BL-1T Premium Connection

BL-1T is multifunction connection. The connection can minimize risk caused by load of pressure, temperature, bend, and compress.

• Thread design

• Spec and thread type

• spec：2-3/8″— 13-3/8″

• Thread type and taper

  φ2-3/8"～φ2-7/8″   8TPI , 1:16

  φ3-1/2"～φ4-1/2″ 6 TPI , 1:16

  φ5"～φ13-3/8″ 5 TPI , 1:16

• Modified BTC

• Coupling connection type, the connection strength reaches to or over that of pipe body

• Thread is modified buttress thread with high connecting efficiency, which is easy to process.

• Anti-galling design: it is permitted to makeup and breakout for several times

Metal to metal seal

Seal property: the low angle taper to taper interference seal, further strengthened by the reverse angle torque shoulder. The multi seal configuration ensures the connection to have high seal reliability.

Negative torque shoulder

• Negative torque shoulder provide positive torque stop. So, the make-up torque is accurate. At the same time,The wedge effect caused by the negative torque shoulder provide superior structural strength.

• With the reverse torque shoulder, the joint has high capability to resist the compression, bend and over-torque loads.

Inner hole with lengthened shoulder design

• 15°inner hole with lengthened shoulder, will protect connection.

• Inner flat design reduces the gas and liquid turbulence in the pipe, so lower the energy loss.
