Allied Equipment

We produce top quality allied equipments for gas plants. Our spares parts are precisely designed to suit varied compressors and give excellent performance for longer duration. The compressors and allied equipments offered by us are manufactured using top quality raw material and advanced technology

Oxygen Plant

Oxygen Plant

The SANGHI-ORG Oxygen Plant, is safe and economical to operate. It comes with an efficient expansion engine, which lowers the operating pressures remarkably to as low as 32-35 kg/cm2 and also cuts down power consumption.

A Molecular sieve Battery drier unit for separation of moisture and carbon dioxide is another money-saving device in the SANGHI-ORG plant. It removes acetylene and other hydro-carbons from the process air, thus eliminating the need for separate acetylene absorbers, and moreover it eliminates recurring caustic soda costs.

The SANGHI-ORG Oxygen Plant is capable of simultaneously producing high purity Oxygen Gas and Nitrogen Gas. It also has an internal compression Liquid Oxygen Pump to fill dry gaseous oxygen in cylinders.

We also undertake supervision of Installation and Commissioning of the SANGHI-ORG Oxygen Plant.


Expansion Engine

Expansion Engine
The Expansion Engine is a vertical single acting reciprocating type engine.

The Electric Motor is used initially to start the machine. Thereafter the engine is moved by the air pressure itself and during which time, the engine motor retains the speed by acting as a brake. Since work is done by air in rotating the Flywheel, it loses its heat content (enthalpy). Thus the air gets cooled. This cooling is more than that of an expansion in an expansion valve. The Expansion Engine can be considered as three major units:

  • Drive unit.
  • Cylinder Unit for air expansion
  • Hydraulic Systems for operating the Valves.

The High Pressure Expansion Engine is used for liquid Plants.

O2 Plant
We are leading manufacturer of oxygen gas plant used in Furnace in Steel Industry from 40 cu.m to 600 cu.m/hr. The purity of oxygen is 99.5% minimum and can be increase upto 99,75.

Liquid Oxygen Pump

Liquid Oxygen Pump
The Liquid Oxygen Pump is a single acting piston pump. It is used for filling Oxygen into Cylinders upto a pressure of 165 kgs./cm2. The pump is designed for assembly in air separation unit that works by pumping liquid Oxygen and gasifying the same in Heat Exchangers for final filling as gas in Cylinders. Control of liquid feed is not necessary, because the pump is designed in accordance with the plant size and the liquid produced is constantly pumped off. The drive unit is similar to any reciprocating machine with the Crank Shaft, Flywheel, Connecting Rod, Cross Head, etc.

The Liquid Oxygen Pump consists of a stainless steel inside liner with liquid inlet and evaporated gas outlet ports. There are no valves on these ports, which are closed by the piston itself on the pressure stroke. The third outlet is the main discharge outlet with the two non-return ball valves. The two ball valves remain firmly closed during suction stroke, due to high pressure in partly filled cylinders. To ensure that these valves are fully closed, a positive pressure of about 60 kgs/cms2 must be maintained on it. When a fresh batch of cylinders is taken for filling, open the manifold valve slowly or use a spare batch of cylinders to ensure positive pressure on these valves.

Gas Ancillaries

Gas Ancillaries
Besides manufacture and export of Oxygen / Nitrogen plants, Acetylene Plants and Nitrous Oxide plants, we can also supply you with the following ancillaries. Tailor made items can be offered to suit specific requirements.

Sanghi-Molecular Sieve Battery:

To remove moisture, Carbon-di-oxide & traces of Acetylene and other hydrocarbons consisting of 2 dries filled with molecular sieve along with regenating electric heater. Temperature sensors & control panel with temperature controller. Each vessel of Molecular Battery is filled with molecular sieve of 1.5/3 mm type 13-X. This is regenerative type capacity 400m3/hr to 2000 m3/hr and 12 hour regeneration cycle.

Sanghi-Purifying mass & L K Mixture:

A mixture of purifying mass & L K Mixture is used to remove unpurities such as Sulphur, Phosphorus, Arsenic, Ammonia etc. in the form of hydrides such as Hydrogen sulphide, Phosphine etc. This chemical is regnerative, can be used for several applications.

Sanghi-Distribution Panel For Oxygen / Nitrogen Plants:

This is a free standing, non-compartmentalised Structure housing the starter feeders for all the drives required for the Acetylene Plant / Oxygen plant and is fabricated out of CRCA steel & is surface treated to international quality standards. It has a front opening and has adequate cabling space. The panel is dust-proofed using double-lipped Neoprene rubber gaskets. The door hinges are concealed and have a back-up channel to ensure proper dust-proofing. The wiring is done with black PVC insulated stranded Copper wires & the wire terminations are identified with PVC ferrules.

Sanghi-Water Pump:

The centrifugal Monoblock pump is of close grained cast iron construction. A statically balanced impeller is fitted to give maximum output at low running cost. RPM 2880; 3.0 H.P.; Power Supply 3Ph; 50 cys; 400 / 440 Volt; A.C. Supply capacity.

Sanghi-Weighing Scale:

Dial Scale 3205 CLE / COE Capacities: - 100, 200, 300, 500 & 1000 Kg. White pointer with black indicator to give shadowless line-to-line (non-parallax) indication on 584 mm dia. Ready line . Scale mounted on four wheels enclosed in a substantial cast iron frame. Tough, dust proof and moisture proof housing to stand up to any conditions. This ensures no rusting and no deterioration of the mechanism components.
