Shaffer Ram BOP 13 5/8"-10000psi Forging Type

The Shaffer Ram Blowout Preventer (Ram BOP) is essential well control equipment for oil and gas drilling, workover, and well testing operations. It precisely controls wellbore pressure, prevents blowout accidents, and provides comprehensive safety guarantees for downhole operations while adapting to various complex working conditions.

Core Features

Solid Structure & Corrosion Resistance: Main pressure-containing components (body, bonnet, ram block) are manufactured from high-strength, high-toughness alloy steel through casting and forging processes, reinforced by heat treatment. Complies with API Spec 16A and NACE MR 0175/ISO 15156 standards with specialized anti-corrosion treatments for harsh downhole environments.
Wide Range of Bore Sizes & Pressure Ratings: Available in bore sizes including 7 1/16", 9", 11", 13 5/8", 16 3/4", 21 1/4", and 26 3/4". Rated working pressure ranges from 2000psi (13.8MPa) to 15000psi (103.4MPa) for medium-high to high-pressure operation scenarios.
Reliable Ram Performance: Features HF-type forged rams (recommended) and S-type split rams. Available in pipe rams, blind rams, shear rams, and variable-bore rams for annular space sealing, full wellbore sealing, and emergency string shearing functions.
Dual Protection Sealing System: Initial sealing through four key points plus well pressure-assisted sealing. Equipped with secondary sealing mechanism for emergency remediation via grease injection if primary seals are damaged.
Structure Designed for Easy Maintenance: High support ribs and sand-settling inclined surface reduce friction. Internal buried hydraulic oil circuit prevents damage. Hinged bonnet design facilitates disassembly and maintenance.
Flexible & Safe Operation Modes: Supports hydraulic control and manual locking. Hydraulic operation completes ram opening/closing in 3-15 seconds. Manual locking secures ram position during long-term well sealing without continuous hydraulic pressure.

Opening Methods & Bonnet Design

Hydraulic Direct Opening

Inject high-pressure oil (8.4-10.5MPa) into the ram opening cavity to push the piston, driving the ram shaft and ram assembly away from the wellhead center.

Hydraulic Opening After Manual Unlocking

First rotate the handwheel counterclockwise to drive the locking shaft to the end, then turn back 1/8-1/4 turn before supplying pressure to the opening cavity.

Hinged Bonnet Opening

Bonnet connects to body through hinge base assembly. Loosen bonnet bolts and rotate bonnet for ram assembly removal and maintenance.

Wellhead Installation & Inspection

Pre-Installation Inspection

Check flange sealing gasket ring grooves and surfaces for defects
Confirm ram specifications match downhole drilling tool size
Verify BOP has passed pressure testing and is qualified

Wellhead Installation Steps

Apply ISO 13678 compliant thread grease and tighten bolts diagonally in three stages
Connect hydraulic control pipelines according to opening/closing marks
Connect manual operating lever and verify locking mechanism operation

Post-Installation Inspection

Confirm correct BOP installation with body lifting lugs at top
Test open/close each ram type twice with 2-3MPa control pressure
Check manual locking mechanism flexibility and mark handwheel rotations
Verify kill and choke manifold connections and conduct comprehensive pressure test

Usage Methods

Specialized Operation: Assign dedicated personnel with comprehensive training in BOP operation and maintenance
Standardized Operating Pressure: Maximum 3MPa for pipe ram testing without string; never close blind or shear rams with string present
Use of Manual Locking: For long-term well sealing, close ram hydraulically first, then engage manual locking with warning tags
Regular Inspection & Maintenance: Daily ram operation checks in target zones, blind ram testing after tripping operations, and regular performance testing
Timely Fault Handling: Relieve pressure before troubleshooting issues like incomplete ram operation or sealing leakage
