank, the magnetic field distribution will change and the sensor can detect it. The bottom of the oil tank should be free of foreign matters and dry during testing. Weld inspection of API 650 stainless and carbon steel tank bottom plate: when vacuum leak test method is used to detect the tightness of oil tank bottom plate, soap water shall be applied to the weld and vacuum box shall be covered for observation.

API 650 stainless and carbon steel tank Pressure-relieving DevicesTanks shall be protected by automatic pressure-relieving devices that will prevent the pressure at the top of the tank from rising more than 10% above the maximum positive gauge pressure except as provided in API 620 standard 9.2.2.Where an additional hazard can be created by the exposure of the tank to accidental fire or another unexpected source of heat external to the tank, supplemental pressure-relieving devices shall be installed. These devices shall be capable of preventing the pressure from rising more than 20% above the maximum positive gauge pressure. A single pressure-relieving valve may be used if it satisfies the requirements of this paragraph and 9.2.1.

Every customer who has visit us and witness the steel materials before delievry will be impressed by our quality control departemnt. Even not come to inspect the steel materials before delievry, our quality control departemnt will also send inspection report to the customer. For each order, no matter its quantity and value, our quality control departemnt will make strict inspection before delivery, the inspection contents include apperance, tolerance, dimension, mark, special requirements of customers, etc. To guarantee our steel materials sent to the customer is qualified.

The mode of iron and API 650 stainless and carbon steel tank steel logistics transportation is mainly intercontinental ocean shipping and inland rail transportation. European ports have been very mature after years of development, such as Hamburg in Germany, Rotterdam in the Netherlands and Antwerp in Belgium. Relying on the huge market of the European Union, these ports are positioned in the logistics distribution function of cargo distribution and large import and export, and play a great role in the transportation of API 650 stainless and carbon steel tank steel logistics.
