 De: Denotes the outside diameter of PPR pipes, PE pipes, and polypropylene pipes.

• DN: Denotes the nominal diameter of polyvinyl chloride (PVC) pipes, cast iron pipes, steel-plastic composite pipes, and galvanized steel pipes.

• d: Denotes the nominal diameter of concrete pipes.

• ф: Denotes the nominal diameter of seamless steel pipes, specified in the format of outside diameter × wall thickness (e.g., ф100 corresponds to 108×4).

Key Safety Precautions for Down-The-Hole (DTH) Drill Rig Operation

Successful and safe DTH drilling relies on strict adherence to core procedures. 

Core Principle: There are no shortcuts to safety.

The engine is the heart of the drilling rig. Special attention should be paid to engine maintenance in winter to ensure smooth starting and normal operation, and to prevent damage caused by low temperatures.

The pilot hole is the first step of construction, and subsequent reaming and pipe pulling operations are carried out on this basis. The quality of the pilot hole, such as the turning radius of the deflecting section, the smoothness of the trajectory curve, and the position of avoiding underground obstacles, directly determines the success or failure of subsequent pipe pulling operations, so the construction of the pilot hole must be done carefully.
