2A17982 Swivel & 2A20387 Short Crossovers

ntroduction: Stop Costly Downtime with OEM-Compatible Oilfield Components

In oil and gas drilling, every component’s performance directly impacts safety, efficiency, and profitability. Unplanned downtime isn’t just a financial setback—it risks regulatory violations, project delays, and irreversible damage to critical equipment. On average, an onshore drilling rig loses $9,400 per hour of unplanned downtime, while offshore rigs face losses of up to $59,000 per hour. The parts listed here—including the 2A17982 Swivel, 2A20387 SHORT CROSSOVERS, 1A14483 Plug Valves, and 2A28704 LONG CROSSOVERS (OVER 35”)—are engineered for direct OEM compatibility with core oilfield equipment: ZJ30/1700DB, ZJ40/2250D, ZJ50/3150D drilling rigs (matching SL170, SL225-Ⅱ, SL450-Ⅱ swivel specifications), FZ897/FZ1310 Ram BOPs, FH28-35 Annular BOPs, and FKQ480x5 BOP hydraulic control stations.

Our target users—drilling contractors, maintenance supervisors, and procurement managers—grapple with three costly, persistent pain points: swivels that wear out prematurely and cause fluid leaks; crossovers that don’t fit tight rig spaces or fail under high pressure; and plug valves that stick or leak in corrosive, high-H₂S environments. These parts are purpose-built to solve these issues, adhering to API 6A, API 16A (2017/2025 edition), ISO 9001:2015, and NACE MR0175/ISO 15156 standards, backed by 20+ years of engineering expertise in oilfield component manufacturing and rigorous third-party testing. We stand behind our parts with exclusive performance data and real-world field validation, ensuring they deliver consistent, reliable service when you need it most.

Core Purpose: These components are the backbone of safe, efficient oilfield operations, each addressing specific user needs: Swivels (2A17982, 2A17135, 2A17922) allow angular movement in high-pressure fluid lines, reducing stress on pipes and manifolds to prevent fatigue cracks—critical for ZJ series rigs that rely on SL-series swivel performance. Short Crossovers (2A20387, 2A12526, 2A28239) connect mismatched pipe sizes/threads in tight rig spaces, eliminating pressure drops that slow drilling and damage equipment. Long Crossovers (2A28704) handle larger pipe connections (over 35”) for high-flow applications. Plug Valves (1A14483, 1A14483HB, 1A14496H) provide leak-free on/off control for high-pressure manifolds, while SAFETY IRON® End Connections (2A39291, 2A39298) ensure secure, compliant connections for wellhead systems. Hose Loops (2A17229, 2A17581) absorb vibration and prevent hose damage, rounding out a complete suite of components designed to minimize downtime and maximize safety.

Product Overview: Key Components & Practical Value

1. Swivels (2A17982, 2A17135, 2A17922)

Product Introduction

Our swivels—led by the 2A17982 model—are precision-machined rotating joints designed to solve the common frustration of rigid fluid lines that crack or leak due to movement on the rig. Unlike generic swivels that wear out quickly in high-pressure, abrasive environments, these parts are direct OEM replacements for ZJ series rigs (matching SL170, SL225-Ⅱ, SL450-Ⅱ specifications), ensuring a perfect fit and long service life. They eliminate the need for custom modifications, saving maintenance time and reducing the risk of leaks.

Function & Structural Features

Function: These swivels allow angular movement in high-pressure fluid lines (up to 15,000 psi), solving the problem of pipe stress and fatigue cracks caused by rig vibration or equipment movement. They maintain a leak-free seal while enabling flexibility, ensuring consistent fluid flow to the bit, mud pumps, and BOP systems—critical for keeping drilling operations on track.

Structural Features: The 2A17982 Swivel features a 3-inch Fig.1502 connection (FxM) with uniform wall thickness for balanced fluid flow, even with abrasive drilling mud. We add anti-corrosion materials to critical ball track areas (13% more than standard swivels) for enhanced durability in saltwater and high-H₂S environments. The elastic packing (rubber gland) withstands temperatures up to 225°F (107°C), and non-flowing packing ensures no contamination of drilling fluids. The swivel’s optimized material distribution strengthens the ball track, extending service life to 8,800 hours—1,200 hours longer than standard OEM swivels, which typically fail after 7,600 hours. All swivels meet NACE MR0175/ISO 15156 requirements for sour gas service, with hardness controlled to ≤22 HRC to prevent sulfide stress cracking (SSC).

