Product Description

Oilfield Hoses for drilling facility

Yitai is a professional oilfield hoses manufacturer in China. The oilfield Hoses for drilling facility, also known as rotary drilling hose, is a specialized high-pressure hose used in the oil and gas production industry to transport drilling mud and other fluids between the drilling rigs and the drilling equipment. These hoses are designed to withstand high pressure and harsh conditions encountered during drilling operations. They are typically reinforced with multiple layers of high-strength steel wire and resistant to abrasion, oil, and various chemicals. The drilling hose plays a crucial role in safe and efficient operation of oil drilling rigs.

Our company imports advanced rubber raw materials applied in the fully automatic batching and rubber mixing workshop.

The product formula is developed by the Polymer Laboratory of Tsinghua University, which endows our products with excellent high-temperature and chemical corrosion resistance. At the same time, a fully automatic rubber mixing equipment for high-precision processing and computer-controlled independent rubber mixing are token to ensure the stability of the product. We also use the most advanced wire winding machine in China, which has the characteristics of large caliber and high precision. High-strength steel wire serves as the skeleton layer, and the product has an overall three-layer cord protection layer inside and outside, making the product more sturdy and with stronger pressure bearing capacity. The company are tested with various certificates and certifications, such as ISO,MA,MSHA,GOST,CNAS,etc is a direct sales with our own factory, operating for many years.

FAQ: What’s drilling hose?Drilling hose is made of a bonded construction containing steel and rubber materials. Drilling hose is designed for flexible connection between standpipe and swivel (rotary drilling)or between pump and standpipe(rotary vibrator) for pumping mud at extra high pressure in oil drilling and exploration work, meets the high demands of directional drilling and down linking with negative pressure pulses and elevated temperatures, the drilling Kelly hose can also be used as a motion compensation hose for stabilization of rotary drilling and pumping equipment against vertical wave action on offshore drill platforms,the motion compensation hose is not recommended for phosphate ester fluids.

Also known as High Pressure Flexible Rubber Hose, High Pressure Cement Hose, Hose used for Oilfield, High Pressure Rubber Hose, Marine Engineering Hose, Oil Drilling Hose, Well Cementation System Hose, Offshore and Land Drilling Rig Used Hose, API 7K Integral joint High Pressure Cement Hose , High Pressure Cementing Hose, Cement Slurries Conveying hose, ect.

FAQ: What are their applications? Flexible connection between upper end of neutral pipe and top driver/rotary device in drilling and work over operations, and between pump and lower end of riser, to pump mud at high pressure in oil drilling and exploration workFAQ: What is the most common construction of a high pressure drilling hose?Tube: Modified Nit rile, black, Specially designed for handling abrasive, corrosive, and oil drilling mud.Reinforcement: Multiple layers of textile fabric and steel cable, with one layer middle rubber placed between cable layersCover: Modified Nit rile, black, specially designed Ultra abrasion cover is resistant to abrasion, corrosion, cutting, gouging, oil and weather.FAQ:How to maintain high pressure drilling hose?1.Cleaning

Clean union,thread,sealing surface,sealing ring and keep them in good condition before installation.


2.Check 2.1 Tags,moulded or bonded marking,conformance label on hose shall be intact.

2.2 Hose body shall be free of visible deformation or cracks.

2.3.Hose lining and cover surfaces shall be free from serious wear,delamination,kinking crack,bubble and soft spots.

2.4 Sealing surfaces of union and flange shall be free from corrosion and cracks.

2.5 Sealing ring shall be free from corrosion and deformation.

2.6 Bolting shall be free from corrosion and deformation.

3.Connection and fastening

3.1 Hose shall be handled by lifting or moved by bracket,do not allow dragging and moving on ground.

3.2 After installation,hose should be in relax,free from severe bend,twist,distortion and crush.

3.3 Cross contact with other equipment and facilities shall be avoided.When distance is less than 30mm,rubber blocks or cushion blocks shall be used for effective separation.

3.4 Do not use chains and wire ropes to directly bind hose body for lifting;Nylon sling can be used to bind hose rigid end,or safety clamp can be installed at designated position on hose for lifting.



4.Limitation of operating pressure:

Stable working pressure for conventional fracking operation should be within 90%rated working pressure;

Stable working pressure for factory fracturing should be within 85% rated working pressure.

5.Limitation of operating flow:Max.flow shall not exceed recommended value .

Internal fluid temperature range:-20℃-121℃.

6.Environment temperature range for hose:-46℃-50℃

7.Only after inside pressure is completely released,replacement or rectification about manifold can be conducted.

8.For factory fracturing,patrol inspection shall be done after each operation,and inspection about fastening shall be carried out after each three operation
