Dalipal DLP-T4 Premium Connection Casing Records a 7,014.41-Metre Installation

Dalipal’s official announcement provides a shale-gas application reference with a specified casing size, steel grade and actual running depth.

Dalipal Holdings reported that its 139.7 × 12.7 mm DLP140V casing with DLP-T4 premium connections was successfully run to an actual depth of 7,014.41 metres on July 16, 2022.

The company described this as its deepest premium connection installation at the time. The announcement also referenced procurement for CNPC’s southern Sichuan shale-gas projects. [1]

For buyers researching Chinese premium connections, this provides a documented application tied to a defined product configuration.

Reading the Application Data Correctly

The reported depth belongs to that particular installation. It is not a universal depth rating for every DLP-T4 component.

When evaluating a similar requirement, buyers need the relevant connection data for the specified size, material and loading conditions. A casing-string application also does not automatically establish the performance of a custom crossover or other accessory with a different body geometry.

The field record provides a starting point for technical discussion; project acceptance and product suitability remain specific to the requirement.

From a Specified Connection to Matching Accessories

A procurement package involving DLP-T4 may also require pup joints, crossovers, couplings or threaded tool components.

To evaluate these parts, the connection designation needs to be considered together with the outside diameter, weight or wall thickness, bore, material and overall length. For crossovers, both end connections must be clearly identified.

Agreeing these details early helps establish a clear basis for manufacturing, inspection and delivery documentation.
