Features of Vertical Series Bulk Storge Tank:
1.Inner Vessel: Austenite stainless steel material for cryogenic application with optimized design.
2.Outer Vessel: High-quality carbon steel outer with a combined leg and lifting lug system designed for safe transport, easy lifting and low cost installation.
3.Insulation: Specific inner structure design, a proven high quality pumping system and perfect detect device ensure good performance and long term vacuum performance , backed by a 3 years warranty on vacuum integrity
4.System of Valve and Pipe: Compact design of modular structure, pipe system of WOLVERINE.
Compact structure, the pipe is shorter than 2/3 length of normal tank, maximum reduce the heat loss of outer pipe.
A combination valve to reduce welded joints, lower cost and maintenance cost.
Design pipe flow, valve and instrumentation to be in good position through ergonomic.
Pipe system of full stainless steel is the reliability of long running
Other valves, such as valve of stainless steel and threaded connection can be manufactured according to clientsí» requirements.
Inner pipe design is calculated and checked by using related engineering procedures in USA, ensure the quality of product.
5.Pressure Adjust: An easily adjustable multifunction combination regulator, equipped with an aluminum auto-boosting dewar and booster of other types, including booster of high-out or lining stainless steel pipe, can be selected by customersí» requirements.
6.Instrumentation: High quality pressure gauge and differential pressure level gauge are standard with optional pressure/level indicator with remote transmission.
7.Safety: Tanks are equipped with dual relief valves with a variety of options, including additional relief valves and/or rupture discs. Easily accessible valves and safety relief valve outlets directed away from the operating area.
8.GB-150 Standard: Tanks are designed and manufactured according to China National Standard Pressure Vessels GB-150 and GB-18442.
9.Cryogenic Liquid Pump: When tank is output by using cryogenic liquid pump, it can use siphon pipe remodeling designú¼to make the pump in good working conditions.
10.Cleanliness: All tanks and their components are cleaned in accordance with requirements of liquid oxygen.
11.Outer Finish Surface Pretreatment : High grade of sandblasting and rust-removing, painting with standard durable corrosion resistant epoxy-polyurethane white paint.
12.Transport: Special rugged internal supports for safe transportation by road, rail or sea.
