5154 aluminum tube API Std 650 ambient temperature tanks

The company has been engaged in the design, construction and installation of foreign API 650 standard API Std 650 ambient temperature tanks storage tanks for a long time. It has the international qualification of ASME welding technology, has the design ability of API 650 oil tanks and API 650 storage tanks, and has pressure vessel design and manufacturing license and GC pressure pipeline installation license. Certificate, API Std 650 ambient temperature tanks petrochemical equipment pipeline general contracting qualification, safety production license, international trade import and export license.

Soil Structure Interaction: Soil structure interaction per API 650, Section E.6.1.6 may be used for OLE design providing the damping ratio does not exceed 10 %.
Allowable Stresses
Design allowable stresses shall be per API 620 large welded steel storage tank, Section Q.3.3, including the 33 % increase permitted for earthquake loads.
Self-anchored Inner Tank
The anchorage ratio for a self-anchored inner tank, J, shall not exceed 1.0 for the OLE design combination to limit uplift and stresses in the annular plate and corner weld.
Foundation Stability
The overturning ratio defined in API 650, Section E.6.2.3, Equation (E.6.2.3-1) shall be equal to or greater than 3.0 for the defined OLE event.

The main reason of "small breathing" loss of API Std 650 ambient temperature tanks is the change of atmospheric temperature. When the temperature rises with the increase of solar radiation from dawn, the temperature of oil in the API Std 650 ambient temperature tanks also changes, resulting in the acceleration of evaporation speed and the increase of evaporation pressure. When the pressure exceeds the positive pressure rating of the breathing valve, the oil-gas mixture in the API Std 650 ambient temperature tanks is discharged into the atmosphere through the breathing valve, which is the "exhalation" process of the oil tank.

Based on the principle of “sincerity and win-win cooperation”, our company keeps forging ahead. In the fierce market competition, we have won the trust and rapid development of our customers with good cooperation and sincere service spirit. With pioneering spirit, the pursuit of excellence, continuous learning, and never satisfied content, we will create a win-win situation with our customers to create a better future. The company has sufficient inventory and complete varieties and specifications.

Tianjin warehouse mainly stores steel plates and steel pipes. The monthly replenishment is about 12000 tons. Our inventory cycle is short and flexible. Shanghai warehouse mainly stores API Std 650 ambient temperature tanks ,steel plate and section steel. The average monthly purchase volume is about 15000 tons. The geographical location of the warehouse has greatly improved our performance in terms of transportation and delivery time.

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.
