HSM-1 Premium Connection

13-02-07 From   Font size【BigMidSmall

HSM-1 is a versatile high performance non upset premium coupling connection with extra gas tightness properties and excellent structural strength, suitable for use in a combination of environments and well conditions

size range:  2-3/8″13-3/8 ″

 

Description

l                                Threaded and coupled connection

(1)Threaded and coupled connection, coupling critical cross sections greater than those of the pipe body and the coupling covers the vanishing threads, Joint efficiency is more than 100%;

l                                Improved buttress thread form:

(1) Improved buttress thread form with a taper of 1:16easy stabbing without cross-threading and fast trouble-free make-up.

   2 3/8"-2 7/8"   8TPI

3 1/2"-4 1/2"   6TPI

5" and over     5TPI

(2) Box and pin different thread height design, clearance between the pin thread crest and box thread root avoids the trapping of compound inside the threads.

l                                Tapered metal-to-metal seal

1 Tapered metal-to-metal seal, offers excellent gas tightness with high contact pressure and long contact length ; minimizing galling risks during make uppreserving seal integrity after repeated make-ups and break-outs

 (2)  Seal is generated by radial interference, reducing the effects of tensile load. Seal mechanism energized by internal and external pressure.

l                                Reverse angle torque shoulder

1The wedge effect created by the reverse angle improves the structural strength of the connection.

2internal torque shoulder provides positive stop and effective protection against overtorquing.

l                                Internal flush design

Internal flush design reduces the gas and liquid turbulence and minimizes the energy loss in the pipe.

l                                Special clearance coupling

Special clearance coupling option is available on request.

Benefits

Excellent gas-tightness.

Superior structural strength

Excellent resistance to galling

Applications

Production tubing and casing

Surface casing

Intermediate casing
