Application of Chemical Industry Shaft Forgings in the Petrochemical Field
In the petroleum and chemical industry, where applications involve extreme operating conditions such as high temperature, high pressure, and strong corrosion, chemical industry shaft forgings, with their unique and superior performance, have become core transmission components in this field. They play an irreplaceable role and directly determine whether the equipment can operate stably. Then, from crude oil extraction to refining and processing, what are the specific applications and advantages of shaft forgings in this field? Next, let’s explore.
I. Pump Shafts
In offshore drilling platforms for crude oil extraction and petrochemical production facilities, equipment such as drilling pumps and rotary drilling rigs must continuously withstand high-pressure environments thousands of meters underground, enduring high pressure and high-speed operation. Here, chemical industry shaft forgings act as “stabilizing anchors.” With their high strength, wear resistance, and fatigue resistance, they take on the critical role of transmitting enormous torque, ensuring long-term stable operation of equipment and reducing the risk of downtime.
Take the main shaft of chemical pumps as an example, which is used in equipment such as crude oil transfer pumps, chemical process pumps, and seawater injection pumps, primarily for transporting various liquid media. The shaft bodies we forge using high-strength alloys can not only withstand hundreds of reciprocating impacts per minute but also resist corrosion from corrosive media like hydrogen sulfide in drilling fluids. Moreover, in a refinery where Songjie supplied custom shafts, after purchasing Inconel 718 forging pump shafts, their service life was extended from 6 months to 3 years!
II. Compressor Shafts
Compressors, regarded as the “heart” of the petrochemical industry, are responsible for gas pressurization and transportation. Their main shaft forgings need to withstand high-frequency torque impacts and perfectly match with seals to minimize gas leakage. These chemical industry shaft forgings forgings are widely used in natural gas compressors and air compressors in petrochemical plants, enduring high-speed rotation, enormous torque, and unbalanced forces while maintaining high concentricity to reduce vibration and noise.
Our shafts, through precise heat treatment processes, achieve a balance between high strength and high toughness, enabling compressors to remain “steady as a mountain” even under full load, thus avoiding catastrophic shaft breakage accidents.
III. Reactor Agitator Shafts
During chemical reactions, the interior of a reactor needs to withstand complex changes in pressure and temperature. Chemical shaft forgings can ensure the structural strength of the equipment, guarantee uniform and efficient reaction processes, prevent accidents, and ensure production safety.
Taking the agitator shaft of a reactor as an example, it is applied in stirring equipment such as reaction kettles and mixing tanks. It is mainly responsible for the uniform mixing of materials in the reaction kettle, can effectively resist chemical corrosion, and prolong the service life of the equipment.
IV. Turbine Shafts
In the petrochemical field, turbine shafts, as key chemical industry shaft forgings for power transmission, are used in steam turbines and gas turbines of petrochemical plants. They play a vital role in transmitting power, driving turbine rotation, and realizing energy conversion.
At Songjie, our customized turbine shafts are mostly made of high-strength alloy forged steel. Through forging processes, internal defects are eliminated, and a uniform metal structure is obtained. This enables them to withstand high-speed rotation and long-term alternating loads, preventing fracture or plastic deformation under high torque, thus meeting the requirement of long-term continuous operation of petrochemical equipment.
Conclusion
To sum up, chemical industry shaft forgings play an irreplaceable role in the petrochemical field and are an important force driving the continuous development of the petrochemical industry. In addition, Songjie also provides various ship shaft forgings, which offer solid guarantees for the safe and efficient operation of the entire shipbuilding and maritime industry. In the future, we believe that our shaft forgings will play an important role in more fields, driving all walks of life towards a better tomorrow.
