Difficulties in making metal hoses
Wall thickness: The thickness of the standard specification is determined, and the wall thickness of the long pipe must be thicker than the standard specification, the pressure received will be higher, and the safety performance will be better.
Outer diameter: The metal hose has been welded, waved, shaped and polished. The longer the bellows, the local irregularities and the larger the diameter; therefore, the longer the bellows, the higher the requirements.
The diameter of the stainless steel hose for air energy is larger than that of the energy-saving water dispenser, the pipe wall is thicker, and the pressure resistance must be better.
Therefore, the common long corrugated pipe is harder than the standard metal corrugated pipe, mainly due to the difference in wall thickness. The long pipe has a greater and more extensive use.
