API 650 insulated tanks guide pole

In this project a cylindrical tank 75 ft in diameter is designed for an internal pressure of 0.5 lbf/in.2 gauge in the vapor space. The plate material is ASTM A131 Grade B steel for thicknesses of 1/2 in. and less.
The top course of the butt-welded cylindrical sidewall is 1/4 in. thick. The tank API 650 insulated tanks roof is a conical shape with a 2:12 slope and a 1/4 in. thickness with single full-fillet welded lap joints. The maximum design liquid level is 6 in. below the plane of juncture of the roof and sidewall.

Supply covers for API 650 insulated tanks connections specified with the service covers remaining in place following tests. For API 650 tank connections not specified to be supplied with service covers, the test covers may be removed after testing.

In the year of 2015, customer from Peru oil refinery contact with us from Internet. After one month’s negotiation and quotation, they chose us as there supplier of raw steel plate API 650 insulated tanks grade ASTM A36. We get an trail order of 300 tons in April. When the first ship arrived, they inspect the steel plate and very happy with the quality we supply. Then they put another 1700 tons order, we sent to them within 90 days. Our company management group visit the customer in the beginning of 2016 and the visit is very successful.

The preparatory work before the construction of the API 650 insulated tanks is an important part of the oil tank project. Material purchase preparation before the construction of the API 650 insulated tanks:
Before API 650 insulated tanks construction, all materials shall be purchased and prepared, and the specifications and quality of materials shall be inspected to see if they meet the construction operation requirements. Fire and rain proof measures should be taken when storing materials. Paint should be stored in a ventilated and dry place.

Due to other non-steel quality reasons caused by the customer dissatisfaction, to timely explain to the customer, and help them solve the problem, for the customer really because of their own reasons, to give patient reply.The process of objection handling is the process of our technical service.
