Product Overview
Double ram side door stripper is heavy-duty high-pressure well control stripping box specially designed for coiled tubing operation trucks targeting deep, high-pressure and sour oil & gas wells. Equipped with two independent hydraulic sealing rams, it forms double pressure barrier protection to eliminate blowout risks during CT running and pulling. The split side door structure enables quick replacement of rubber packers without retrieving coiled tubing. Rated working pressure reaches 15,000 PSI with 22,500 PSI factory test pressure. All fluid-wetted metal components meet NACE MR-01-75 hydrogen sulfide resistance standard for harsh corrosive well conditions.
Key Features
- Dual Ram Redundant Sealing System – Two separate hydraulic rams with independent opening & closing control. One ram acts as backup sealing if the other packer wears or leaks, maximum safety for high-risk wells.
- Side Door Fast Maintenance – Split side door allows on-site seal replacement while coiled tubing remains in the well, greatly reduces operation downtime and service cost.
- 15,000PSI Ultra High Pressure Rating – Nominal working pressure 15,000 PSI, hydrostatic test pressure up to 22,500 PSI, compliant with API high-pressure well control standards.
- Universal Coiled Tubing Matching – Supports CT outer diameter: 1.5", 1.75", 2", 2.375", fits all mainstream coiled tubing sizes for onshore & offshore CT units.
- NACE MR-01-75 Anti-Sulfur Corrosion – All metal parts contacting well fluid adopt anti-H₂S treatment, stable service in high-sulfur oil & gas fields.
- CO56 Male Union Bottom Connection – Standard CO56 male union interface for fast, tight connection with coiled tubing BOP stack and lubricator accessories.

FAQ
Q1: What is the difference between double ram and single ram side door stripper?
A: Double ram stripper has two independent sealing assemblies to provide redundant pressure barriers, which is safer for high-pressure, high-sulfur risky wells compared with single ram models.
Q2: What is the maximum working pressure of this double ram stripper?
A: Rated working pressure is 15,000 PSI, hydrostatic test pressure is 22,500 PSI.
Q3: Can I replace rubber packers without pulling coiled tubing out?
A: Yes, unique side door split design supports on-site seal replacement with coiled tubing staying inside the well.
Q4: Does this stripper work for H₂S containing sour wells?
A: All fluid contact metal components comply with NACE MR-01-75 standard for sour service.
