Tanks are produced to store the inner gas, at -196 ºC or at a less temperature, depending on different design parameters.  The cryogenic storage tanks, pressure vessels, and vaporizers are manufactured in India As a design standard it is used CODE 2000, EN 13458, EN 13530, ADR 2009 and ASME Section VIII Division 1 and CGA-341 codes and standards. It is also possible to design products in different standards according to the requests of customers. 

The cryogenic tank consists of two tanks Outer & Inner Tank. The inner tank is made out of stainless steel  304L (X5 CrNi 18-10) & design code EN13458, While the outer one is made of CARBON STEEL & design code EN13458. The gap between tanks is filled with Perlite aggregation and super insulation by vacuum technology. The manufacturing processes of the tanks are as follows: Tanks are produced to store the inner gas, at -196 ºC or at a less temperature, depending on different design parameters.  LIN, LOX, and LAR cryogenic storage tank capacities range from 300 gallons to 80,000 gallons (50 tons).  Vaporizers are also available in a wide range of capacities - from 700 SCFH (20 Nm3/h) to 35,000 SCFH (1000) Nm3/h per unit.  Also supplies Liquid CO2 storage tanks in sizes holding 3 to 50 tons of products.

Oxyplants India Pvt. Ltd. offers a full line of Dura liquid cylinder. The Dura liquid cylinder is designed to transport, store and deliver oxygen, nitrogen, argon, as a cryogenic liquid or gas. Dura cylinders are vacuum and super  insulated  vertical type liquid cylinders with in-built vaporizer which allows storage of cryogenic gases like oxygen, argon, nitrogen, medical oxygen at a very low temperature ranging From -183deg c To -196 deg c. The Dura Liquid Cylinders are manufactured in India As a design standard it is used CODE DOT4L, EN 13458 and ASME standards. Dura Cylinders are low pressure liquid cylinders provide the longest holding time, lowest evaporation rate, highest gas-withdrawal rate and best life-cycle cost.

Dura Liquid cylinders Tanks are produced to store liquid. The inner tank is made our of Stainless Steel 304L(SA240 TP304) & design code DOT4L. While the outer one is made out of stainless steel 304L (AISI304) & design code CGA-341,Ed.2007 . The common application for this liquid cylinder is to provide gas at pressures around 300 psi (20.7 BAR). The Dura Liquid Cylinder will build and maintain pressure at the control regulator setting of 300 psi (20.7 BAR). If the pressure exceeds 300 psi (20.7 BAR) the control regulator will supply gas from the tank vapor pressure. A continuous gas flow can be automatically provided from these cylinders.

Dura Liquid cylinders capacities range from 40 gallons to 60 gallons.

Oxyplants India Pvt. Ltd. offers a full line of Cryogenic pumps for Oxygen/Nitrogen/Argon Liquid from the cryogenic tank is compressed to high pressure in a cryogenic liquid pump. It is then vaporised in an ambient air vaporiser to produce gaseous oxygen/Nitrogen/Argon. The high-pressure gas then can pass into cylinders via the gas manifold or fed into a customer's product pipeline.

Oxyplants India Pvt. Ltd. supplies Atmospheric vaporizers for Liquid Nitrogen, Liquid Oxygen, and Liquid Argon and of various capacities ranging from 20 to 1000 NM3/ Hr. Ambient Air Vaporizer utilize convection as the heat transfer mechanism.  Ambient air vaporizers use the relative "heat" of the atmosphere to derive the energy necessary for the vaporization of the liquid cryogen. Ambient vaporizers represent the most cost effective equipment to vaporize or re-gasify liquid cryogens. The vaporizers comprise a number of individual multi-finned aluminum heat transfer extruded elements lined with a high pressure retaining stainless steel tube. Extrusions are connected in series. Liners are hydrostatically expanded (tension bonded) into the extrusion element to ensure 100% contact and efficient heat transfer. 

Vaporizers are designed and manufactured in accordance with the ASME Section VIII Div 1 latest edition pressure vessel code and the UBC and applicable sections of ANSI A 58.1. Vaporizers may be manufactured in compliance with any global pressure specification, such as ASME; TüV; PED; and other international codes.

The performance of ambient air vaporizers is subject to many factors. These include flow rate, duty cycle, ambient temperature, relative humidity, freeze period, altitude, wind, solar radiation, operating pressure and proximity to adjacent structures. The effects of average solar and wind conditions are not included in quoted ratings. Performance is based on mean ambient conditions of 70°F (21°C) and 70% relative humidity. Special conditions may vary considerably for a particular application, thereby affecting performance.

Options

  • Special end connections available
  • Electro-polish for semiconductor industry applications
  • Complete piping module assembly packages for vaporizer/piping installations
  • Fog Reduction Module
  • PE Certified Drawings
  • California OSHPD approved designs
  • Tank or trailer mounted designs

 

Benefits and Features

  • Increased ground clearance further enhancing heat transfer by natural convection.
  • High capacity fins measure 8 inches (203 mm) from tip to tip and provide high performance and longevity.
  • Low pressure drop, full-bore passages in the elements provides more flow cross section.
  • Heat transfer elements up to 40 ft (12 m) are available to meet a range of process demands. Standard assembly configurations and ratings are shown on the reverse side.
  • MAWP – 580 psig* (40 bar g) for all aluminum construction.
