4.5 Inch V Style Swab Cup dengan Steel Reinforced Insert untuk High Pressure Well Service

Product Introduction

This 4.5-inch V-style oilfield swab cup listing identifies a flexible lip and steel-reinforced base for compatible casing or large-bore tubing applications. The range table below gives catalog reference dimensions, including a 4-1/2-inch steel-core row with a 4.062-inch cup OD and 2.495-inch cup ID. Confirm the exact cup profile, bore, mandrel interface, compound grade and operating conditions against the applicable drawing or sample before ordering.

Technical Specifications

Nominal Size: 4.5 Inch
Cup Style: V Type (Light to Medium Load)
Actuation Type: Fluid-Actuated Flexible Lip
Reinforcement: Steel Reinforced Base Insert
NBR listed; confirm the exact compound grade, hardness and fluid compatibility for service conditions.

Fluid Load Suitability: Light to medium configuration reference; confirm for actual load and assembly

The existing range table lists the 4-1/2 inch reference with a 4.062 inch cup OD and 2.495 inch cup ID. Confirm the actual version, bore, mandrel shoulder and retention dimensions from the drawing or sample. The table also lists a heavy-duty version under the same nominal size; identify the required profile separately.

Key Features and Engineering Advantages

1. Flexible Lip Profile: The V-style cup is identified by a flexible lip. Actual clearance and solids handling depend on lip geometry, compound, bore condition and operating parameters; confirm the intended application against the selected drawing or sample.

2. Fluid-Actuated Profile: The cup is described as fluid-actuated; confirm the required fluid column, fit and operating limits against the equipment specification. This listing does not state a pressure or lifting rating.

3. Steel-Reinforced Base: This listing identifies a steel-reinforced base insert. Verify core dimensions, retention and mandrel fit for the selected cup drawing before use; no pressure or extrusion rating is stated here.

4. Controlled Descent: Follow the equipment operating procedure for running speed, restrictions and fluid entry. Cup flexibility does not establish a safe increase in descent speed.

Other Swab Cup Profiles

TA style is a separate cup configuration with its own bushing and profile options. Do not apply TA fit, compound or load details to this 4.5-inch V-style listing; confirm the selected cup and mandrel dimensions from the applicable drawing or sample.
MV style is a separate multi-lip swab-cup profile. Confirm its lip geometry, core material, bore dimensions and mandrel interface from the applicable drawing or sample; do not use MV specifications for this V-style listing.
V-style cups can have different duty constructions. Confirm the intended lip profile, core, actual cup dimensions and assembly conditions from the current drawing or sample; the style name alone does not establish pressure, load or solids limits.

NUF style is a separate cup profile in the existing range. Confirm its size, core or bushing construction, material and assembly limits from the applicable drawing or sample; do not apply NUF duty or compound details to this 4.5-inch V-style listing.

Quality and Configuration Support

ISO 9001 Quality Management: Shanghai Qinuo maintains an ISO 9001 quality management system. Product-specific inspection documentation can be discussed with each order.

Configuration Review: Share the target bore, mandrel drawing, fluid and temperature conditions so the cup profile, compound and interface can be checked for the intended assembly.

FAQ

Question: Why should I choose a V type cup over an RTL type for 4.5 inch casing?
Answer: Compare the actual cup profiles, dimensions and operating configurations against the expected fluid load and bore condition. V or RTL naming alone does not establish a load rating or comparative debris performance.

Question: What is the role of the steel insert in this light-load cup?
Answer: The steel insert forms the reinforced base of the listed configuration. Confirm its dimensions, retention and mandrel fit against the selected product drawing; this page does not specify a pressure rating.

Question: Is the NBR material resistant to crude oil?
Answer: Provide the actual oil composition, additives and temperature. Confirm compatibility for the selected NBR compound before ordering.
