Same-Layer Drainage Welding Machine Series Manufacturers

The Same-Layer Drainage Welding Machine Series is a key equipment for the construction of building drainage systems, specifically designed for the fusion connection of thermoplastic drainage pipes such as PE and PPR. Its welding quality directly determines the tightness and service life of the drainage system. Founded in 2011, Zhejiang Chenghong Machinery Co., Ltd. has provided the market with a variety of same-layer drainage welding machines (including manual, hydraulic, and automatic types) and supporting pressure testing pumps, relying on nearly a decade of in-depth experience in butt welding machine sales and professional manufacturing capabilities. It has become a representative enterprise in the industry with both standardized supply and customized services.

1. What are the key points of the core welding process for same-layer drainage welding machines?

The hot-melt butt welding process of same-layer drainage welding machines must strictly follow standard procedures to avoid problems such as joint leakage and blockage.

Pipe preprocessing is the foundation: After cutting, ensure the end face is perpendicular to the axis, remove burrs, and clean the connecting end face to keep it free of oil and dry.

Temperature and time control are crucial: The welding temperature for PPR pipes should be stably maintained at 260-280℃, and the heating time varies with the pipe diameter (e.g., 5 seconds for 20mm diameter pipes and 24 seconds for 63mm diameter pipes).

Insertion and cooling must be standardized: Immediately insert the heated pipe straight to the marked depth without rotation to form a uniform "double eyelid" joint. Do not move the pipe during cooling, and allow at least 3 minutes of cooling for 20mm diameter pipes.

Acceptance is indispensable: After welding, use a supporting pressure testing pump to conduct a water pressure test to verify the tightness of the joint.

2. How to select the appropriate model based on construction scenarios?

Different construction scenarios have significantly different performance requirements for same-layer drainage welding machines, so the selection must accurately match the needs.

Small-scale home decoration or narrow space construction: Prioritize manual welding machines for their portability and simplicity of operation, which can flexibly adapt to local renovation needs in bathrooms and kitchens.

Medium-to-large construction projects or batch construction: Hydraulic or automatic welding machines are more efficient, with stable pressure control and temperature adjustment functions to improve welding consistency and construction efficiency.

Special pipe diameters or customized needs: Choose models with strong compatibility and replaceable accessories. Some enterprises can provide customized services to quickly meet the welding needs of non-standard pipe diameters.

Project cycle requirements: For urgent start-ups, prioritize standardized models with stock availability to shorten the waiting period.

3. What are the common causes of poor welding quality and their solutions?

Problems such as air holes, uneven welds, and joint leakage after welding are mostly related to operation or equipment status.

Improper temperature setting: Excessively high temperature can cause pipe carbonization, while excessively low temperature results in insufficient melting. Calibrate the equipment temperature according to the pipe material to avoid deviating from the standard range.

Non-standard heating or insertion operations: Insufficient heating time or rotating the pipe during insertion will damage the integrity of the molten layer. Strictly control the time according to process parameters and maintain a straight insertion motion.

Wear of equipment components: Wear of welding torches, electrodes, or dies affects heating uniformity. Regularly inspect and replace vulnerable parts.

Impact of environmental factors: When the ambient temperature is below 5℃, extend the heating time by 50% to avoid slow melting caused by low temperatures.

4. Daily maintenance and troubleshooting skills for equipment?

Proper maintenance can extend the service life of the welding machine and reduce the risk of construction interruptions.

Key points of daily maintenance: Regularly clean the equipment shell and dies to remove residual molten plastic; inspect cables for wear and wiring for tightness; keep the cooling system unobstructed to prevent equipment overheating due to fan failure.

Common troubleshooting: Power supply failures can be initially judged by checking for broken cables or damaged switches; for control system malfunctions (e.g., unresponsive touch screen), restart the equipment after powering off, and contact professional maintenance personnel for complex issues.

Preventive maintenance: Establish usage and maintenance records to document fault handling; avoid long-term continuous operation and allow sufficient cooling time for the equipment; take moisture-proof measures when using in humid environments to prevent damage to electrical components.
