lWe manufacture standard structural casing head with casing hanger installed in the body. Casing hanger can be chosen as per different casing program and well conditions.
lBottom connection can be CSG,BTC,SOW or Slip-lock. We can also provide landing plate as per request. Side outlets can be threaded or studded.
lWellhead Equipment for ESP provides a tubing support and allows the power cable to pass from the surface into the well bore. The wellhead is equipped with a wellhead feed through mandrel or pack-off method. It provides a positive seal around the cable. Wellheads and cable pack-offs are available in various pressure ratings and hanging load capacities.
lWellhead:
There are two types of wellheads:
lA typical low-pressure wellhead: these type of wellheads are rated to 1500 psi but in practice should not be used once the annular pressure reaches 200 to 300 psi (13.8 to 20.7 bar). No feed-through mandrel is used. Instead, packing rubbers are packed in around the cable.
lHigh-pressure wellhead: these type of wellheads are rated at 3000 psi (206.8 bar) and have a feed-through mandrel in place of regular cable to assure a positive seal through the wellhead.
lSafety is the primary concern when selecting a wellhead. The wellhead must be pressure rated for the maximum wellhead pressure expected. For high-pressure wellheads, the amp rating of the feed thru mandrel must exceed the maximum amps expected to pass through the cable.
