API standard 650 open top welded storage tanks lateral loads on columns
API 650 is the standard for welded tanks for oil storage. It specifies the design, manufacturing, welding, inspection and installation requirements of oil tanks. API 650 API standard 650 open top welded storage tanks is widely used in storage tanks with internal pressure less than or equal to 2.5 PSI, used to store products such as crude oil, gasoline, chemicals, and produced water. BBN has extensive experience in API standard 650 open top welded storage tanks API 650 tanks with diameters between 8'-300', suitable for refineries, terminals, pipeline facilities and other customers.
The elastic filling and sealing of floating roof API standard 650 open top welded storage tanks is to fill the elastic and changeable objects in the sealed envelope, and the sealing purpose depends on the compression deformation of the filler. This kind of sealing effect is good, the requirement of the geometry of tank wall is not too high, and the adaptability is strong. However, the elastic filling and sealing has poor wear resistance and is easy to deform and damage in long-term use.
The ring of API standard 650 open top welded storage tanks annular plates shall have a circular outside circumference, but may have a regular polygonal shape inside the tank shell with the number of sides equal to the number of annular plates. These pieces shall be butt-welded in accordance with API Standard 620 R.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by welds as required by API Standard 620 5.9.5 except when a full penetration weld is used or required.
Considering the large workload of allocation and transportion for our steel materials, we have built special shipping department, and make it independent form transportation department. The transportation department is in charge of transporting steel materials from our mill and warehouse to the port, and our shipping department is in charge of the shipping matters. So that our whole shipping efficiency is improved, and shorten time for customers to receive goods.
The company's logistics and transportation department is responsible for developing high-quality third-party logistics companies, to coordinate and follow up the situation of steel materials transportation. Third-party logistics companies provide us with professional logistics services. With this logistics management method, the time for delivery of steel materials is faster, and the logistics service is professional, multifunctional and comprehensive.
