SW-22 Series & TD Series Drilling Seal Spare Parts

Core Purpose & Target User Orientation

This complete line of SW-22 series and TD series drilling sealing spare parts is specially engineered to fit API 8A/API RP 7L certified land and offshore top drive drilling systems, workover rigs, and rotary drilling equipment covering medium to heavy load drilling operations. It caters to refined user demands including oilfield rig maintenance engineers, drilling equipment procurement specialists, offshore platform maintenance teams, and oilfield spare parts stocking departments that prioritize zero leakage, long service life, fast on-site replacement, and consistent part compatibility. The core purpose of this product line is to eliminate high-pressure drilling fluid leakage, reduce frequent part wear and tear, cut down rig downtime caused by sealing failures, and solve the hassle of mismatched aftermarket parts in harsh drilling environments. Every component is built to serve as a direct, reliable replacement for original equipment parts, supporting daily rig maintenance, emergency fault repair, and long-term spare parts inventory planning for drilling teams worldwide.

Product Introduction

We specialize in the production and supply of full-specification SW-22 series and TD series drilling sealing spare parts, covering cartridge assemblies, washpipe assemblies, packing kits, adapter rings, grease fittings, nuts, snap rings, and various spacer components. All parts are manufactured in full compliance with API international industry standards and original equipment dimensional specifications, with 100% interchangeability with branded drilling equipment, no on-site modification required for installation.

Backed by 20+ years of oilfield sealing component manufacturing experience and a full-process quality control system, each part undergoes three rounds of high-pressure sealing testing, wear resistance testing, and corrosion resistance testing before leaving the factory. Our exclusive internal testing data shows that core components such as SW-22-030-012 cartridge assembly and TD-30123290 cartridge assembly deliver a continuous safe service life of 1750 drilling hours under rated working pressure; washpipe assemblies maintain surface integrity without deep scratches after 1400 hours of reciprocating operation. We hold formal API quality certification and material performance testing reports, ensuring every batch of products meets oilfield industrial operation standards, making this product line a trusted choice for both routine maintenance and critical drilling sealing solutions.

Functional Description

1. High-Pressure Dynamic Sealing: Blocks high-pressure drilling mud and fluid leakage during top drive reciprocating and rotating operation, stably maintaining sealing performance under 4500-7000 PSI working pressure, completely eradicating safety risks and equipment corrosion caused by fluid leakage.

2. Wear & Corrosion Resistance: Resists erosion from sand particles in drilling fluid and chemical corrosion from drilling additives, slowing down part wear and extending replacement cycles to reduce frequent maintenance workload.

3. Quick On-Site Replacement: Standardized dimensional design and modular structure allow maintenance teams to replace damaged parts without dismantling the entire drilling power assembly, shortening maintenance duration and reducing labor input.

4. Stable Pressure Distribution: Matching spacer rings and adapter rings evenly distribute internal pressure of the sealing system, preventing local overpressure that leads to premature packing failure and keeping the entire sealing system running steadily.

5. Regular Lubrication Support: Specialized grease fittings provide smooth lubrication access for sealing pairs, reducing friction between moving parts and further prolonging the service life of core sealing components.

Structural Features

This product line adopts a layered, modular sealing structure tailored for heavy-duty drilling scenarios. The precision-machined cartridge assemblies (SW-22-030-012, SW-22-035-012, TD-30123290, TD-8021) feature integrated pre-assembly design, eliminating on-site assembly errors and ensuring consistent sealing performance. Washpipe assemblies with snap rings (SW-70-109-16, SW-70-109-18, TD-30123289) use smooth precision-ground surfaces to minimize packing wear, with snap rings for firm positioning to avoid part displacement under rig vibration. Multi-specification packing rings and packing housings form a multi-layer sealing barrier, while upper, middle, and lower spacers (TD-123285, TD-30123286, TD-30123287) realize precise pressure splitting. All adapter rings, retaining rings, and lock nuts adopt anti-loosening structural design, tightly fitting the sealing system and preventing part loosening under long-term high-frequency vibration.

Applicable Working Conditions

These spare parts are suitable for land deep-well drilling, shallow well workover, offshore platform drilling, and desert oilfield drilling operations, adapting to an ambient temperature range of -25℃ to 115℃. They perform stably under high-sand content drilling fluid, high-corrosion drilling medium, and continuous heavy-load operation conditions, compatible with medium and large-tonnage top drive drilling equipment matching SW-22 series and TD series models. The product line supports both new equipment assembly and old equipment aging part replacement, fully meeting the harsh operation requirements of global mainstream oilfield drilling rigs.

Maintenance & Engineer Operation Suggestions

1. Routine Inspection: Check sealing surfaces for leakage, grease fitting blockage, and snap ring looseness every 180 drilling hours; record wear degree of washpipe surfaces and packing rings to plan part replacement in advance.

2. Lubrication Rules: Use special high-temperature anti-wear drilling grease for regular lubrication, never mix different types of grease to avoid rubber sealing part aging and deterioration.

3. Installation Avoidance Tips: Keep all mating interfaces clean and free of sand impurities during installation; tighten ring nuts and lock nuts in a crosswise, uniform manner, do not use excessive torque which will crush packing rings or cause insufficient sealing due to uneven pressure. Never use brute force to knock precision parts during disassembly and assembly.

4. Stocking Reminder: Prepare vulnerable parts such as washpipe packing, O-rings, and snap rings in advance for emergency repairs, avoiding rig shutdown caused by missing spare parts.
