Wellnit Machinery Manufacturing Co., Ltd. recently completed a factory pre-delivery test for an ISE-630 internal expanding pipe beveler ordered by a new customer. The test took place at Wellnit's facility in Lishui, Zhejiang Province, with the goal of ensuring that this pipe end beveler reaches the customer in perfect working condition, ready for immediate field use.
Product Tested: ISE-630 Internal Expanding Pipe Beveler
The ISE-630 is an electric internal expanding pipe beveler with a working range of 300-600 mm (about 12 to 24 inches). Its internal expansion design allows the machine to self-center inside the pipe, making it particularly suitable for high-volume pipe beveling applications in explosive or fire-sensitive environments. Typical industries include petroleum, chemical processing, natural gas transmission, food and beverage production, boiler manufacturing, pharmaceutical plants, and nuclear power generation.
Pre-Delivery Test Objective
Ensure that every pipe end beveler leaving the Wellnit factory operates flawlessly, so customers can begin using it immediately upon delivery with zero downtime.
Pre-Test Preparation
The Wellnit quality team began by checking all machine components for completeness. Standard wrenches, tools, and test pipe samples of various diameters (300–600 mm) were prepared for the actual beveling trials.
Core Test Procedure - Step by Step
Step 1: Expand and Secure the Machine Inside the Pipe
The technician selected the appropriate expansion blocks based on the inner diameter of the test pipe. The expansion mechanism was inserted into the pipe, where the self-centering design automatically positioned the machine. Turning the expansion nut clockwise expanded the blocks outward, locking the pipe end beveler firmly in place without any tilting. Proper expansion is the single most critical step in the entire setup process.
Step 2: Install and Position the Cutter
After the machine was locked inside the pipe, the cutter was installed. A gap of approximately 2 mm was maintained between the cutter tip and the inner wall of the pipe before cutting began. This clearance prevents blade impact during startup.
Step 3: Connect Power and Jog Start
The electric motor (2000W, with working voltage of 220–240V 1PH) was connected to the power supply. The technician jogged the power switch briefly to observe the initial rotation and listen for any unusual noise or vibration - all was normal.
Step 4: Feed and Beveling
With the motor running, the feed handle was rotated clockwise. Critical rules were strictly followed: rotate the handle exactly one notch per revolution of the cutter head. Feeding too quickly would cause the cutter to "stall" - a condition where excessive cutting force damages the tool. Maintaining a slow, steady feed keeps the internal expansion pipe beveler in optimal operating condition.
Key Commissioning Step - Expansion Verification
The Wellnit engineer emphasized that verifying the machine is properly expanded inside the pipe is the most important commissioning step. A machine that is not tightly expanded against the pipe wall will shift during cutting, causing tool breakage, poor surface finish, or damage to the pipe end beveler itself. Operators must always confirm that the machine is neither loose nor tilted before cutting begins.
Test Results
| Parameter | Result |
|---|---|
| Configuration completeness | Fully compliant |
| Expansion lock | Secure, no tilt |
| Tool clearance | 2 mm correctly set |
| Rotation observation | No abnormal vibration or noise |
| Feeding and cutting | Stable, smooth bevel surface |
| Final verdict | All systems pass - machine approved for shipment |
The test confirmed the ISE-630 pipe end beveler operates smoothly, with stable mechanical performance and consistent bevel quality. All components were verified complete, and the machine runs without any abnormality.
