When it comes to stainless steel processing, there are various methods involved, such as processing sheets, coils, shapes, steel pipes, wires, and solid materials. Safety is paramount in industrial production, especially for tube/pipe manufacturers. Adhering to the principle of "safety first and prevention - focused" is crucial. This article serves as a comprehensive guide to the safety operation procedures for different types of stainless steel pipe - making machines, ensuring normal production and operation through strict regulations, staff training, and safety measures.

Why Safety Matters in Pipe Making
Accidents can easily occur during corporate production. tubes/pipe manufacturers must earnestly implement the principle of "safety first and prevention - focused", enforce safety measures, regard safety work as fundamental, and actively fulfill tasks. This is reflected in the chemical plant's safety work summary.
According to the steel tube manufactuers' specific conditions, it combines prevention with stable emergency response, strictly enforces rules and regulations, strengthens staff training in the "four disciplines" (process, labor, safety, and environmental protection), improves and implements safety organization systems, operational monitoring methods, and safety technology measures to ensure normal production and operation.
I. Safety Operating Procedures for Corrugated Pipe Forming Machines
1. Adjusting the Forming Rolls
Do not press the spring - loaded mandrel too tightly when adjusting the forming rolls. This can cause an overly small pitch and excessive pressure, overloading the motor, thus reducing efficiency and risking motor burnout with prolonged operation.
2. Shaping the Steel Strip
Shape the steel strip so that its left - side edge folds upward and smoothly enters the root of the spiral - shaped corrugated sleeve, ensuring it matches the spiral angle.
3. Positioning the Rotating Sleeve
Position the rotating sleeve so that its tongue aligns with the highest point of the die head's arc. This ensures minimal friction between the rotating sleeve and die head during operation.
4. Winding the Steel Strip
When winding the steel strip, manually rotate the pulley to engage the steel strip and secure the bite.
5. Placing the Flanging Wheel
Place the flanging wheel so that its tip contacts the die head at a proper distance from the corrugated sleeve's tongue tip. Avoid excessive tightening during adjustment to prevent the wheel tip from cracking the steel strip.
6. Keeping the Flanging Wheel in Contact
Keep the flanging wheel in close contact with the steel strip, allowing the upper and lower edges to slide and tighten between the flanging and edging wheels. Avoid excessive force when adjusting the edging wheel to prevent cracking or chipping of the flanging wheel.
7. Positioning the Embossing Wheel and Spur Gear
The embossing wheel and spur gear should be positioned so that their direction aligns with the angle of the folded edge. Adjust them to apply enough pressure to leave a clear mark.
8. Adjusting the Pressing Wheel
The pressing wheel should be slightly angled to the right based on the edge angle. Adjust the pressure by hand and fine - tune it during operation as needed.
9. Adjusting Components Without a Wrench
When adjusting the flanging wheel, edging wheel fork, and the cylinders for the embossing and pressing wheels, try not to use a wrench. Over - tightening can cause uneven force and deform the main shaft.
10. Splicing Steel Strips
○ Using a Spot Welder
It is best to cut the joint of the steel strip at an angle of about 30°, overlap the ends by about 3 - 4 cm and align both sides.Use a 6 - 8kw spot welder to weld 8 - 9 spots, locating them 3mm from the edge and at the center of the steel strip.
○ Manual Splicing
When splicing steel strips manually, cut a flat joint and trim off the sharp corners (5×45°). Then, fold back a length of about 5m, interlock the two ends, and hammer them flat and tight. Loosen the screws at both ends of the fixing spring, thread the steel strip through, and then tighten it. When passing the joint through the rolls, do it slowly to avoid disengagement.
II. Safety Operating Procedures for Double - Corrugation Pipe Forming Machines
1. Threading the Steel Strip Through the Guide Plate
Loosen the upper pressing wave wheel clamping bolt, feed the steel strip between the upper and lower pressing wave wheels, tighten the bolt, and adjust the bolt pressure so that the steel strip does not wrinkle.
2. Ensuring Even Pressure of Clamping Bolts
The pressure of the two clamping bolts on both sides of each pair of wave - pressing rolls should be even. After adjustment, the bolt pressure should not be too high. Uneven pressure of the two bolts can cause the formed steel strip to bend and wrinkle. If the steel strip from the coil is itself bent, the bolt pressure on the short side of the steel strip can be appropriately increased to ensure the formed steel strip is even and flat on both sides.
3. Feeding the Steel Strip Along the Spiral Direction
The wave - pressing rolls feed the steel strip along the spiral direction of the corrugated pipe. The adjustment angle of the wave - pressing roll box should usually be greater than the spiral ascending angle of the corrugated pipe by β2 - 3°.
4. Adjusting the Steel Strip Guide Plate
If the steel strip is bent or of inappropriate hardness, causing unevenness on both sides of the formed steel strip, the steel strip guide plate can be adjusted accordingly.
5. Maintaining the Worm Gear Reducer
The worm gear reducer uses No. 32 machine oil, and the oil level should not be lower than the level indicated on the oil gauge.
6. Adjusting the Main Shaft Bearings
The main shaft uses cylindrical roller bearings. The clearance should be adjusted so that the main shaft can rotate freely but without noticeable play. Lubricating grease should be regularly applied to the bearing area.
7. Lubricating the Mandrel and Forming Head
The fit between the mandrel and forming head shouldn't retain oil. After a long daily shutdown, apply a little lubricating oil to the junction of the spiral surface and mandrel before starting up to avoid dry friction.
8. Securing the Wave - Pressing Wheel
The wave - pressing wheel is fixed axially by a circular nut. After maintenance or adjustment, the nut should be tightened to prevent loosening.
III. General Safety Operating Procedures for Pipe Forming Machines
1. Avoiding Contact with Traction Wheels
Do not touch or approach the traction wheels when the pipe - forming machine is operating to prevent hand injuries.
2. Turning Off the Computer When Adjusting the Cutting Knife
Always turn off the computer when adjusting the cutting knife to ensure safety.
3. Preventing Arms from Entering the Servo Motor Cover
Do not put your arms into the servo motor cover to retrieve pipes while the machine is operating.
4. Keeping Hands Away from the Pipe - Dropping Box and Motor Safety Cover
Keep your hands out of the space between the pipe - dropping box and the motor safety cover when the cutting knife tray is working.
5. Checking the Water Source Before Starting
Check the water source before starting the machine. Only start the high - frequency system when cooling water is flowing.
6. Avoiding Unauthorized Changes to Computer Parameters
Do not change computer parameters during pipe - forming operations unless authorized.
7. Immediate Action on Faults
If a fault occurs, stop the machine immediately and notify maintenance staff for repairs.
8. Turning Off the Cutting Knife During Adjustments
Always turn off the cutting knife when adjusting the machine.
9. Staying Focused During Operation
Do not wear headphones, chat, or lose concentration during operation to maintain safety and efficiency.

Conclusion
Safety should always be the top priority when operating pipe forming machines. By following these safety operating procedures, operators can significantly reduce the risk of accidents and ensure a safe working environment. Regular maintenance, proper training, and adherence to safety guidelines are essential for the efficient and safe operation of any pipe forming machine.
