2 1/2인치 유전용 스واب 컵 SV 타입 (모래 함유 유체 및 표준 스واب 맨드릴용)

Product Introduction

Optimized Fluid Lifting with 2 1/2" SV Type Swab Cups

The 2 1/2 inch SV type swab cup is a replacement component for oilfield fluid-lifting assemblies. This configuration is identified by its nominal size and flexible lip profile. For sand-laden-fluid service, match the cup dimensions and core seating to the installed tool, then specify the fluid, solids content and operating conditions for compound selection. 

Technical Specifications

Other 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. Specify bushing material, rubber compound and installation dimensions when requesting TA-style alternatives. Frac-fluid applications require the actual fluid composition and service 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.

Key Features & Advantages

1. Sand-Laden Fluid Requirements: Include particle concentration and size, tubing bore conditions and the wear pattern of the removed cup. These details help select the lip profile and compound for replacement.

2. Lip Profile Matching: Compare lip spacing and edge shape with the original cup. Supply a side-view photograph or drawing to distinguish the required SV geometry from other profiles.

3. Mandrel Installation Dimensions: Confirm core bore, cup height and shoulder seating. The nominal 2 1/2 inch designation should be used with installation dimensions to check fit.

4. Material Selection: Specify the elastomer requirement, temperature and fluid composition. Review abrasion resistance alongside compatibility and the required hardness.

5. Assembly Selection: Provide the intended fluid load and installed cup arrangement. Use the equipment operating procedure when confirming orientation and configuration.

FAQ

Question: Why is the SV style preferred for sand-laden fluids over the V style?
Answer: Select by the actual lip geometry, core configuration, compound and service conditions. Supply a worn sample or drawing and sand-content details to compare the required SV and V configurations.

Question: Can I use this 2 1/2 inch SV cup on any standard mandrel?
Answer: Confirm the core opening and seating dimensions against your mandrel drawing or measured sample before ordering. The nominal cup size alone does not establish interchangeability.

Question: How do I know if I need the HNBR material option?
Answer: Include operating temperature, pressure and complete fluid or gas composition with the inquiry. State any sour-service qualification and test requirements so the specific compound can be reviewed; the HNBR material name alone does not establish suitability.
