Drilling hose is a kind of hose used to transport mud, oil, water and other media in the oil drilling industry or subgrade settlement wells. Oil drilling hoses, also known as high-pressure hoses or drilling hoses, are characterized by high pressure resistance and can be used normally in harsh environments. As a professional drilling tube manufacturer, we will take a comprehensive understanding of the drilling tube.

 

Drilling hose application
 

Mainly used in oil drilling, mud or water, muddy water mixture, sediment water mixture, fracturing fluid delivery manifold system. The flexible connecting pipe between the top of the rig riser and the mud pump at the bottom of the rig is the hose. Because the drilling machine is a heavy-duty machine and the environment of the drilling operation is harsh, the positioning of the riser and the pump body may be in error. Then, the softness and high pressure resistance of the drilling hose can adjust the displacement well, thus ensuring the normal operation of the rig. It can also reduce or eliminate the vibration and noise between the pump body and the rig riser, avoid the resonance and prolong the service life of the rig.

 

Drilling the composition of the hose wall
 

The drilling hose is composed of an oil-resistant or wear-resistant inner rubber layer or a 304 inner armored inner tube, a carbon fiber reinforced layer, a middle rubber layer, a multi-layer steel wire or steel cord reinforcing layer, and a weather-resistant outer rubber layer. The inner rubber layer selects a suitable synthetic rubber according to the different fluids to be transported, and the steel wire reinforcing layer is generally wound with four or six layers of multi-strand steel wires. The four-layer steel wire has a pressure resistance of 35 MPa. The six-layer steel wire is resistant to pressure of 70 MPa.

 

Drilling hose standard and connection method
 

Drilling hose implementation standards are: API SPECK 7K.SY/T5469-92. Drilling hoses can be used to transport a variety of different media, such as mud, oil-based mud, and can withstand the corrosion of hydrogen sulfide, cold can be used to transport steam instead of cloth steam hose, drilling hose and drilling machine is mainly through the law Lan, hammering is connected by a high pressure and other joints.

 

Drill hose specifications
 

There are many types of drilling hoses, such as DN51*4SP, DN64*4SP, DN76*4SP, DN89*4SP, DN102*4SP, DN127*4SP, DN152*4SP, etc., 4SP stands for four-layer wire winding. The six-layer steel wire is represented by 6SP.
