The reinforcing layer is made of a stainless steel woven mesh structure, which greatly improves the pressure resistance and tensile strength of the pipe, and maintains stable structural performance even under high-pressure or frequent vibration environments. The outer layer is wrapped with PVC material, which not only enhances the abrasion and weathering resistance of the pipe, but also provides a good insulating effect and prevents the external environment from influencing the internal part of the pipe, and the use of precision-machined flat gaskets, nuts and flange The use of precision-machined flat gasket, nut and flange joints ensures the tightness and reliability of the pipe joints and facilitates installation and maintenance.
