FAQ

Q1: Is this fluid end fully interchangeable with original SPM TWS 2250?

A: Yes. Our HNA 2250-TWS fluid end shares identical overall dimensions, hole layout and interface standards with SPM TWS 2250. All matching spare parts can be directly mounted without modification.

Q2: What is the maximum rated working pressure of this fluid end block?

A: The rated well service pressure reaches up to 19,000 PSI. To prolong service life, the actual operating pressure shall not exceed the pressure limit corresponding to the selected plunger size.

Q3: What raw materials are available for the forging body?

A: Standard options include SAE 4330V, SAE 4330V-MOD, 17-4PH and 15-5PH stainless steel. Custom special alloy materials can be produced to match clients’ working conditions.

Q4: What strengthening technology is adopted for the internal flow channels?

A: Two mature technologies are optional: auto-frettage prestressing treatment and cold rolling reinforcement. Both methods eliminate internal tensile stress and prevent fatigue cracking under long-term high-pressure circulation.

Q5: What continuous heavy-duty operation can this fluid end withstand?

A: It is designed for 10-hour daily high-performance operation, 6 days per week under severe fracturing conditions, with service life performance exceeding API standard requirements.

Q6: Which plunger diameters are compatible with this fluid end module?

A: It supports 4", 4-1/2", 5"and 5.5" plungers, covering construction demands from high-pressure small displacement to low-pressure large displacement.

Q7: Do you offer non-API customized fluid end blocks?

A: Yes. We supply both standard API-compliant products and non-standard customized designs based on clients’ special well service equipment parameters.

Q8: What inspection documents and certificates can be supplied with each unit?

A: Every fluid end is marked with a unique heat traceability number, accompanied by ASTM A370 mechanical test report, ASTM A388 ultrasonic test report and material certificate.
