1. Description

1.1 Threaded Connection

Unique golden section proportional tooth shape design, uniform and harmonious thread structure size, stable mechanical structure and excellent bearing performance.

The negative angle bearing design is adopted, with excellent connection performance and 100% bending and compression resistance.

Optimized hook thread design reduces thread collision.

Stepped thread design, easy to make up and not easy to cross thread.

1.2 Sealing Structure

The design of new concept sealing structure improves the leakage resistance of the joint.

The main seal and auxiliary seal adopt non equivalent interference design, highlighting the advantages of the main seal.

1.3 Reverse Angle Torque Shoulder

Negative angle shoulders provide accurate screw positioning.

1.4 Streamlined Internal Profile

The streamlined internal profile minimizes turbulence and energy loss when high-velocity gas flows.

1.5 Coupling Design

The coupling performance meets 100% design requirements, and the outer diameter design is consistent with API standard,

1.6 Connection Low Stress Design

The lower stress design makes the connections reliable in Corrosive condition.

2. Finite Element Analysis on TP-G4

Circumferential stress

The low stress design of the joint makes TP-G4 the best choice for corrosive environment applications.
