Success Case

FAQ | What materials are commonly used for chemical pipelines
   
     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.

 

Frequently Asked Questions | How high is the high temperature resistant 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.
