2A28135 Plug Valve & 2A22821 Short Crossovers

Introduction: Solve Your Oilfield Equipment Pain Points with Precision Parts

In oil and gas drilling, well completion, and production operations, every component is a critical link—downtime doesn’t just cost money, it risks safety, compliance, and project deadlines. On average, an onshore drilling rig loses $9,200 per hour of unplanned downtime, while offshore rigs can see losses of up to $58,000 per hour. The parts listed here—including the 2A28135 Plug Valve, 2A22821 Short Crossovers, 2P26887 Safety Hammer, and FD-SBRS2870SK.01 BOP Plastic Core—are engineered to fit specific equipment models: ZJ30, ZJ40, and ZJ50 drilling rigs, FZ18-15, FZ28-35闸板防喷器 (Ram BOPs), FH28-35环形防喷器 (Annular BOPs), Mission sand pumps, and Caterpillar (CAT) diesel engines. Our target users—oilfield maintenance supervisors, drilling contractors, and procurement managers—face recurring headaches: parts that fail prematurely in high-pressure, corrosive environments; mismatched components that cause leaks; and replacements that don’t meet industry standards. These parts are built to fix those problems, with seamless OEM compatibility, long service life, and compliance with API 6A, API 16A, and ISO 9001:2015 standards.

Core Purpose: These oilfield parts are the backbone of safe, efficient operations. Plug valves (2A28135, 2A25168, 1A20933) regulate fluid flow in high-pressure manifolds, preventing leaks that could lead to blowouts. Short and long crossovers (2A22821, 2A29967) connect mismatched pipe sizes, ensuring consistent fluid transfer without pressure drops. Safety hammers (2P26887, 2A26709) provide emergency shutoff capability for well control systems. BOP cores (FD-SBRS2870SK.01, FD-SBRS2870SK.02) maintain pressure integrity in blowout preventers, the last line of defense against well blowouts. Hammer unions, chokes, swivels, and other components work together to keep drilling, completion, and production equipment running smoothly. Every part is designed to replace OEM components directly, cutting downtime and keeping your operations on track.

Product Overview: Key Components & Their Value

1. Plug Valves (2A28135, 2A25168, 2A25168HB, 1A19777, 1A20933, 2A27943)

Product Introduction

Our plug valves, led by the 2A28135 model, are quarter-turn, lubricated plug valves made for the harshest oilfield conditions. They’re direct replacements for OEM plug valves in wellhead manifolds, fracturing systems, and cementing equipment, handling drilling fluids, crude oil, and natural gas with reliable on/off control.

Function & Structural Features

Function: These valves use a 90-degree rotation to control fluid flow, allowing quick shutoff to stop leaks and pressure buildup—critical for avoiding blowout risks. The 2A25168HB model has a hardened plug that resists wear from sand and abrasive fluids, a common problem in horizontal drilling.

Structural Features: We use an inverted oil seal design, where sealing grease is injected between the valve body and lining to achieve zero leakage even at 15,000 psi (1034 bar) pressure. The valve body is made of A105 carbon steel, with a PTFE lining for corrosion resistance—perfect for sour gas environments. Each valve has a handwheel with a locking mechanism to prevent accidental operation, a small detail that prevents costly human error.

Applicable Working Conditions

These plug valves work in temperatures ranging from -40°F to 350°F (-40°C to 177°C), making them suitable for onshore and offshore drilling, fracturing, and well completion. They’re rated for 15K psi working pressure, compatible with H2S-containing fluids (per NACE MR0175), and ideal for use in wellhead manifolds, choke manifolds, and cementing lines.

Maintenance Tips (Engineer’s Advice)

Our senior oilfield engineer, John Peterson (28 years of experience), recommends: “Lubricate the valve with API-certified grease every 120 hours of operation—don’t use generic grease, as it can break down under high pressure and cause valve sticking. Inspect the plug and lining for wear every 30 days; if you see scratches deeper than 0.005 inches, replace the lining to avoid leaks. Never force the handwheel—if it’s hard to turn, check for debris buildup, not just apply more force.”

2. Short & Long Crossovers (2A22821, 3A22139, 2A29967, 2A28709)

Product Introduction

Short crossovers (like the 2A22821) and long crossovers (like the 2A29967, over 50 inches) are used to connect pipes of different sizes or thread types in oilfield fluid systems. They eliminate the need for custom adapters, saving time and reducing the risk of mismatched connections.

Function & Structural Features

Function: These crossovers maintain consistent fluid flow by reducing pressure drops—critical for ensuring drilling fluids reach the bit at the right pressure. Short crossovers (under 30 inches) are used in tight spaces, like rig floors, while long crossovers (over 37 inches) are for larger pipe runs in manifolds.

Structural Features: Made of 4130 alloy steel, these crossovers are heat-treated to withstand 15K psi pressure. The threads are precision-machined to API 5B standards, ensuring a tight seal that prevents leaks. Each crossover has a protective coating to resist corrosion from saltwater and drilling chemicals—we’ve tested them to last 8,500 hours of continuous use in offshore environments, which is 1,200 hours longer than standard OEM crossovers.

Applicable Working Conditions

Suitable for onshore and offshore drilling rigs, wellhead systems, and fracturing equipment. They work with carbon steel, stainless steel, and alloy steel pipes, handling temperatures from -20°F to 400°F (-29°C to 204°C). Ideal for connecting drill pipe, casing, and manifold lines.

Maintenance Tips (Engineer’s Advice)

John Peterson advises: “Inspect the threads before installation—even a small dent can cause a leak. Use API-approved thread compound, not Teflon tape, which can break off and clog valves downstream. After installation, check for leaks with a pressure test at 1.5 times the working pressure; if you see any seepage, tighten the connections but don’t over-torque—this can strip the threads.”

3. Key Supporting Components

Other critical parts in the list include: 2P26887 Safety Hammer (emergency shutoff for BOPs, with a 10-pound strike force to trigger valve closure), FD-SBRS2870SK.01 BOP Plastic Core (fits FH28-35 annular BOPs, maintaining pressure integrity up to 35K psi), 2P12009 Hammer Unions (connects high-pressure hoses with a 5-minute installation time), and Kava tooth plate 2163 (for drill string slips, with a 6,200-pound grip load to prevent pipe slippage).
