ASTM A27 grade 65-35 floating roofs API Std 650 tanks
API Std 650 tanks basic components are those that contain the vaporized liquefied gas from the stored refrigerated liquid but primarily operate at atmospheric temperatures because of insulation system design and natural ambient heating. These components shall comply with the basic rules of this standard. Examples of such components are the outer wall and roofs of double-wall tanks and roof components above an internally insulated suspended deck. The API 620 tank materials requirements are based on the storage of refrigerated products at the design metal temperature.
Similarities between API 650 and API 620 tanks Both tanks are used for storage purposes. Both API 620 and API 650 containers API Std 650 tanks can be made of carbon steel, austenitic stainless steel and nickel alloy (only for low temperature).
Bangladesh is an important market to us. We cooperated with the National Railway, the National Tubes Limited (NTL) and so on state-owned enterprises. They have tenders regularly. And we would participate the tenders with our local agents. We have been the winner of NTL tenders for many times. API 5L grade B steel strips are their needed API Std 650 tanks materials. They have special chemical composition, tolerance and so on requirements. We can fully meet their demands and guarantee timely delivery.
}Strictly control the welding groove forming of API Std 650 tanks: in order to ensure the geometric dimension of assembly and good welding of welding seam, before hoisting and laying, the edge of all metal vertical storage tank plate shall be polished by grinder, and the flatness of plate shall be ensured according to the design requirements. Strictly control the size of API Std 650 tanks weld assembly: measures must be taken to strictly control the assembly size of metal vertical tank bottom plate during assembly.
Our company will accept the product quality objection registration record, pass it to the API Std 650 tanks production unit and relevant departments, and timely coordinate the supervision of product API Std 650 tanks quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
