ISO 630 grade E275 quality D plates API 650 self-anchored tanks
The design metal temperature of API 650 self-anchored tanks each component exposed to the liquid or vapor being stored shall be the lower of the following:a)The minimum temperature to which the tank contents will be refrigerated, including the effect of subcooling at reduced pressure.b)The minimum metal temperature anticipated when the atmospheric temperature is below the refrigerated temperature (see 4.2.1). The effectiveness of the insulation in keeping the metal temperature above the expected minimum atmospheric temperature shall be considered.
API standard 650 is typically used for carbon, stainless steel and aluminium API 650 self-anchored tanks tanks located in terminals, refineries, pipelines and other process facilities. Both have different pressure and temperature parameters as well. Your choice of model will depend on you and/or your client s particular needs.
1200 tons API 5LGRB strips to Bangladesh. In December of 2015, we get one tender project from National Tubes Limited, which is a famous national enterprise in Bangladesh. It is an order of 1200 tons API 5L Gr. B steel strips, they bought these cargo to fabricate ERW pipe in local place.
}When welding API 650 self-anchored tanks, in order to avoid weld deformation, it is necessary to use corresponding welding process according to the type of steel used in the tank, such as welding requirements of steel plate, welding position, etc. Reasonable arrangement of the assembly sequence, the use of subsection back welding and jump welding method, strict control of welding process parameters, rigid fixation measures, take corrective measures for deformation compensation are necessary.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
