Detailed introduction:
Advantages of national standard stamping elbow:
1. Temperature and pressure resistance, good flexibility, heat resistance, and other plastic pipes. Simple installation, good thermal conductivity, suitable for floor heating system, recyclable.
2. The national standard stamping elbow pipe has its impact strength, can be hot melt welded and mechanically connected, and is superior to the thermal conductivity of PB-PP-R.
Development trend of national standard stamping elbow pipe:
The national standard stamping elbow raw material not only has a qualified creep rupture curve, but also has a moderate price. Compared with other varieties, the construction is convenient and fast. The connection form is a reliable form of standard mutual melting and hot-melt connection at this stage. The hole diameter of the pipe fittings is larger than the inner diameter of the pipes of the same specification. In the system, there is no mechanical connection mode of local diameter reduction, Therefore, the system fluid resistance is relatively small.
Performance comparison between national standard stamping elbow and other stamping elbow:
1. Long term pressure resistance, only from the design stress, the pressure resistance of the national standard stamping elbow is good. However, due to various factors, the actual wall thickness of floor heating pipe is usually 2mm. Under this wall thickness, all kinds of pipes can meet the requirements of floor heating, and the pressure resistance advantage of national standard stamping elbow pipe cannot be reflected;
2. Thermal conductivity: pipes used for floor heating need to have good thermal conductivity.
3. Low temperature heat shock resistance: PE-RT and PEX have good low temperature shock resistance. During winter construction, the pipes are not easy to be impacted and broken, which increases the flexibility of construction arrangement.
4. Environmental protection: PE-RT can be recycled and does not pollute the environment. However, PEX can not be recycled, which will cause secondary pollution;
5. Stability of processing performance: PEX has problems such as controlling the crosslinking degree and crosslinking uniformity. The processing is complex and directly affects the pipe performance.
