I. Pressure Adjustment Steps 1. Preparation Ensure the equipment is stopped, check the hydraulic oil level is normal, and ensure there are no leaks in the pipeline. Turn on the pow

After welding HDPE pipes, a visual inspection should be performed immediately after the weld has cooled to ambient temperature and is safe to touch. This is typically completed wit

I. Visual Inspection: Immediately assess the basic weld quality. After welding, once the weld has cooled to a safe touch (usually over 20 minutes), a 100% visual inspection should

I. Air bubbles or pores in the weld This is one of the most common internal defects during welding, manifesting as voids or honeycomb structures inside the weld, severely affecting

I. Process Parameter Control: Ensuring the "Internal Quality" of the Weld The heating plate temperature must be accurately set: 210±10℃ for PE80 pipes, and 225&plu

🔧 I. Preparation before calibration Environmental requirements: Place the equipment in an indoor environment of (23±5)℃ and humidity ≤85% for 2 hours to avoid the influe

I. Structural Durability: Is there irreversible deformation or fatigue damage? Structural components are the "skeleton" of the equipment. Plastic deformation or cracks wi

I. Improve structural durability: Reduce metal fatigue and ensure rigidity and stability. The machine frame and guide rails are subjected to high-load forging forces over long peri

I. Judging Incomplete Welding by the "Double Eyelid" Edge The "double eyelid" is a double-ringed edge formed by the even overflow of molten material, a sign of
