State-of-the-art rotary drilling hose at an affordable price
Letone Hydraulic Technology Co., Ltd., located in Henan Province, China, has developed into a strong competitor in the production of drilling rotary hoses in oilfield drilling rig systems. Thanks to more than 20 years of hard work, our rotary/drilling hoses have been widely accepted by distributors and contractors all over the world including the United States, Mexico, Brazil, South Africa and other countries and regions.
Provide oilfield rubber hose and end fittings
Flexible drilling rubber hose plays an important role in oil extraction. They should withstand high operating pressures, extreme operating temperatures, wear and other inferior elements. The maximum working pressure for steel cable strength members is up to 15,000 psi. The steel wire is usually galvanized or copper plated to improve the resistance of the steel wire to rust and corrosion. Since the rebar is thick, the hose should be handled or stored in the correct way to avoid kicking or pinching. They will greatly reduce their rated working pressure.
As an experienced professional hose manufacturer, Letone has obtained the Safety Certificate of Approval for Mining Products, certificate of MSHA, API Type Approval (API 16C and API 7K), ABS Type Approval (Drilling Equipment and Flexible Wire Braided Rubber Hose Assembly), GOST certificate, Lloyd's Fire Test Certificate and meets the requirements of quality management systems such as ISO14001:2015, ISO9001:2015, API Q1, IATF 16949:2016, etc. Letone also holds the environment management system international certification issued by IMS (comply with ISO14001:2015 standard). The Letone Testing Center has obtained the Laboratory Accreditation Certificate issued by CNAS in 2016. There are more than 20 laboratories include impulse test laboratory, burst test laboratory, fire test laboratory, salt spray laboratory, etc. The testing report is identified as objectivity, accuracy and authority.
New high pressure hydraulic hose replaces rubber hose in oil and gas applications
Products used in the rigorous oil and gas industry must be resilient and of high quality to properly support these complex operations. Hoses and connections must be safe, versatile and efficient. Rubber hoses have their limitations when used in harsh environments. One of the problems is bubbling of the inner tube. Foaming is caused by fluid seeping into the rubber core tube over time. When the pressure is released quickly, the fluid will try to escape quickly and damage the rubber core tube, causing blisters, which in turn cause leak paths in the core tube. Letone Hydraulics has developed high pressure hoses specifically for subsea applications. The core tube is made of nylon, time- and field-proven for use in subsea applications, and chemically compatible with subsea control fluids.
Offshore Drilling Mud Hose
Slurry hoses are bulk delivery hoses for the offshore oil and gas industry. For transfer from shore to ship and onboard installation of drilling fluids, including most fluids used in hydrocarbon drilling operations. Especially those containing large amounts of suspended solids, emulsified water or oil and all types of water-based, oil-based and synthetic-based drilling fluids. Drilling, completion and workover fluids sometimes referred to as muds, although essentially free of solids, are not strictly believed to be successfully used with this hose.
1,Question: What are your hose products?
Solution: The main material of our hoses is rubber. In order to cope with different hose usage conditions, there will be different hoses, such as high temperature resistant steam hoses, corrosion resistant chemical delivery hoses, ultra-high pressure cleaning hoses, Petroleum drilling hoses, etc.
2,Question: What certificates do you have?
Solution: Each hose we produce has obtained corresponding certificates, especially ISO and ABS system certificates, which is the recognition of our production capacity.
3,Question: How long is your lead time?
Solution: Usually the delivery period is 15 days
4,Question: How long is the service life of your hoses?
Solution: Different hoses have different service life, but the hoses we produce are relatively long-life hoses on the basis of standards
