A334 grade 1 pipe cylindrical steel welding oil tank

A334 grade 1 pipe cylindrical steel welding oil tank

A334 grade 1 pipe cylindrical steel welding oil tank

The thickness of the cylindrical steel welding oil tank annular bottom plates shall be in accordance with Table Q-4 (for steel or aluminum, as applicable). The thicknesses shown are minimums. The ring of annual plates shall have a circular outside circumference, but it 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 Q.7.1.1, Item b. The plates of the first shell course shall be attached to the annular bottom plates by a weld as required by API 620 oil tank 5.9.5 except when a full-penetration weld is used or required (see Q.7.1.1). Butt-welds in annular plates shall be not closer than 12 in. from any vertical weld.

Before the start of erection, inspect each API 650 tank foundation to ensure that it is level and acceptable to receive Work. Remove temporary erection attachments welded to the interior or exterior of the cylindrical steel welding oil tank shell or to the bottom by arc gouging, and grind weld area smooth.

After the order is finished, our after-sales service center will send an email to make a feedback about our steel products' quality. We have phone service every three months to remind our customers of the possible problems and collect advices or suggestions in quality and service. Upon the collection of advices or suggestions, our after-sales service will quickly make technical solutions to wipe out the customer problem.

Generally, the building area temperature of the cylindrical steel welding oil tank should be considered before the tank design and construction. The temperature in the cylindrical steel welding oil tank building area is closely related to the evaporation loss, energy loss, storage tank materials and the selection of detection instruments, or has a direct impact on the storage cost of the storage liquid. For the same medium, the higher the air temperature and the longer the duration, the higher the material temperature in the cylindrical steel welding oil tank, the higher the corresponding pressure and the more volatile loss.
