Description

Technical Field

[0001] This utility model relates to a braided gas pipe connection end structure and belongs to the field of gas pipe technology. Background Technology

[0002] Gas pipes are specialized pipelines for transporting combustible gases. They utilize flexible metal gas hoses instead of traditional clip-on rubber hoses, overcoming the drawbacks of rubber hoses such as easy detachment, aging, susceptibility to insect damage, and short lifespan. Gas pipes are characterized by easy installation, reliable connections, corrosion resistance, non-clogging, good flexibility, long service life, and the ability to be bent freely without deformation or gas obstruction. The soft protective surface material provides enhanced safety, easier cleaning, and an aesthetically pleasing appearance. Stainless steel threaded metal hoses have a service life of 8 years.

[0003] In existing technologies, gas pipes are usually used in conjunction with connecting terminals to connect to gas cylinders. However, existing connecting terminals have poor sealing when connecting gas cylinder openings and gas pipes, which can lead to gas leakage. To address this, we have designed a braided gas pipe connecting terminal structure. Utility Model Content
