Requirements for stainless steel corrugated pipes:
1. The geometric dimensions are within the allowable deviation range.
2. The surface of the stainless steel corrugated pipe is smooth and clean, the welds are flat, and there are no defects such as pores, cracks, slag inclusions, and splashes.
3. The thickness of stainless steel bellows is ≥40um, and the coating must be uniform.
4. Stainless steel corrugated pipes should be prevented from collision during transportation, loading and unloading. If the galvanized layer is damaged, additional coating should be applied in time.
Stainless steel corrugated pipe has the following advantages:
1. Simple structure, convenient to manufacture and maintain.
2. The working stroke is small and the opening and closing time is short.
3. Good sealing performance, small friction between sealing surfaces and long service life.
The disadvantages of stainless steel corrugated pipes are as follows:
1. The fluid resistance is large and the force required to open and close is large.
2. Not suitable for media with particles, high viscosity, and easy coking.
3. Poor adjustment performance.
