First corrugated tube of thickness and the second corrugated tube not only have good pliability, temperature tolerance, resistance to pressure;Also have and preferably subtract
Pinking, thus further function as the function to exhaust manifold integral shock-absorbing.
Preferably, the first corrugated tube is being provided with tilting section with the first straight tube junction;The end of the first straight tube is inclined plane;
First straight tube is inserted in the first corrugated tube, and inclined plane pushes against with the inner surface of tilting section.So, it is inserted in first due to the first straight tube
In corrugated tube, the first corrugated tube is played the effect of support by the first straight tube, improves the structural strength of the first corrugated tube, reduces ripple
Stricture of vagina pipe receives the probability of destruction;And inclined plane pushes against with the inner surface of tilting section, the first corrugated tube and the first straight tube,
Play spacing effect during two straight tube weldings, improve production efficiency.
Preferably, the first corrugated tube and the first straight tube are provided with the interface arrangment cooperated in junction;Described card access node
Structure includes protruding from bulge loop that the first straight tube outer surface arranges and is located on the first corrugated tube and recessed with bulge loop corresponding position
Circle;Bulge loop is connected in recessed circle.So, bulge loop and recessed circle clamping, on the one hand play spacing effect, on the other hand play reinforcement
The effect of the structural strength of the first corrugated tube and the first straight tube junction.
Preferably, the first corrugated tube and the first straight tube are provided with the sealing structure cooperated in junction;Described sealing is tied
Structure includes the groove arranged around the first straight tube outer surface;Sealing ring it is provided with in groove;One end of sealing ring and groove inner surface
Laminating, the other end of sealing ring and the inner surface laminating of the first corrugated tube.So, the effect of reinforcement sealing further is played.
