The name of the API620 design standard is "API620 Design and Construction of Large Low Pressure Storage Tanks", which is a specification for the design and construction of large welded steel and low pressure storage tanks formulated for design. API 620 storage tanks operate at 250F or less with operating pressures exceeding 2 lbs in and less than 15 lbs in .
Steel storage tank construction method:
Ordinary vertical storage tank construction basically adopts the guide chain inversion method: construction preparation material inspection blanking processing inspection tank bottom medium plate welding tank bottom arc edge plate center column and umbrella stand top ring group Welding Hemming Angle Steel Group Welding Temporary Dome Bracket Assembly Guide Chain Lifting Device Dome Group Welding Lower Ring Group Welding Lifting Top Ring Wall Panel Girth Welding Each Ring Girth Seam Group Welding Bottom Ring Corner seam welding of bottom plate edge plate of bottom plate inspection accessory installation vacuum test overall test settlement observation delivery.
The company has long been engaged in the design, construction and on-site installation of foreign API620 storage tanks. It has ASME welding ability certification, API620 storage tanks, API650 storage tank design capabilities, pressure vessel design and manufacturing licenses, petrochemical equipment pipeline general contracting qualifications, and safety Production license, international trade import and export license.
We can supply tanks and vessels required for storage and transportation tanks of various liquids and gases like LPG, PROPANE, PROPYLENE, AMMONIA, LIQUIDCARBONDIOXIDE, CHLORINE , HYDROGEN, NITROGEN, OXYGEN, ARGON, SULPHUR DIOXIDE, BUTADINE, ETHYLENE OXIDE AND OTHER GASES , in a wide range of various capacities for use in domestic, industrial and transportation sectors. The manufacturing of these tanks requires special expertise , technology and strict quality control measures. These tanks are manufactured confirming to various design standards like ASME SECT VIII DIV I & II, AD- MERKBLATTER, PD5500, IS2825 and under the stagewise inspection of various third party inspection agencies like DNV, BVIS, TUV, LLOYDS ,PDIL and others. We also supply a wide range of Process Plant Equipments such as Coded Pressure Vessels, Distillation Columns, Towers, Reactors and Heat Exchangers. Also we undertake turnkey projects to construct Fixed & Floating Roof Tanks, Mounded Storage Tanks and Plant Piping.
Conventional tanks (concrete or mild steel) are prone to aging, wear and corrosion. Concrete can crack when exposed to erosion and natural disasters, leading to water contamination and leakage â?? and usually canâ??t be repaired. MS rusts easily and its also easy heat conductor. FRP â?? Fiber Reinforced Polymer is a strong but light weight glass fiber reinforced plastic composite used in the aerospace, automotive, marine and construction industries. It has a high-strength to weight ratio, an extremely long lifespan, and easy to maintain as well as heat resistant. FRP sectional panel tanks provides all types of advantages which other liquid storage methods doesnâ??t. These tanks are DURABLE, LEAK-FREE, COST-EFFECTIVE OVER LIFECYCLE as well as EASY TO INSTALL, RECONFIGURE AND RELOCATE. This is an ideal option for a wide range of usage including potable water storage, food and factory production, commercial mining, fire protection, industrial liquids, rainwater harvesting, seawater storage, and any other kind of liquid and granular storages.
