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
