The manufacturer of spiral tubes notes that, under normal operating conditions, the spiral tube will naturally become slack. If a large tractor lacks proper support from its work platform, the spiral tube may loosen and, as it is twisted and driven by the rotating shaft, could lead to safety incidents. For models equipped with a work platform, during steering, if any component of the tractor becomes caught, it can also pull on the spiral tube. To mitigate this risk, an elastic rope is used to suspend the spiral tube at its midpoint, preventing slackness. A practical approach is to cut the connecting pipe into strip‑like segments and join them together; alternatively, a single continuous spiral tube can serve as a suspension system—both methods are highly effective.

　　 Spiral pipe manufacturer It is stated that manufacturing enterprises produce a wide variety of spiral pipes, and during the unloading process, damage to seamless steel pipes is unavoidable. Specific details are as follows:

　　1. During routine handling, transportation, and storage, spiral pipes shall be provided with external packaging to prevent detachment and damage.

　　2. If the buyer has specific requirements regarding the packaging of the spiral pipes, such requirements shall be specified in the contract; otherwise, the supplier shall select appropriate packaging materials and methods.

　　3. Packaging materials must comply with applicable regulations. Where no specific restrictions apply, they should be suitable for their intended purpose and help prevent waste and air pollution.

　　4. If the customer requires that the outer surface of the spiral pipe remain free from dents or damage, a protective device can be installed at the center of the pipe. Such protective devices may include plastic sleeves, hemp ropes, fiber cloth, plastic wraps, pipe caps, and similar materials.

　　When starting the helical coil under normal conditions, three points should be noted:

　　1. During installation, the connectors on both sides must be securely fastened to prevent air leakage; otherwise, after prolonged storage, frequent inflation may result in reduced fuel efficiency.

　　2. According to the spiral pipe manufacturer, the spiral pipe naturally becomes slack during normal operation. If the large tractor lacks proper support from the work platform, the spiral pipe may loosen and become distorted by the rotating shaft, potentially leading to safety accidents. For models equipped with a work platform, when turning, if any component of the tractor becomes snagged, it can also pull on the spiral pipe. To mitigate this risk, an elastic rope is used to suspend the spiral pipe at its midpoint, preventing slackness. A practical approach is to cut the connecting pipe into strip‑like segments and join them together; alternatively, a single continuous spiral pipe can serve as a suspension system—both methods are highly effective.

　　3. In the cold winter conditions of northern regions, choose products with high toughness to prevent the raw materials from becoming brittle in low temperatures. Once they become brittle, they can easily break, compromising driving safety.

　　What are the welding requirements for spiral pipe welding?

　　1. If the gap is too small, it can exacerbate the proximity effect, resulting in excessive heat generation during arc welding and leading to weld burn‑through; alternatively, if the weld undergoes extrusion or forming, large depressions may form, compromising the surface quality of the weld.

　　2. If the gap is too large, the proximity effect is reduced, the eddy current heating is insufficient, and the weld fails to achieve tight intergranular bonding, resulting in lack of fusion or cracking.

　　Spiral pipe manufacturers explain that after heating the two edges of the pipe material to the welding temperature, gentle pressure from the squeeze rolls causes the shared metal grains to interpenetrate and recrystallize, ultimately forming a robust weld. If the applied force is too low, fewer grains will fuse together, reducing the compressive strength of the weld metal and increasing the likelihood of cracking under load. Conversely, excessive squeezing can force the molten metal out of the weld zone, not only diminishing weld strength but also generating substantial internal and external burrs and potentially leading to defects such as incomplete fusion or overlapping welds.
