Depending on the location of the installation, you can see a substantial change of temperature that would require additional flexibility. The number of corrugations on the hose increases so the waves become frequent as we go from wide to compressed pitch. As shown in the Table, the flexibility increases but the compressive strength decreases as the number of nodes increases. The outer coatings (tube) have no fire-preventive specification. Great things happen when the world agrees. For plumbing applications where the pipe may need to be rodded to clear an obstruction. can be manufactured from materials such as stainless steel, carbon steel, chrome coated, brass, chrome coated brass, etc. Note. Any liquid application of 25 feet per second or gas application over 75 feet per second should have a liner. The flexible hoses are manufactured from stainless steel sheet strip. 2- Opaque PVC: It is used for 15266 indoor gas flexes.
