Automatic Welding Technology by Multiple Inspections
We have the perfect automatic welding technology to guarantee the flatness and finish of the weld seam, which can ensure the best level of hardness and flatness.
Our semi-automatic welding technology also guarantees the stability of the weld and the quality of the weld seam.
Cutting-edge Technology for Precision Pipe Fitting
Bending process:
The pushing process has been eliminated in our bending process as it is prone to uneven wall thickness, with thin walls at the opening and thicker walls at the base. We have improved this process, resulting in more uniform wall thickness, better interior surface protection, and easier polishing.
Annealing process:
Our pipe fittings can be annealed after bending by heating them to 1040-1070 degrees Celsius, and then slowly cooling them. This improves cutting performance, reduces residual stress, stabilizes dimensions, reduces deformation and cracking tendencies, refines grain structure, adjusts the organization, and eliminates structural defects. This ensures that the pipe opening is more rounded, minimizing the spring-back after the pipe fitting is formed, and ensuring that it falls within the tolerance range.
Spherical plunger process:
Our spherical plunger process ensures better fitting between the ball and the pipe fitting, with better interior surface protection, more precise pipe fitting angles, and more accurate dimensions.
Weld Seam Treatment
Hope Machinery's high clean pipe are made from 2B cold rolled steel coils as raw material, with longitudinal welding technology to achieve complete penetration, and mature weld treatment technology to ensure qualified welding. Our wire turbine flaw detection system ensures that every product is free of impurities. With perfect quality inspection system and advanced mold calibration system, we can ensure that the wall thickness difference of the welded seam is controlled between 0.02-0.03MM.
Complete traceability is provided for each product by providing all the necessary production process data. Starting with certification and incoming inspection of raw materials, through process quality control, final inspection, labeling and packaging. Full inspection is utilized for all BPE compliant products to ensure that all products that reach the customer meet ASME BPE standards.
HOPE offers unparalleled surface quality
Surface treatment is deeply rooted in HOPE's tradition, and we constantly strive to enhance our processes through innovative production techniques and tailored solutions for our clients. Our focus is always on achieving higher standards of quality in everything we do.
