Product Description

Product Description

 

 

Cold rolled seamless pipes represent the pinnacle of precision engineering in the realm of seamless steel pipes. Renowned for their high dimensional accuracy and impeccable surface smoothness, these pipes are indispensable in the creation of mechanical structures and hydraulic equipment. The process of cold rolling endows these pipes with a superior degree of dimensional accuracy compared to their hot-rolled counterparts, making them a top choice for applications demanding the utmost precision.
Advantages:
Our cold rolling technology offers an unparalleled edge with its rapid forming speed and impressive output, all while ensuring the coating remains unscathed. This remarkable process endows steel with the ability to adopt a wide variety of cross-sectional forms, tailored to meet diverse usage conditions. Moreover, cold rolling induces significant plastic deformation within the steel, thereby enhancing its yield point and structural integrity.

 

Precision cold drawn pipes have the characteristics of high precision, high smoothness, good inner wall cleanliness, steel pipes can withstand high pressure without leakage, cold bending without deformation, expansion and flattening without cracks, and can undergo various complex deformations and mechanical processing treatments.

Product application

 

Our product boasts an impressive versatility, perfectly suited for a wide spectrum of applications, particularly in the manufacturing of automotive parts, motorcycle components, and hydraulic engineering machinery. Its adaptability and high performance make it a preferred choice across these dynamic industries.
