Straight copper pipes of fixed length, produced by casting, rolling, stretching, and cutting to size, have the advantages of uniform wall thickness, good straightness, good corrosion resistance, long service life, good weldability, easy flaring and processing, and are environmentally friendly and recyclable. They are widely used in the air conditioning and refrigeration industry, building water supply and drainage, gas transportation, HVAC and heating, industrial equipment, electrical applications, and other industries.

Instructions:
1. The item marked with an "X" in the table above indicates that it cannot be produced, while the item with a specified wall thickness tolerance range indicates that it can be produced;
2. The delivered weight of mosquito coil coils includes the gross weight of packaging materials (such as heat-shrinkable film and caps). They are packaged in cardboard boxes, with components in square trays, and shipped in full trays;
3. The nominal length of mosquito coil is 15 meters or 30 meters, with a length tolerance of ±0.10 meters;
4. Both single-layer and double-layer mosquito coil holders are available. Typically, a single-layer holder measures 15 meters, while a double-layer holder measures 30 meters.
