Outstanding performance and development trend of stamping elbow

Stamping elbow and other performance comparison

1. Long-term pressure resistance performance, only from the design stress, the pressure resistance performance of the national standard stamping elbow is better. However, due to various factors, the actual wall thickness of the floor heating pipe is usually 2 mm. Under this wall thickness, all kinds of pipes can meet the requirements of floor heating, and the pressure resistance of stamping elbow pipe can not be reflected;

2, low temperature thermal shock resistance: PE--RT and PEX low temperature impact resistance is better. The pipe is not easily damaged by impact during construction in winter, which increases the flexibility of construction arrangements.

3. Environmental protection: PE-RT can be recycled and used without polluting the environment. However, PEX cannot be recycled and will cause secondary pollution.

Development trend of stamping elbow pipe

The punching elbow raw material not only has a qualified creep breaking curve, but also the pipe price is moderate, the construction is convenient and fast compared with other varieties, and the connection form belongs to the form of the reliable local inter-melting hot-melt connection at the present stage, and the hole diameter of the pipe part is larger than the same The inner diameter of the gauge pipe is relatively small in the system because there is no mechanical connection of the local diameter reduction.
