RTL タイプ 2.5インチ スワブカップ 中程度のウェル負荷に最適化

Product Introduction

This 2-1/2-inch RTL type oilfield swab cup is listed for medium-to-light-load swabbing assemblies. Its dual-lip profile and metal core define this configuration; compare cup outside diameter, core opening and seating dimensions with the tubing and mandrel drawing before ordering. The listing identifies nitrile rubber (NBR) with a hardness range of 80 to 90 Shore A. Confirm the selected compound and dimensions against the well fluids and planned operating conditions.

Technical Specifications

	Material:	Nitrile rubber (NBR)
	Size:	2 1/2 Inch
	Style:	RTL
	Hardness:	80 to 90 Shore A

Operational Field Guidelines

Stacking: Set cup count and orientation from the tool drawing and the approved operating procedure. Include the cup position, mandrel configuration and service conditions when requesting a replacement.

Mandrel fit: A nominal 2-1/2-inch size alone does not confirm compatibility. Compare the cup outside diameter and lip interference, core opening and seating shoulders with the tubing and mandrel drawing or an existing sample.

Operating procedure: Follow the approved wireline program for descent and retrieval. Set speed and fluid-column limits from the tool design and job conditions; inspect the lips and core seating before assembly.

Storage and inspection: Follow the supplier storage guidance, protect elastomer parts from heat, sunlight and ozone, and inspect the lips and core before use.

Key Features and Benefits

1. RTL dual-lip profile: This cup uses two lips as part of its sealing geometry. Sealing behavior depends on cup dimensions, tubing bore, fluid column, wear and well conditions; lip count alone does not establish recovery performance.

2. Medium-to-light load listing: This product is positioned for medium-to-light-load swabbing. Confirm the fluid column, cup arrangement and tool-string limits for the planned run.

3. NBR material: Nitrile rubber is identified for this listing. Confirm the selected compound grade, hardness, temperature and fluid-additive compatibility for the service.

4. Tubing fit: Verify the measured tubing inside diameter, cup outside diameter and required lip interference against the product drawing or sample; nominal size does not establish fit.

5. Metal core and mandrel seat: Compare the core opening, retaining shoulder and seating dimensions with the specific mandrel drawing or sample.

Frequently Asked Questions

Question: What does the dual-lip RTL profile identify?
Answer: The listing identifies a two-lip RTL profile. Sealing behavior depends on dimensions, tubing condition, fluid column and operating conditions; lip count alone does not establish recovery performance.

Question: What information is needed to assess sand service?
Answer: Suitability depends on sand concentration, particle size, clearances and run conditions. Provide those details and the tool drawing when comparing cup styles.

Question: Will a 2-1/2-inch cup fit every 2-1/2-inch tubing or casing?
Answer: Nominal size alone does not confirm fit. Check the actual tubing or casing inside diameter, cup outside diameter, lip interference and core-to-mandrel dimensions.

Question: How should NBR compatibility with well fluids be checked?
Answer: Review the selected NBR compound grade against the exact fluid, additives, temperature and exposure conditions before use.
