JL-22 / JL-29 Casing Heads for Oil & Gas Wellhead Systems

The JL-22 / JL-29 Casing Heads are wellhead components designed to support casing hanger installation and provide a reliable interface between casing strings and other wellhead equipment. Their straight-bore bowl configuration incorporates a 45° landing shoulder, creating a practical design for protecting critical sealing areas during drilling and wellhead operations.

The casing heads are engineered to help reduce the risk of damage caused by drilling tools entering the bowl area. The landing shoulder arrangement also helps prevent wedging issues involving test plugs and bowl protectors when pressure is applied.

With multiple outlet and bottom connection configurations available, the JL-22 and JL-29 series can be adapted to different wellhead installation requirements.

Straight-Bore Bowl with 45° Landing Shoulder

A key feature of the JL-22 / JL-29 design is the straight-bore bowl combined with a 45-degree landing shoulder.

This configuration helps protect the sealing surfaces from potential contact with drilling tools. It is also designed to reduce the possibility of test plugs or bowl protectors becoming wedged during pressure application.

The result is a wellhead casing head configuration focused on practical installation, sealing-area protection, and compatibility with different casing hanger arrangements.

Casing Hanger Compatibility

The casing heads are designed to accommodate a broad selection of slip-type and mandrel-type casing hangers.

This versatility allows the same casing head platform to be configured for different casing suspension requirements and wellhead arrangements.

For deeper drilling applications, the JL-29 configuration uses a longer bowl design compared with the JL-22. The extended bowl accommodates the JL-29 casing hanger, which provides a larger load-bearing capacity for applications involving deeper wells.

JL-22 / JL-29 Configuration Options

Several design variants are available to meet different operational requirements.

JL-22-BP / JL-29-BP

The BP versions incorporate additional lockscrews designed for bowl protection. This configuration provides an additional mechanical feature for protecting and securing the bowl area.

JL-22-L / JL-29-L

The L versions are equipped with lockscrew provisions that can be used to retain the casing hanger.

These configuration options allow the casing head to be selected according to the required hanger retention and bowl protection arrangement.

Outlet Configurations

The JL-22 / JL-29 casing heads can be supplied with different outlet arrangements for connection to the wellhead system.

Available outlet types include:

• Line Pipe Outlets

• Flanged Outlets

• Extended Flanged Outlets

The standard configuration is normally supplied with threaded outlets, while studded outlets can be provided when specifically requested.

This range of outlet options allows the casing head to be matched with different wellhead piping and connection requirements.

Bottom Connection Options

Different bottom preparation configurations are available to accommodate various installation conditions.

The available options include:

• SOW (Slip-On-Weld)

• SOW with O-Ring

• Threaded Connection

• Sure Lock Connection

These alternatives provide flexibility when integrating the casing head with different casing and wellhead arrangements.

Main Product Features

The JL-22 / JL-29 series offers several configuration and design characteristics for oil and gas wellhead applications:

• Straight-bore bowl design

• 45° landing shoulder configuration

• Protection of sealing areas from drilling-tool contact

• Reduced risk of test plug and bowl protector wedging under pressure

• Compatibility with various slip and mandrel casing hangers

• Additional bowl protection option with BP versions

• Lockscrew hanger-retention option with L versions

• Line pipe, flanged, and extended flanged outlet configurations

• Multiple bottom connection options

• Threaded outlets as standard configuration

• Studded outlets available upon request

• Longer bowl configuration for JL-29 applications requiring higher casing hanger load capacity

Typical Wellhead Applications

The JL-22 / JL-29 casing heads can be used as part of wellhead assemblies for oil and gas drilling and production operations.

Their configurable outlet and bottom connection arrangements make them suitable for projects requiring specific wellhead interfaces, while the available casing hanger configurations provide flexibility for different casing suspension applications.

The JL-29 configuration is particularly applicable to deeper drilling requirements where the longer bowl and corresponding JL-29 casing hanger provide increased load capacity.

Product Information

Supply and Customization

The JL-22 / JL-29 casing heads are available for industrial and oilfield equipment procurement projects with a minimum order quantity of 1 set.

Customization is supported for selected requirements, including product color, company logo, and packaging. Standard export packaging is provided in an export wooden box to support transportation and handling.

Payment terms can be arranged by T/T, L/C, or mutual agreement. Delivery may be available from stock subject to prior sale, or production can be arranged with a minimum lead time of approximately 15 days.

Reliable Casing Head Configuration for Wellhead Systems

The JL-22 / JL-29 Casing Heads combine a straight-bore bowl, 45° landing shoulder, flexible casing hanger compatibility, and multiple outlet and bottom connection choices into a configurable wellhead component.

With options for bowl protection, hanger retention, outlet styles, and bottom connections, the series can be configured to meet a range of drilling and wellhead installation requirements. The JL-29 longer-bowl design further extends the product range for applications involving deeper drilling and higher casing hanger load requirements.
