Yowin chooses a different method to fabricate our custom braided natural gas hoses. We have a proprietary method of preparing the hose for welding that is different than our competitors. It involves how we form the hose core and how it relates to the braid and the braided band that ties all 3 together. During prep, we perform a process that thins out the wall of the end fitting so that when welded to the hose we get full penetration and that removes the hinge point we referenced earlier. The result is our flex steel braided gas hoses are stronger and more durable for a longer-lasting flexible hose assembly over time. This also creates a smooth transition between the hose core and the end fitting. It also removes sharp edges of the core that can interfere with flow inside the flexible metallic hose.

Our hose assemblies are cleaned several times throughout the process. Once before prep and welding and then a final cleaning after pressure testing. During the final cleaning process, Yowin pickles the welds to remove impurities (carbon) that have risen to the surface during the cooldown of the weld. This prevents any rusting on the welds once it hits moisture in the air or environment it’s installed in. Our competitors only use soap and water and in some cases a mild citric passivization. This is not strong enough to remove the impurities in the weld and that weld will rust within hours or days once in the field. These are just a few things that set us apart from the rest of the flexible SS braided hose industry. We hope that you make the right choice and choose Yowin for your next flexible braided gas hose manufacturer!
