Hilong Gas Sealed Connection

Product Introduction

HLDT-GS® can be used in Drill Stem Testing (DST) operation, hydraulic fracturing, well completion and underbalanced drilling with high metal-to-metal internal seal performance under gas pressure loading. Compared with the traditional single function drill string, using HLDT-GS® drill string can save time and reduce cost.

Product Advantage

Compared to API connections, HLDT-GS® has the following features:
·The use of double shouldered compound sealing structure allows the smooth transition of inner diameter, and smooth metal surface elastic interference fit achieves metal-to-metal seal.
·Seal integrity is not affected by tensile load and multiple drilling trips.

Product Specification

HLDT-GS®26, HLDT-GS®31, HLDT-GS®38, HLDT-GS®40, HLDT-GS®46, HLDT-GS®50, HLDT-GS®55 and HLDT-GS®65, the sealing structure can be applied to API Spec 7-2 and non-API rotary shouldered connections.
