The designers and developers of the accessories for extracting oil use the connections with trapezoidal thread in the most loaded areas of the equipment.
It is characterized by increased strength towards tensile loads, has more tough structure than other thread kinds. Due to symmetrical airfoil section in shape of trapezoid, these loaded are distributed more evenly along the turns, and the connections themselves have high strength.
However, great tension caused by increased friction appears on the thread grooves what can affect quality and service lifetime of the connections in a negative way.
To provide standard mounting and operating of the couples, pipes, and other items with trapezoidal thread, MODENGY 1026 coating based on molybdenum disulfide, a solid lubricating material having high load-carrying capacity and anti-score properties is used.
It forms a thin lubricating layer of the parts that reduces friction, effectively prevents scores from forming by excluding direct contact of the threaded surfaces in process of screwing. One of the basic advantages of MODENGY 1026 is no need in refreshing after dismantling the connections as the threaded parts treated with this coating can be unscrewed and then screwed again multiple times.
This coating is convenient to apply out of the aerosol can or a spray-type gun, it cures at room temperature. MODENGY 1026 is used by the leading manufacturers of the equipment for oil and gas wells development, they apply the material onto the threads under conditions of their enterprises before sending them to the operating site.
Due to application of MODENGY 1026 coating, increase in multiplicity of mounting/dismantling of the connections with trapezoidal thread is provided as well as reduction of friction and tension on the thread grooves, and labour-intensity of the processes of mounting/dismantling.
