Product Introduction:
In the petrochemical field, the cross shaft is a key component in mechanical transmission structures (such as widespread couplings, go - shaft daily joints, etc.). It is generally talking used to transmit rotational movement and torque between intersecting shafts. Its format and average overall performance right away have an impact on the transmission efficiency, reliability, and safety of the equipment. The go shaft has immoderate electricity and fatigue resistance. It adopts precision machining processes, sealed and leak - proof designs to end the leakage of lubricating oil and the intrusion of exterior dust/corrosive media, making positive prolonged - time duration reliable operation in the pretty polluted and humid environment of the petrochemical industry.

Q1. Can your forged cross shaft withstand high pressure and corrosion in oilfield environments?
Yes. Our cross shafts are forged from high-strength alloy steel with strict heat treatment, featuring excellent pressure resistance, fatigue resistance and impact resistance. We can also provide anti-corrosion surface treatment according to oilfield and petrochemical working conditions.
Q2. What is the hardness range and mechanical performance of your cross shafts?
The hardness is generally controlled at HRC28–38 (customizable per requirement). Stable forging and heat treatment ensure uniform hardness, high tensile strength and good toughness, suitable for long-term heavy-duty operation in petrochemical equipment.
Q3. Do you provide material certification and third-party inspection?
Yes. We supply material test reports (MTC), hardness reports, UT/MT reports for each batch. We also support third-party inspections such as SGS, BV and TUV to meet international petrochemical industry standards.
