4.5 Inch V Style Swab Cup with Steel Reinforced Insert for High Pressure Well Servicing

Product Introduction

The 4.5 inch V Style Swab Cup is a versatile and highly flexible tool designed for light to medium load fluid recovery in casing and large bore tubing. Known for its fluid-actuated design, the V style cup features a responsive sealing lip that expands under minimal hydrostatic pressure. This model is specifically engineered for wells containing sand, silt, or other suspended solids, as its flexible profile can effectively bypass debris during the run while maintaining a consistent seal during the lift. The integrated steel reinforced insert provides the necessary base stability required for 4.5 inch diameters without compromising the lip flexibility.

Actuation Type: Fluid-Actuated Flexible Lip
Reinforcement: Steel Reinforced Base Insert
Material: Premium Abrasion Resistant Nitrile (NBR)
Fluid Load Suitability: Light to Medium

Key Features and Engineering Advantages

1. Superior Sand and Debris Tolerance: The thin, flexible lip of the V style cup is exceptionally effective in sand-laden fluids. It allows the cup to navigate past particulates and scale buildup that might damage more rigid, heavy-load cups.

2. Fluid Actuated Sealing: The V-shaped geometry ensures that the sealing lip is forced against the casing wall by the weight of the fluid column. This design allows for a positive seal even with lower fluid levels or lighter loads.

3. Steel Insert for Base Stability: In the 4.5 inch size, the steel insert is critical for maintaining the structural integrity of the cup base on the mandrel, preventing extrusion while allowing the upper lip to remain highly flexible.

4. Ease of Descent: Due to its flexible profile, the V type cup experiences less resistance during descent, allowing for faster trip times in well servicing operations.

All Available types of Swab cups

TA style: TA is a medium load Swab Cup built around a steel or aluminum bushing for use in most sizes of tubing or drill pipe. When under load, it will compress to form a solid rubber mass for maximum lifting capacity and minimum wear. Manufactured from a newly developed rubber compound, these cups provide our customers with a high quality North American product. Our special Frac Fluid compound is developed for the ultimate in durability and performance. These Frac Swab Cups are designed to perform under the toughest conditions.

MV style: Shanghai Qinuo offers the popular Guiberson* profile MV Swab Cup in both nitrile and frac fluid rubber compound. The cup has either an aluminum or steel bushing with multiple upturned lips which allows it to pass through tight spots and control the amount of load. It is very efficient in fluid with suspended sand.

V style: Shanghai Qinuo carries the V Series Swab Cup in a light duty and heavy duty all rubber cup that is suited for use in fluids with high concentrations of suspended sand. The upturned lips pass easily through tight spots and will invert to dump excessive loads. The number of cups used will vary with conditions.

FAQ

Question: Why should I choose a V type cup over an RTL type for 4.5 inch casing?
Answer: Choose the V type if you are dealing with light fluid loads or if the wellbore contains sand and debris. The RTL is a heavy-load cup with a rigid lip, whereas the V type is designed for flexibility and debris tolerance.

Question: What is the role of the steel insert in this light-load cup?
Answer: The steel insert provides a rigid foundation for the cup base. In larger 4.5 inch sizes, this reinforcement is necessary to keep the cup secured on the mandrel shoulder under hydrostatic pressure.

Question: Is the NBR material resistant to crude oil?
Answer: Yes, the high-grade Nitrile (NBR) compound is specifically formulated for excellent resistance to crude oil, diesel, and most oilfield hydrocarbons.
