API Std 650 unanchored tanks weld hardness
Impact Requirements for Controlled-rolled or Thermo-mechanical Control Process (TMCP) Plates: Subject to the approval of the Purchaser, controlled-rolled or TMCP plates (material produced by a mechanical- thermal rolling process designed to enhance the notch toughness) may be used where normalized plates are required. API 620 welded storage tanks each used plate, as rolled, shall be Charpy V-notch tested to the requirements of R.2.1.2.
All edges of the inner wall of the API 650 petroleum storage tank to be lined or coated must be rounded and flat to a minimum radius of 3mm. The API Std 650 unanchored tanks internal welding seam must be completely sealed welding, with a smooth surface and no air holes, air pockets and local protrusions. Remove welding spatter. As specified in API 650 petroleum storage tank design drawings, the seller must perform additional surface treatment.
FANALCA is the biggest motorcycle factory in Columbia. Meanwhile, it is the only distributor in Colombia for Japanese Honda. We began to cooperate with each other since 2017. We supply SAPH370, SAPH440 and so on automobile steel coils to them. As our products quality is proved to be satisfied during their production, they have been one of our stable customers, and give repeat orders about automobile steel every year.
}Atmospheric API Std 650 unanchored tanks refer to storage tanks whose gas or vapor pressure is greater than -0.02MPa but less than 0.1MPa. Metal atmospheric storage tanks made of steel welded on the ground are often used to store petroleum, chemical and other similar liquids. Atmospheric API Std 650 unanchored tanks usually have a connecting pipe directly connected to the atmosphere, so that the operating pressure in the storage tank does not exceed the design pressure at all times.
We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
