Today we were delighted to hear from one of our customers in Australia.
They reached out to purchase spare parts for a pipe threading machine supplied by SUNTECHMACH about 15 years ago.
It is truly inspiring to know that the machine is still operating smoothly after more than a decade, proving once again the durability, reliability and long-term value of SUNTECHMACH equipment.
We sincerely appreciate the customer’s trust in SUNTECHMACH, and we will continue to provide professional technical support and spare parts service to ensure every SUNTECHMACH machine keeps performing at its best.
At SUNTECHMACH, we believe that quality defines the brand. From engineering design to supply chain management, production control, testing, and final inspection, we have established a comprehensive and rigorous quality assurance system to ensure that every machine delivers stable performance, long service life, and high reliability.
100% inspection of critical components, including motors, gearboxes, bearings, and sealing systems.
Stable supplier network, partnering with certified manufacturers (ISO, CE, etc.).
Imported sealing parts for hydraulic systems and grooving/bending machines to ensure pressure resistance and durability.
As the gearbox is the most critical part of threading and grooving machines, SUNTECHMACH maintains full control by:
Assembling and tuning all gearboxes in-house by our engineering team.
Conducting three-stage meshing tests: high speed, low speed, and load simulation.
Ensuring gear accuracy, clearance, and noise level meet standards before moving to the next process.
This is one of the key reasons SUNTECHMACH machines can operate stably even after 10–15 years of use.
A “Three-Check System” is implemented during assembly:
First Article Inspection – Supervisor approval required for the first unit at each workstation.
Patrol Inspection – QC team conducts checks every two hours on critical points.
Final Process Inspection – Full functional testing after assembly is completed.
Key inspection items include:
Electrical function testing
Load running test (with steel pipe simulation)
Hydraulic pressure endurance test
Noise & vibration test
Secondary check of fasteners and overall appearance
Before packaging, each SUNTECHMACH machine must undergo 20–40 minutes of real-operation simulation, depending on the machine type:
Threading machines: full-size TPI cutting test + automatic feed test
Grooving machines: groove depth consistency check
Pipe cutters: perpendicularity and cutting accuracy test
Butt-fusion welders: heating plate temperature stability test
This ensures every unit has passed real-world work conditions before leaving the factory.
The final audit before shipment includes:
Recording product serial numbers
Verifying full accessory list
Packaging vibration resistance check
Carton batch record and barcode tracking system
All quality data is traceable.
The long service life of SUNTECHMACH equipment—some units still running after 15+ years—comes from:
High-grade materials
Wear-resistant treatment on critical components
Robust motor & gearbox structures
Advanced heat-treatment processes
Long-term spare parts supply system
We deliver not just machines, but lasting value.
Regular follow-up with overseas clients
Customer suggestions integrated into engineering evaluations
Continuous product upgrades
24/7 technical support team
This system ensures SUNTECHMACH products consistently meet global market requirements.
