Product Overview

Core Product Models and Functions

Our lineup focuses on critical components for oilfield well control, separation systems, and rotating machinery, each designed to solve specific operational pain points. The Separator Friction TPQ330-07 30″ is a key component for oil-gas separation systems, solving the problem of unstable separation efficiency caused by worn friction parts—it ensures consistent friction force to maintain separation accuracy. The 2FZ28-35BLWS 3-1/2″ gate assembly (drawing number 2FZ2835ALWS.0 2B-00) is used in wellhead control, eliminating the risk of wellhead leakage that can lead to safety hazards and environmental contamination. The Brake Band 541 0278 for WEATHERFORD TT 5.5-15 equipment solves the issue of brake failure due to worn bands, ensuring reliable stopping power for drilling equipment. The SB68J0015 7314 ZWZ bearing (new part # 7314 AC M) prevents rotating system jitter and wear, a common problem that shortens equipment life. The Fluid end assy AH130101050100 is a core part of mud pumps, solving the pain of fluid end leakage and inefficiency, which reduces drilling productivity. Each part is manufactured to match original equipment specifications exactly, ensuring seamless replacement without modifications.

Structural Features

Every part is engineered with structural optimizations to thrive in harsh oilfield and industrial environments, with unique design features and exclusive performance data. The Separator Friction TPQ330-07 30″ is made of high-strength friction material with a steel backing, ensuring a service life of 7500 hours—1500 hours longer than standard friction parts. Its surface roughness is Ra 1.2μm, providing stable friction without damaging mating components. The 2FZ28-35BLWS gate assembly is crafted from forged alloy steel,经过 heat treatment to achieve a hardness of HRC 40-45, with a sealing surface precision of ±0.01mm to prevent leakage. The Brake Band 541 0278 uses high-temperature resistant friction material, capable of withstanding 250℃ without losing braking performance. The SB68J0015 7314 ZWZ bearing features a double-row angular contact design, with a radial load capacity of 125kN and axial load capacity of 58kN, reducing vibration to 2.1mm/s. The AH33001-05.04 cylinder liner seal uses a double-lip design with nitrile rubber material, with a maximum pressure resistance of 30MPa and a leakage rate of 0mL/h. These structural enhancements not only improve durability but also reduce maintenance frequency, saving users time and money.

Applicable Working Conditions

Our parts are specifically designed for the most demanding oilfield and industrial environments, with proven performance across extreme conditions. The 2FZ28-35BLWS gate assembly (3-1/2″) operates stably under high pressure (up to 35MPa) and high temperature (-40℃ to 120℃), suitable for onshore and offshore wellhead control. The Separator Friction TPQ330-07 30″ is ideal for oil-gas separation systems in desert and high-humidity oilfields, resisting dust and corrosion. The Brake Band 541 0278 for WEATHERFORD TT 5.5-15 works reliably under heavy load (up to 2500kg), suitable for drilling rig braking systems. The SB68J0015 7314 ZWZ bearing is compatible with rotating machinery in dusty and high-vibration environments, such as centrifugal pumps and drill pipe rotors. The Fluid end assy AH130101050100 withstands the corrosion of drilling mud, making it suitable for mud pump systems in downhole drilling operations. All parts undergo strict environmental adaptability testing, including salt spray, high-temperature, and vibration tests, ensuring stable operation in the harshest work sites.

Maintenance and Care Suggestions

Our engineers, with over 15 years of oilfield equipment maintenance experience, offer practical, easy-to-follow tips to extend part life and avoid common mistakes—tips we’ve learned from working directly with oilfield teams:

• For Gate Assemblies (2FZ28-35BLWS): Clean the sealing surface before installation, apply high-pressure grease to reduce friction. Check the gate opening and closing flexibility every 200 hours; lubricate the stem if it becomes stiff. Pitfall Reminder: Do not force the gate open or closed—this can damage the sealing surface and cause leakage, a common mistake that leads to costly repairs.

• For Separator Friction Parts (TPQ330-07 30″): Inspect the friction surface every 300 hours for wear; replace if wear exceeds 0.5mm. Keep the surface clean to avoid dust buildup, which reduces friction efficiency. Pitfall Reminder: Do not use abrasive cleaners on the friction surface—this scratches the material and shortens service life.

• For Bearings (SB68J0015 7314 ZWZ): Apply lubricating grease (NLGI Grade 2) every 500 hours; fill 1/3 of the bearing interior. Keep the bearing free from dust and moisture, as contamination causes premature wear. Pitfall Reminder: Do not heat the bearing above 100℃ during installation—this damages the internal structure and reduces load capacity.

• For Brake Bands (541 0278): Check the band tension every 400 hours; adjust if it becomes loose. Inspect for cracks or wear, replacing immediately if damage is found. Pitfall Reminder: Do not over-tighten the band—this causes excessive friction and shortens the service life of both the band and the drum.
