Petro Energy Man (PEM) – Heat Exchangers Manufacturers
Petro Energy Man Group (PEM) began its operations in 1975. In its early years, the company primarily focused on executing civil projects and providing related technical services — a path that laid the foundation for PetroMan’s strong and successful presence in the nation’s construction sector.
Strategic Development and Entry into Power Plant Industries
A major turning point in PEM’s growth came in 1976 with its entry into power plant projects. This milestone was achieved through strategic collaborations and the acquisition of technical expertise from international partners such as Brown Boveri and Asseck.
Through a deliberate strategy of targeted specialization, PetroMan systematically expanded its scope of operations over the following decades. By the mid-1990s, the company had successfully evolved beyond civil construction and established itself as a comprehensive EPC (Engineering, Procurement, and Construction) contractor, actively operating in key sectors including oil, gas, petrochemical, power generation, and cement industries.
Standardization and Current Capabilities
Today, Petro Energy Man stands as a capable and certified contractor, officially recognized by the Planning and Budget Organization of Iran. This formal accreditation serves as a testament to the company’s high capacity and technical expertise in delivering large-scale industrial megaprojects across the country’s infrastructure sectors.
By maintaining strict adherence to international quality standards, PetroMan has earned the lasting trust of a wide range of prominent domestic and international clients.
Strategic Network and Sustainable Competitive Advantage
Petro Energy Man plays a role that extends far beyond that of a traditional EPC contractor.

How PEM Meets Customer-Specific Requirements
In general, the following stages are carried out at PEM, from design to execution, in the fabrication of a heat exchanger.
Data Collection for Equipment Design
In this stage, all necessary design information is gathered, which can be extracted from the process datasheets provided by the client. The collected data include:
- Specifications of the hot and cold fluids
- Operating temperatures and pressures for both hot and cold sides
- Thermodynamic properties of the fluids, including density, viscosity, and heat transfer coefficients
- Fouling factors for both hot and cold fluids
- Allowable pressure drops and flow velocities on the shell and tube sides, which must be considered during the design process
Process Simulation
At this stage, heat exchanger simulation is carried out, marking the beginning of the design phase. In addition to the thermal design, which determines the required heat transfer area and heat duty, a hydraulic simulation is also performed.
Using the constraints of fluid velocity and pressure drop for both the hot and cold sides, parameters such as tube length, inner diameter, and outlet temperatures of the fluids are calculated to achieve optimal performance and efficiency.
Mechanical Design
At this stage, based on the data obtained from the previous phase and in accordance with ASME Section VIII and TEMA (Tubular Exchanger Manufacturers Association) standards, key parameters within the heat exchanger design—such as shell thickness, tube thickness, flange and gasket dimensions, bolts and nuts, and other components—are calculated. Finally, the total equipment weight is determined.
Thorough knowledge and understanding of these design standards play a crucial role in achieving an optimized and reliable mechanical design.

High Pressure Heat Exchanger Manufacturer
A high-pressure heat exchanger is a specialized equipment designed to operate under conditions where fluids flow at very high pressures. These types of exchangers play a critical role in industries where high-pressure boilers are an integral part of production or operational systems. The primary function of these units is to transfer heat between fluids at different temperatures safely and separately, ensuring no mixing occurs and maintaining stable performance under high pressure.
Designing and manufacturing high-pressure heat exchangers requires advanced technical expertise and the use of high-quality materials to withstand mechanical forces from internal and external pressures, while ensuring long-term stability and safety of the boilers.
Given the critical importance and design complexity of these units, selecting a reputable manufacturer for high-pressure heat exchangers is essential. In the following section, we outline the key factors to consider when choosing a reliable manufacturer for such equipment.
Key Factors in Choosing a High-Pressure Heat Exchanger Manufacturer
Selecting a manufacturer for high-pressure heat exchangers is a critical decision that directly impacts the efficiency, safety, and long-term operational costs of a project. Issues such as leak in shell and tube heat exchanger—which often result from poor design, inadequate material selection, or substandard fabrication—highlight the importance of choosing a qualified and experienced manufacturer with strong expertise and experience, reliable design and engineering capabilities, compliance with standards and certifications, advanced testing and inspection facilities, and the ability to deliver custom manufacturing solutions. To make the best choice, several key factors should be considered.
Compliance with Standards and Certifications
A reputable manufacturer should produce equipment in accordance with international standards for high-pressure systems. Standards such as ASME BPVC Section VIII for pressure vessel design and construction, TEMA for shell and tube heat exchangers, and API 660 for industrial heat exchangers in the oil and gas sector are among the most important. Obtaining recognized certifications demonstrates the manufacturer’s commitment to quality and safety.
Design and Engineering Capabilities
A leading manufacturer must have strong design and engineering capabilities. This includes using specialized heat exchanger design software such as HTRI and Aspen EDR to accurately simulate flow, temperature distribution, and pressure drop. These capabilities help optimize dimensions, reduce pressure losses, and enhance the thermal efficiency of the heat exchanger.
Testing and Inspection Facilities
The manufacturer should have adequate facilities to perform thorough post-production testing. These tests include hydrostatic pressure testing, leak tests, thermal performance testing, and non-destructive inspections (NDT) such as UT, RT, or PT to ensure the integrity of welds and the internal structure of the heat exchanger.
Custom Manufacturing Capability
Given the diverse needs of various industries, a manufacturer’s ability to design and fabricate custom heat exchangers based on specific technical requirements is a significant competitive advantage. This capability ensures that the heat exchanger aligns optimally with the operational system.
Expertise and Experience
Manufacturers with extensive experience in designing and producing high-pressure heat exchangers possess the knowledge and technical skills necessary to address complex engineering challenges. Their ability to provide specialized consultation and deliver customized designs for specific operational conditions is crucial. Companies with a proven track record of successful high-pressure heat exchanger projects in similar industries are generally more reliable and reputable.
