SS304 Flexible Hose: Corrugated Tube vs Braided Reinforcement Explained

A corrugated tube and a wire braid do two different jobs in the same SS304 flexible hose, not two different hose types you pick between. The corrugated tube is the inner, pressure-containing wall. Its ridged, accordion-style profile is what gives the hose flexibility, letting it bend and absorb vibration without cracking the way a straight pipe would. The braid sits outside the corrugated tube as a woven layer of fine stainless steel wire. Its job is mechanical, not sealing: it restrains the corrugated tube from ballooning outward under internal pressure and protects the tube wall from external abrasion, impact, and kinking during installation or handling. Buyers searching for corrugated vs braided hose are usually trying to work out whether they need one feature or the other. For SS304 flexible hose used in PH plumbing, fire protection, and process piping, the answer is both: the corrugated tube carries the fluid and the pressure, the braid carries the mechanical load that keeps the tube intact at rated pressure. A hose with only a corrugated tube and no braid will have a lower safe working pressure than the same tube reinforced with braid, which is why braid is standard on pressure-rated SS304 flexible hose rather than an optional upgrade.

Single braid adds one woven layer of stainless steel wire over the corrugated tube. It raises the safe working pressure and gives the hose resistance to abrasion and minor impact, which covers most commercial plumbing, booster pump connections, and general process piping found on PH job sites. Double braid adds a second woven layer over the first. The extra layer raises the pressure rating further and adds resistance to pulsation and vibration fatigue, which matters on lines with frequent pressure cycling, such as pump discharge lines on duplex or triplex booster systems, or on lines where the hose absorbs movement between equipment that is not perfectly aligned. Double braid costs more than single braid for the same tube size because of the added wire and labor, so it is worth specifying only where the pressure, pulsation, or vibration profile of the installation calls for it. If you are not certain which your application needs, the safest approach is to describe the fluid, operating pressure, temperature, and whether the line sees pressure cycling when you request a quote. JOHOB sizes the braid configuration to the application rather than defaulting to one spec across every order.

JOHOB supplies SS304 flexible hose in DN15 to DN100, rated PN10 or PN16, with BSP, NPT, or flanged (ANSI) end connections. Custom lengths and end-fitting combinations are available through fabrication rather than only fixed stock lengths, so a hose spec that does not match a catalog size can still be ordered. Standard lead time is 21 to 35 days ex-stock for configurations already in inventory, and 45 to 90 days made to order for custom lengths, sizes, or end-fitting combinations outside standard stock. JOHOB responds to RFQs within 1 business day, which matters when a hose spec needs to be confirmed against a project drawing before a formal quote can be issued. Pricing is quote-based rather than published on the site, since the final price depends on tube size, braid configuration (single or double), end-fitting type, and length. Buyers who are VAT-registered are charged the standard 12% VAT. PEZA and SBMA locators and exporters qualify for zero-VAT treatment, which should be flagged at the RFQ stage so the quote reflects the correct tax treatment from the start rather than being corrected after an order is placed.

SS304 flexible hose from JOHOB is sourced through an ISO 9001 certified partner factory and is TUV SUD tested. CE marking does not apply to this product category: CE marking covers electrical equipment and material handling equipment such as scissor lifts, not piping accessories like flexible hose. If a quote or spec sheet for a competing hose claims CE marking on the hose itself, that claim is outside the scope CE marking actually covers for this kind of product, and it is worth asking the supplier to show which CE directive applies and why. For buyers who need to document traceability or material certification for a project file, ask for the material test certificate and ISO 9001 documentation from JOHOB at RFQ stage rather than assuming it will be included by default with every order. Confirming this upfront avoids delays at project handover when a compliance document is requested and was not part of the original paperwork package.

To order SS304 flexible hose, send JOHOB the tube size (DN), pressure rating (PN10 or PN16), braid configuration (single or double), end connection type (BSP, NPT, or flanged), and overall length. If the exact size or end-fitting combination is not a standard stock item, flag that at RFQ stage so it can be quoted as a made-to-order fabrication with the correct 45 to 90 day lead time instead of the 21 to 35 day ex-stock lead time. JOHOB delivers nationwide across the Philippines, covering NCR, Luzon, Visayas, and Mindanao, including PEZA and SBMA zones. Expect a response to your RFQ within 1 business day, with a formal quote following once the size, braid, and end-fitting spec are confirmed. Pricing is quote-based and varies with tube size, braid configuration, and end-fitting type, so two orders for the same nominal diameter can carry different prices depending on configuration. If the installation requires material test certificates or ISO 9001 documentation for a project file, request these at the same time as the RFQ so they are issued alongside the formal quote.
