Casing Systems

MSD Casing Systems Product Range

MSD supplies casing systems for overburden drilling, with product pages covering four casing advancement system structures and two related component groups. Use the links below to review each product type, then confirm the required dimensions, drilling equipment and supply scope before ordering.

Casing Advancement System Types

The Eccentric Casing System uses an eccentric reamer that moves outward during drilling to cut a hole larger than the casing outside diameter. This allows the casing to advance with the drilling assembly; the reamer can then retract for retrieval through the casing.

The standard Concentric Casing System uses a pilot and fixed ring-bit arrangement working on the same drilling axis while the casing advances.

The Slide Block Casing System uses discrete blocks that move outward in guide slots to create the reaming diameter around a center bit. Its retrievable block structure is different from the standard concentric fixed ring-bit system.

The Concentric Casing System with Wings is identified by its Overburden Wing Bit configurations. The wing opening, retraction and actuation sequence must be confirmed from the technical drawing or model-specific information and is not inferred here.

Casing Tubes and Casing Shoes

Casing tubes and casing shoes are related components within a casing configuration; they are not separate complete casing advancement systems. The required tube dimensions, wall thickness, connection, shoe configuration and matching system parts should be checked together. The exact supply scope may include a complete system or selected components.

How to Select a Casing System

Selection begins with the required hole and casing dimensions, the drilling application, the ground or formation condition, and the drilling method. The drilling rig, DTH hammer or drifter, casing connection, required cased length and intended component supply should also be reviewed. Product names or nominal dimensions alone do not confirm that parts are interchangeable.

System Configuration and Compatibility Review

A casing system should be reviewed as a complete configuration. Confirm the pilot or center tool, reaming or ring component, casing tube, casing shoe, hammer or drifter and relevant connection dimensions against the selected product data. For replacements, use the existing model, markings, measured dimensions, drawings, photographs or samples to support the review. Similar names or nominal sizes must not be treated as proof of compatibility.

MSD Manufacturing and Technical Support

MSD is a China-based rock drilling tools manufacturer with 23 years of experience, exporting to more than 40 countries. Its range includes casing systems and related drilling products, supported by ISO 9001 quality management and technical configuration review. Customers can provide project and equipment information for product selection or replacement enquiries.

Information Required for a Quotation

To prepare a casing system selection or quotation, provide:

• Project type and drilling application;

• Drilling method;

• Formation or ground condition;

• Required hole diameter and casing dimensions;

• Casing wall thickness, connection and required cased length;

• Drilling rig and DTH hammer or drifter information;

• Required system components and quantities;

• Existing model numbers, markings, drawings, photographs, measurements or samples for replacement enquiries.

Request a configuration review. Send the project/application, drilling method, ground condition, hole and casing dimensions, equipment information and required quantities so MSD can check the relevant product configuration.
