Drilling hose introduction

  The full name of the drilling hose is called "Rolling Drilling and Shock Absorbing Rubber Hose". It can also be called "Drilling Equipment Hose". As a professional drilling hose manufacturer, let's introduce its application range and structure.
 

         
         Drilling hoses can be used in drilling, cementing, workover and petroleum geological exploration, small drilling rigs and water mining. Drilling hose is a flexible joint in mud manifold, cementing manifold, throttling and killing manifold, etc. It is commonly used to transport water, oil-based mud, cement slurry, well washing fluid and normal temperature water under high pressure. . The drilling hose can work normally between -30 and 82 °C.

 

 

        The structure of the drilling hose is composed of an inner rubber layer, an inner rubber protective layer, a middle rubber layer, a steel wire wound reinforcing layer and an outer rubber layer. The drilling hose is made of nitrile rubber which is resistant to oil, wear and acid and has good acid and alkali resistance. The tube reinforcement layer usually adopts 2 to 8 layers of strong steel wire winding structure, and the steel wires are bonded together by film to form a firm whole. Drilling hoses are usually made of neoprene which is resistant to oil, abrasion and weathering. It can be adjusted according to the specific needs of customers.

       
         The above is the main knowledge of the drilling hose introduced to everyone, I hope to help everyone.

How to check the quality of rubber oil tubing

Rubber oil hose is a hose that is often used in daily life. The safety check of rubber hose is very important. Once it has oil leakage, cracking and other faults, it will directly affect the safety of the whole machine operation. How to verify?

Rubber tubing refers to a hose composed of rubber and steel wire that is specially used to transport oil. The quality of rubber tubing can be easily tested by the following three tests.
1. Rubber tube hydraulic test: This is mainly to test whether the rubber tube and the assembly are leaking, deformed and destroyed under the verification pressure for 30s-60s. There is also a pressure deformation test, which is held for 1 minute under the specified pressure, and measures the length and outer diameter of the hose and the torsion angle and bending.
2. Rubber tube burst pressure test: It refers to the pressure at which the hose is blasted at a specified boosting speed.

 3, rubber tube leakage test: This is stored under the static pressure of 70% of the small burst pressure for 5min, repeated once, check for leakage or damage. The above is one of its inspection standards. In order to get a rubber tube of better quality, the rubber tube is indispensable for inspection standards.

Couplings:

Swaged couplings. API standard flanges or equivalent of your choice.

Temperature: 

-4℉ to +180℉ (-20℃ to +82℃) continuous service.

Options: 

Accessories such as safety clamps, hose lift eyes and stainless steel armor are available upon request.

                             

Test:

Each hose is tested at 10000psi or 15000psi for 15 minutes. Pressure test graph, test certificate and letter of conformance are issued for each hose.

Specification:

5,000psi W.P. – 10,000 psi Test-12,500 psi Minimum Burst-Grade D

7,500psi W.P. – 15,000 psi Test-18,750 psi Minimum Burst-Grade E

Pup Joints

1. Product Overview

Pup joint is cementing and fracturing equipment delivery High Pressure Fluid Control Products. Widely used in the acidic operating environment (excluding containing CO2, H2S sour gas operating environment) in the high-pressure discharge line, input line, a temporary flow line, well testing, and other high-voltage transmission lines on pipelines. Pup joint specifications are 1 in ~ 4 in, length 0.5 m, 1 m, 1.5 m three kinds, rated working pressure 42MPa ~ 105MPa, working temperature -46 ℃ ~ 121 ℃.

⑴.The high pressure pup joint designed and manufactured by our company is forged by high quality structural alloy steel. Terminal union is forged together with pipe, which is able to avoid disassembling and ensure good sealing, small weight, convenient use and fast installation. high pressure Pup joint has various specifications including 1"~4" and lengths including 1’, 2’, 3’, 4’, 5’, 6’etc, rated working pressure is 42MPa ~ 105MPa. Any specification of pup joint or even integral pup joint special for acid environment is available according to users’ needs;

⑶. Activities elbow have to undergo rigorous testing and nondestructive testing hydrostatic pressure in the factory. Disassemble or repair, you must be hydrostatically tested. Rated working pressure test pressure regulator 10 minutes, without leakage (Note: pressure test should be drained before the air in the system). 

⑷. Pup joint should be regularly using ultrasonic thickness measurement of wall thickness, it is recommended once a month, if not reach the effective thickness value, should be replaced immediately. Replacement should be performed in conjunction with other pipelines.

⑸. Pup joint can not operate in continuous or frequent rotation swing working condition; can not be immersed in water or working underwater. Can not withstand axial load elbow work activities.

⑹. When the installation Pup joint, should fill seal grease, and manually check each joint rotation is flexible, without jamming. Operators should wear goggles to prevent the installation of a small debris flying eye injury.
