The pipe ends, both at the beginning and end sections, are typically left uncoated for about 10 centimeters to allow for welding operations. However, after welding is completed, insulation must be applied. Additionally, pipes that are used uncoated must also be insulated.
Moreover, any damage to the coating of the pipes during operations must be repaired. The bitumen kettle melts the required bitumen and brings it to the desired temperature, allowing the pipe insulation process to be carried out smoothly.
