Product Description
Premium slips, also known as liner hanger gripping slips or heavy-duty anchoring slips, are critical components used in hydraulic liner hanger systems. They are designed to grip the casing wall after setting and provide reliable support for the liner string during well completion operations.
In complex wellbores, slip performance directly affects liner hanger reliability. The two most common risks are premature setting before reaching the planned depth and tooth blunting or damage during running. If the slips contact tight spots, casing deformation, doglegs, or restricted sections too early, they may set prematurely or lose gripping strength. This can lead to liner running failure, poor anchoring, cementing problems, or costly downhole intervention.
Our premium liner hanger slips use a protected slip structure to help reduce unwanted casing contact while running into the well. This helps lower the risk of premature setting in tight spots and improves downhole running reliability before the hanger reaches the target setting depth.
For stronger anchoring performance, the slip teeth can be carburized or case-hardened to improve surface hardness, wear resistance, and gripping ability on P-110 and higher-grade casing applications. The slips can be customized according to tool model, casing size, liner size, material requirement, anchoring profile, and customer drawings.
What Problem Does It Solve?
| Field Problem | How Premium Slips Help |
|---|---|
| Premature setting before reaching target depth | Protected slip structure helps reduce unwanted casing contact |
| Tight spots, doglegs or casing deformation | Protected design improves running reliability in complex well sections |
| Tooth blunting during running | Carburized / case-hardened teeth improve wear resistance |
| Weak anchoring after setting | Heavy-duty gripping profile improves casing wall engagement |
| Long liner string requires high hanging capacity | Large slip design supports reliable liner suspension |
| Need replacement slips for existing tools | Custom manufacturing available according to drawings or samples |
| Sour service or corrosive well conditions | AISI 4130 / 4140 H2S-resistant alloy steel options available |

Product Features & Benefits
Protected Slip Design to Prevent Premature Setting
The protected slip structure helps reduce the risk of premature setting when passing through tight spots, casing deformation, doglegs, or complex well sections. This improves running reliability before the hanger reaches the planned setting depth.
Carburized / Case-Hardened Teeth for Stronger Grip
Carburized or case-hardened slip teeth provide higher surface hardness and better wear resistance. This helps prevent tooth blunting during running and ensures stronger gripping performance after the liner hanger is set.
Heavy-Duty Anchoring Performance
The slips are designed to provide strong casing wall engagement and reliable liner suspension, especially for long liners and demanding completion operations.
Large Slip Contact Area
The large slip design increases contact area with the casing wall, helping distribute load more effectively and improving hanging capacity for long liner strings.
Compatible with Hydraulic Liner Hanger Systems
Premium slips are designed for hydraulic liner hanger systems and can be used in liner running, liner suspension, and liner cementing applications.
AISI 4130 / 4140 H2S-Resistant Material Options
For harsh or sour service well conditions, the slips can be manufactured from AISI 4130 / 4140 H2S-resistant alloy steel according to working conditions and customer requirements.
Replacement Slips Available
Replacement premium slips can be manufactured according to original tool models, samples, drawings, or anchoring requirements, helping customers reduce replacement cost and downtime.
Suitable for Complex Wellbores
These slips are suitable for highly deviated wells, horizontal wells, deep wells, and complex well sections where reliable anchoring is critical.
Applications
Premium slips are widely used in:
Oil and gas well completion
Hydraulic liner hanger systems
Liner running operations
Liner cementing operations
Long liner suspension
Highly deviated wells
Horizontal wells
Deep well completion
Replacement liner hanger tools
Sour service wells upon material selection
Onshore and offshore well construction
Quality Control

| Tooth Hardness Check | Verifies carburized or case-hardened tooth surface when required |
| Surface Inspection | Checks finish quality and protection of premium slip areas |
| H2S Service Review | Checks sour service material requirement when H2S-resistant material is specified |
| Function Check | Ensures slip movement and setting response are smooth |
| Final Inspection | Ensures premium slips are ready for downhole operation |
FAQ
What are premium slips used for?
Premium slips are used in hydraulic liner hanger systems to grip the casing wall and support the liner string after the hanger is set.
How do premium slips prevent premature setting?
Protected premium slips are designed to reduce unwanted casing contact during running. This helps lower the risk of premature setting in tight spots, doglegs, casing deformation, or complex well sections.
What is the benefit of carburized or case-hardened slip teeth?
