The demand for and use of products obtained from the Petrochemicals sector is enormous. The worldwide petrochemicals market is anticipated to reach $958.8 billion by 2025, with a CAGR of 4.6% from 2020 to 2025. Industry studies Petrochemicals are components obtained from oil and gas that are used in a wide range of everyday items, including plastics, fertilizers, packaging, textiles, digital gadgets, medical equipment, detergents, and tires. The petrochemical industry is characterized by exposure to the risks of high temperature, high pressure, flammability, and explosion. Any sudden loss of power to the control instruments of important equipment may lead to personnel injury, serious environmental pollution, and massive economic losses. This is why the petrochemical industry has a huge demand for UPS products and high requirements for product quality. They are intended to keep manufacturing running smoothly by controlling the flow of liquids or gases used, whether in safe or potentially hazardous environments. Businesses may ensure that they are being as efficient as possible by keeping production processes working at their peak. Being able to monitor and control temperature, pressure, flow and level are essential within the petrochemical industry for safety and product integrity. Each category has its own subcategories, so we have designed a range of products, all built with integrity, reliability, and quality, to meet the differing needs of this industry.
Products and Solutions
UNINTERRUPTIBLE POWER SUPPLY (UPS SYSTEMS)
Using a contemporary IGBT rectifier greatly lowers disturbances in the power source. The novel IGBT rectifier offers nearly sinusoidal current usage. Because of the increased performance factor at the rectifier’s input, UPS systems of this type have up to 30% lower input performance when compared to typical UPS systems with a Thyristor rectifier. When dimensioning the spread of fuses and cables on-site, the decrease of power at the rectifier’s input during grid feed allows for significant savings.

HIGH PRESSURE THERMOCOUPLES
There are many considerations which must be considered, when designing thermocouples for high pressure service. The designer must be familiar with the effects of corrosion, environment, creep, fatigue, and thermal and mechanical stress.
Corrosion
The designer must be aware of the possibility of corrosive conditions to make intelligent material choices. Material choices must be compatible with the process media over the entire operating temperature range of the device. This consideration is important to prevent production losses due to a premature failure of the high-pressure devices.
Embrittlement
Embrittlement occurs when metals exceed rated temperature or combine chemically with certain gases or other compounds. TCP engineers, in cooperation with the customer, carefully select the proper alloys to minimize or eliminate this problem.
Creep
This condition is caused by high pressure and temperature. Careful attention is given to the possibility of metal deformation to hold it within prescribed limits. The design limits are particularly important when designing the sealing areas in high pressure service. Poor seals result in leaks with their associated safety record of their high-pressure devices and thermocouple probes.
Fatigue
Vibration, flexing, twisting etc. all are causes of fatigue failure. Fatigue failure is another problem our designers minimize by carefully questioning the customer and becoming familiar with the application. In this area, overdesign can be as harmful as under design in obtaining useful.
service life with maximum safety. Our design engineers have many years of successful experience in this important area.
Mechanical Stress
Like thermal stress except mechanical stress failure is due to high pressures. Symptoms include bulges and ruptures. Successful design of devices to handle mechanical stress in addition to all the other conditions listed above is what sets TCP apart from the usual thermocouple supplier.
