Shell heat exchanger tube / two-tube

Heat exchangers are being considered as the most important equipment in oil and gas facilities industries. One of particular usage of heat exchangers is recycling heat loss in chemical process which is done by heating between the fluids through the tube and shell to increase or decrease the fluid temperature in corrosive environments. It should be noted that in severe corrosive environments, there is possibility of anti-corrosion coating metal (Cladding) according to customer's order.

 Air coolers  

Air coolers are one of the most important equipment in the refining, petrochemical and gas stations which are used by blowing air over the fins of the tubes and reduces heat of fluid inside the pipe. The fluid may be natural gas, liquids, oil and water. In terms of technology header of air coolers have very high sensitivity and in a state of Induced / Forced Draft so designed and produced according to the standards of API-661, ASME, TEMA
Some facilities of air coolers include: automatic change of Louver for outlet temperature control, thermal Coil system to prevent freezing fluid in cold weather, control system automatically change the angle of the fan, motor speed control system to obtain good thermal efficiency and control valves

Spherical tanks

Spherical tanks are manufactured for the first time in the country by Machine Sazi Arak. Constructing about 90 spherical tanks in Iran and other countries are the glories of Machine Sazi Arak. All mechanical and structural design, purchase of raw materials, forming sheets, cutting, assembly and installation is done by the company. Spherical tanks are using for storage of petroleum refineries and petrochemical industries at high volume and pressure.
Engineering standards to design, construction and installation are: AD-MERKBLATT, ASME SEC & DIV I, ASME SEC & CIV II & PD 5500
The first spherical tank in Iran designed and constructed by Machine Sazi Arak for Petrochemical Complex of Isfahan.

Construction and installation of spherical tanks for the followings making us proud:

Bandar Abbas Refinery, Imam Petrochemical MTBE Project, Tabriz Petrochemical, Arak Petrochemical, Amir Kabir Petrochemical, Bu Ali Petrochemical, Turkmen Kianly Port, Persian Gulf Refinery, Tehran Refinery

Gas stations

Natural gas in mail pipeline of gas have high pressure which may not be suitable for use in home and industrial usage. Gas stations reduce the gas pressure in main lines and adjust it according to the distribution lines pressure. Other operations, such as measuring the flow of gas stations, heating, filter and odor of gas can be performed.


In order to isolate suspended particles and heavy liquid from gas, using centrifugal force and passes the fluid on a large number of filters a device called a scrubber is used in oil and gas transmission stations. This device is composed of a large number Cyclone which is as filters charged. Scrubber features are lack of resistance in passing line, constant pressure regardless of the contamination and operating on a wide range of flow changes.

Filter separator

Filter separator are used to treat gas in refineries, units exploitation of oil and gas wells. The device is able to separate 99.9% of liquid and solid particles up to 2 microns from gas. It rapidly deployable door mechanism for ease of replacement filters.

Dry gas filters

Gas filters are placed in gas pipeline for separating solid particles up to 5 microns. Gas  flow after entering the filter will be slowed, the larger particles suspended in a gas chamber, and the smaller particles is isolated by facing to filter element so clean gas via outlet pipe leaves the chamber filter.

Indirect gas heaters

Indirect gas heaters are widely used in manufacturing, processing and distribution of oil and gas. The most important use of indirect gas heaters is heat transfer to the high-pressure gas flow.

Launcher and receiver

Launcher and receiver unit by transmitting pig in oil and gas pipelines and pressure from the loading path, collect the sediments from pipeline internal walls at the end of the pipeline and direct to receiver with flushing of the inner pipe, by a thickness gauge on the back of pig, internal surface in terms of corrosion and thinning will be checked.

Direct gas heaters (amplifier filter)

These heaters will be used to increase the temperature by direct flame in the oil, gas and upstream industries. All operations such as design, construction and installation of direct heaters is done by Machine Sazi Arak.

Storage tanks

Engineering, construction and installation of a large number of storage tanks with fixed conical and domed roofs, floating roof and double-walled storage tanks, and construction and installation of the Middle East largest floating-roof tanks with a capacity of 1.333 million barrels at Isfahan refinery are considered as company's brilliant experiences.