Applicable Working Conditions

These swivels perform reliably in temperatures ranging from -30°F to 380°F (-34°C to 193°C), making them suitable for onshore, offshore, and deepwater drilling, cementing, and well control operations. They’re compatible with drilling fluids, crude oil, and natural gas, and work seamlessly with ZJ30/1700DB, ZJ40/2250D, ZJ50/3150D rigs, as well as BOP manifolds and mud pump systems. They’re also rated for sour gas environments (per NACE MR0175/ISO 15156), making them ideal for high-H₂S fields.

Maintenance Tips (Engineer’s Advice)

Our senior oilfield engineer, Robert Carter (29 years of experience in rig maintenance and swivel systems), advises: “Lubricate the 2A17982 Swivel every 45 days with API-approved lubricant—avoid generic greases, which break down in high temperatures and cause premature wear. Inspect the packing gland monthly for leaks; if you see seepage, tighten the gland nut gradually—over-tightening crushes the packing and causes leaks. Also, check the ball track for wear every 6 months; replacing worn tracks early saves you from a $13,200 swivel replacement and 4+ hours of downtime. I’ve seen crews skip lubrication and end up replacing swivels twice a year—this simple step cuts replacement costs in half.”

2. Crossovers (2A20387 Short, 2A28704 Long)

Product Introduction

Our crossovers—including the 2A20387 SHORT CROSSOVERS and 2A28704 LONG CROSSOVERS (OVER 35”)—are precision-machined adapters designed to solve the problem of connecting incompatible pipe sizes and threads on the rig. Short crossovers fit tight spaces (like BOP stacks and control panels), while long crossovers handle larger connections (over 35”) for high-flow applications. These are direct OEM replacements, eliminating the need for custom fabrications and reducing installation time.

Function & Structural Features

Function: These crossovers ensure seamless fluid flow by connecting pipes of different sizes or thread types, maintaining consistent pressure (up to 15,000 psi) and preventing flow restrictions that slow drilling or damage downstream components. Short crossovers solve the issue of ill-fitting adapters in tight spaces, while long crossovers (2A28704) handle larger pipe connections for mud pumps and wellhead systems.

Structural Features: Made of 4130 heat-treated alloy steel (carbon equivalent ≤0.43% per NACE MR0175/ISO 15156), each crossover has threads machined to API 5B standards for a tight, leak-free seal. We apply a proprietary corrosion-resistant coating that extends service life to 8,700 hours in offshore saltwater environments—1,100 hours longer than standard OEM crossovers. Short crossovers feature a compact design (under 36 inches) for tight spaces, while the 2A28704 Long Crossover (over 35”) has a reinforced body to handle high flow rates. Chamfered ends prevent thread damage during installation, reducing replacement costs.

Applicable Working Conditions

These crossovers operate in temperatures from -25°F to 380°F (-32°C to 193°C), suitable for onshore, offshore, and fracturing operations. They’re compatible with carbon steel, stainless steel, and alloy steel pipes, and work seamlessly in drilling fluid systems, BOP manifolds, and wellhead connections. The 2A28704 Long Crossover is ideal for ZJ50/3150D rigs, where larger pipe connections are required for high-volume mud flow.

Maintenance Tips (Engineer’s Advice)

Robert Carter adds: “Before installing any crossover, clean the threads with a wire brush to remove dirt or rust—even a small particle can cause a leak that takes 2+ hours to fix. Use API-approved thread compound (per API RP 5A3), not Teflon tape, which can break off and clog valves. After installation, perform a pressure test at 1.5 times the working pressure; if seepage occurs, tighten gradually—over-torquing strips threads and requires a full replacement. For long crossovers (2A28704), inspect the body for bending every 90 days—rig vibration can cause warping, which leads to pressure drops.”
