Higher pressures, well-treatment chemicals, longer frac times and other critical-service conditions place emphasis on seal integrity. When last-minute completion changes are possible, the TET is a good investment because no shop modification is needed to adapt it to any type of tubing completion. The HP is the product identifier, the HY references hydraulic piston, and the 90 refers to the piston size. These fully symmetrical valves effectively seal wellnead flow in either direction.

This can potentially damage the actuator. The wwellhead is so simple that, in the event of logistics problems, it can easily be installed by a competent drilling crew. The HP-HYW surface safety valve is a hydraulically controlled actuator that is operated by a closed hydraulic system completely independent of well fluids and pressure. Flanged, studded, male thread or female thread 2. The second port is designed to accommodate the electrical conductors that pass the current between the surface cable and the subsurface cable that goes to the pump.

Metal-to-metal welllhead bonnet assembly: For outlet working pressures of 15, psi, straight-thread, metal-tometal seal VR plugs are standard. Business Activity Review Health, safety and environment HSE performance is a core value and will be managed as an integral part of our business to benefit employees, neighbors and shareholders. The HP-HY actuator will be sized to open the valve against full differential with the available control pressure. FMC Energy Systems is proud of our sealing designs, and we would like to share our seal technology with you so you can take it into account next time you specify your equipment.

They are also guided by welhead reports including photographs and schematics that document the size, working pressure, serial numbers and manufacture of each piece of equipment on each wellhead. The smaller tubing head flange allows for economical temporary tubingless completions and for traditional tubing completions.

The externally energized seal requires mechanical force to effect a seal. With or Without Lockdown Screws 2.

Threaded End Weight Lbs. Reference grease guideline G Failed, seat leak on last test 50 ft. And if one seal in a wellhead fails, it can blow the budget with lost production and workover time. Nitrited wellhead lapped gate and seat provide extended life expectancy. The HP-HYW actuator will be sized to open the valve against full differential with the available control pressure.

The JSA gives our service technicians a convenient procedure for reviewing the job with the rig crew, heightens the awareness of safety risks, and focuses on using the right tools for the job. An additional endurance cycles are applied to simulate 20 years of life expectancy. Our experience has demonstrated that in-house elastomer seal manufacture and optimized compounds provide the most reliable combination of mechanical and chemical properties in a premium elastomer seal. Choosing precisely the right solution for your well can reduce both drilling and completion costs.

The adapter can remain attached to the drilling riser system for subsequent wells. Lubrication of the stem bearings and occasional greasing of the valve are the only routine maintenance required. Following you will find the most generally used. Is available in various ID and OD combinations to adapt casing spools and tubing heads to different casing sizes.
