The Model E-4™ wireline pressure setting assembly (WLPSA™) sets bridge plugs, cement retainers, and production packers on electric wireline. It's used with a casing collar locator for correlation of exact setting depth. The Model E-4 WLPSA is a gas-generating tool for the gradual development of hydraulic force required to set wireline deployed tools. Gas pressure is obtained by the electrical ignition of a BP-3S™ igniter that activates the secondary igniter and the power charge.
The Model E-4 WLPSA incorporates a disk bleeder valve to ensure safe and simple pressure bleed-off prior to disassembly after being run. The firing head connects the Model E-4 WLPSA to the collar locator on the electric wireline, providing electrical ignition of the powder charge through the primary and secondary igniters. The top end is blank, so threads can be machined to fit the electric wireline provider's collar locator. The firing head is available separately.
Our Model E-4 HP/HT wireline pressure setting assembly (WLPSA) is used for the gradual development of force through pressure, which operates the WLPSA in proper sequence. This ensures successful setting of bridge plugs, retainer production packers, cement retainers, and other tools deployed on wireline. It has a temperature rating of 450 deg. F [232 deg. C] and a pressure rating of 25,000 psi.
Sold in packs of 20, listed price is for a single igniter.
Baker Hughes igniters are used in conjunction with power charges to provide an economical power source for our E-4 wireline pressure setting assemblies (W.L.P.S.A.). A BP-3S™ Igniter, (Product Family No. H43744) will fire when a sufficient electrical current is passed through it. The Secondary Igniter, (Product Family No. H43743) is ignited when the Igniter fires and is blown down on top of the power charge. As the secondary burns, it provides heat input to light the power charge. The BP-5S™ Igniters are almost identical to the BP-3S except that they contain a resistor which requires a higher electrical voltage to establish a current sufficient to fire the Igniter. The BP-5S has a crimped design. The BP-5S are slightly longer for identification purposes.
The secondary igniter is used in all sizes of the E-4 and the 05 E-5 setting tools.
All Power Charges and Igniters should be stored in a cool, dry place. Exposure to excessive heat will reduce shelf life and should be avoided. Exposure to moisture will degrade the performance of Power Charges and Igniters. Do not use Primary or Secondary Igniters that have been opened for extended periods.
