3 x 6m SS Flexible Hose vs Stainless Steel Hose C/W Single Braided

PH tender documents and BOQs often describe the same hose two different ways in different line items: one by size ("3 x 6m SS flexible hose") and another by construction ("stainless steel hose c/w single braided"). In most cases these point to the same product, a corrugated SS304 inner tube with a single outer layer of SS304 wire braid, cut to a 3-inch nominal diameter and an overall 6-meter length. They are not guaranteed to match, though. A size-only line item does not confirm the braid layer count, and a construction-only line item does not confirm the diameter or length, so two entries in the same BOQ can technically describe different hoses even when a reader assumes they are duplicates. Before ordering against either description, confirm three things: the steel grade (SS304 versus SS316), the braid configuration (single versus double layer), and the end connection (threaded, flanged, or welded). JOHOB reviews both spec lines during RFQ intake and fabricates to the actual combination the buyer needs rather than assuming the two descriptions are interchangeable. If you are unsure which line item is authoritative, send both descriptions in the same RFQ and note which document each came from, this is the fastest way to get a quote that matches what the project actually requires instead of guessing from one ambiguous line.

"Single braided" refers to a hose assembly with one layer of woven stainless steel wire covering the corrugated inner tube. This is the standard configuration for general plumbing, transfer, and pumping connections where the hose sees normal working pressure and routine flexing. A double-braided hose adds a second overlapping wire layer over the first, which increases abrasion resistance and adds pressure margin, at the cost of a stiffer, heavier assembly that is harder to route through tight bends. Neither configuration is universally correct, the right choice depends on the duty cycle, working pressure, and installation space at the specific connection point. If your BOQ line item only says "c/w single braided" without a pressure rating, that is a signal to confirm the service condition before ordering rather than assume single braid is sufficient by default. Steam and boiler feed lines, high-vibration pump connections, and any run exposed to abrasive contact with other equipment are the situations most likely to call for double braid instead. JOHOB's RFQ process asks for the service condition alongside the size and braid specification so the quoted hose matches the actual installation, not just the literal wording of a spec sheet copied from a previous project.

In a "3 x 6m" spec, the 3-inch figure is the nominal diameter of the hose bore (commonly written as DN80 in metric piping standards), and the 6-meter figure is the overall assembly length from end fitting to end fitting, not just the flexible hose barrel. A 6-meter run is longer than the short jumper hoses typically used at pump suction and discharge points, and is more common on transfer lines between tanks, pump skids, or booster stations where a single continuous flexible section avoids extra rigid pipe joints. When specifying or reviewing a 3 x 6m line item, confirm whether the 6 meters includes the end fittings and any flange adapters, since some suppliers measure barrel length only while others measure the full installed assembly. This distinction matters for fit-up on site and for comparing quotes from different suppliers on an apples-to-apples basis. It is also worth confirming the pressure rating expected at that length and diameter combination, since longer flexible runs under load behave differently than short jumpers even when the nominal size is identical. Include the intended connection points (pump flange, tank nozzle, header branch) in your RFQ so the quote accounts for the actual installation geometry, not just the two numbers in the spec line.

JOHOB's stainless steel flexible hose is sourced from an ISO 9001 certified partner factory and is TUV SUD tested. These are quality assurance and testing credentials you can request documentation for at RFQ stage, rather than marketing language attached after the fact. JOHOB does not manufacture the hose in-house, it is sourced from a vetted overseas manufacturer and supplied with local warranty and after-sales support, which is the arrangement to expect from any PH industrial supplier working at this scale rather than running its own hose mill. If a project specification calls for documentation beyond a standard mill certificate, raise this during the RFQ stage so it can be confirmed against what the specific batch or fabrication run can support, rather than assumed after the order is placed. Supply is nationwide, covering NCR, Luzon, Visayas, and Mindanao, including PEZA, SBMA, and Clark economic zones, which matters for buyers coordinating delivery to a locator site or export-oriented facility. For any project where the specifying engineer or consultant requires third-party certification beyond what is listed here, confirm the exact document type needed before finalizing the quote, since certification paperwork can affect both lead time and cost.

JOHOB prices stainless hose on a quote basis, there is no public price list, because the final cost depends on grade, braid configuration, length, end connections, and quantity. Ex-stock sizes ship in 21 to 35 days, while made-to-order configurations, including custom lengths like a 6-meter run, run 45 to 90 days. RFQs get a response within 1 business day. VAT treatment depends on the buyer: standard VAT-registered buyers pay 12% VAT, while PEZA and SBMA locators and exporters qualify for zero-VAT treatment on the same order, so it is worth confirming your registration status before the quote is finalized rather than after. To get an accurate quote on your first pass, include the nominal size (3-inch or DN80), the exact length required, the braid configuration (single or double), the steel grade if known (SS304 or SS316), the end connection type, the quantity, and your project location or VAT registration status. Submitting both a size-based and a construction-based spec line together, if your BOQ has both, lets JOHOB confirm they describe the same hose before quoting rather than pricing them as two separate items by mistake.

SS flexible hose in this size range shows up most often in three parts of a PH industrial or commercial facility. In pumping and pressure systems, it connects booster, transfer, or submersible pump skids to rigid header pipe, absorbing vibration and minor misalignment at the pump flange. In steam and boiler systems, single-braided stainless hose is used on condensate return and hot water service lines where flexibility is needed but the line does not require the abrasion margin of a double-braid configuration. More broadly, it falls under general piping, fittings, and accessories work alongside ball and gate valves on plumbing and process lines that need a flexible connection point rather than an all-rigid run. Because the hose sits at connection points rather than as a standalone fixture, it is almost always specified alongside the pump, boiler, or valve package it serves, which is why JOHOB quotes it either as a standalone line item against a BOQ or bundled into a larger pumping or steam system package. If your project falls into one of these categories, mention the connected equipment in your RFQ so the hose specification accounts for the actual pressure and vibration environment at that connection.
