ISO 4023:2009 specifies test methods in which a rubber hose test piece or hose assely is exposed to saturated steam, thus simulating service conditions. Four methods are specified, namely: method A: vertical rack method; method B: horizontal rack method; method C: flexing test, vertical arrangement; method D: flexing test, horizontal arrangement.
Following the fire exposure test, a hose stream is directed first at the middle and then at all parts of the fire assely that were exposed to heat. The stream is delivered through 2 1/2-inch (63.5 millimeter) hose and discharged through play pipe constructed in accordance with Underwriters Laboratories (UL) 385, Standard for Play Pipes for Water Supply Testing in Fire Protection …
Hose is subjected to saturated steam to simulate service conditions in four different methods.
Steam moving through a line at high speeds picks up condensate in the bottom of the pipes, much like wind blowing across a lake forms waves. When the high speed steam and condensate come to a bend, such as a ‘Tee’ or 90 Degree turn, the steam makes the transition, but the water slams into the side wall of the pipe. A pulsing action results in a hammer-like action called …

Dry or wet. Saturated or superheated. Whatever state your steam is in, you need a high quality hose to handle it efficiently and safely. Gates industrial steam hoses are engineered to withstand the high pressures and high temperatures that makes steam one of the toughest hose appliions in the industry. Whatever your industry demands, you can always count on Gates.
Composite Hose Testing. Hose asselies with 1 inch to 4 inches nominal bore standard duty oil and chemical hose are tested to 1-1/2 x MAWP of the assely for a minimum period of five minutes. Hose asselies with 6 inches to 10 inches nominal bore composite hose are tested to 1-1/2 x MAWP of the assely for a minimum of 30 minutes.
Hydrostatic testing is the most used leakage checking method for piping networks. ASME B31.3 Process piping code specifies criteria for hydrotesting in a process industry. Test Fluid As per ASME B31.3 Section 345.4.1, the test fluid shall be water unless there is the possibility of damage due to freezing or if water will casue adverse effect on […]
testing of hydraulic hose asselies and pertains to nominal internal diameters 1/8 inch through 4 inch (3.2 mm through 101.6 mm). Its intended audience is warehouse fabriing personnel. This document will define the best practices and procedures for how to make a hydraulic hose assely. It is extremely important that the specific instructions of the hose and coupling …
The SAE J343 standard gives methods for testing and evaluatinig the performance of the SAE 100R series hydraulic hose and hose asselies (hose and attached end fittings) used in hydraulic systems. Proof Pressure Test. This proof test is conducted at twice the working pressure of the hose unless otherwise specified by the customer. The test

5. Be sure and use recommended steam hose couplings and clamps on hose. MAINTENANCE OF STEAM HOSE 1. Periodic inspection of hose should include looking for cover blisters and lumps. 2. Check for kinked areas that could damage hose. 3. Drain hose after each use to avoid tube damage before hose is put back in operation, to avoid "popcorning" of
Steam hoses are tested at a test pressure of five times the operating pressure. If the inlays of the steam hose (under the surface) have been severely damaged, for example by corrosion, or if the inlays have been weakened by a sharp object, the hose will crack prematurely. Hoses that pass the test can be put safely back into use.
The most common diameters of steam tracing are 3/8 in. (9.52 mm) and 1/2 in. (12.7 mm) OD copper or stainless steel tubing. Diameters of 5/8 in. (15.88 mm) and 3/4 in. (19.05 mm) OD tubing have been used; however, this entails greater expense. Tubing that is 3/8 in. is more easily plugged by sediment and/or debris, so it is less frequently used.
After approximately. one minute, visually inspect hose and couplings for any leaking or unusual conditions. If any unusual. conditions appear contact the appropriate person for disposition of the hose. Hold pressure at the working pressure long enough to check for leaks and perform any measurements. required.
hose-stream test. A test in which, after a period of fire exposure, a wall partition or door is subjected to the impact, erosion, and cooling effects of a stream of water from a fire hose directed first at the middle and then at all parts of the exposed face. McGraw-Hill Dictionary of Architecture and Construction.
d. Place the hose on a clean, dry, nonconductive surface. e. Test the cut length for electrical conductivity (see steps below). i. This will ensure that the length of hose is a qualified component from which to fabrie a conductive hose assely. ii. The finished/fabried hose assely also requires conductivity testing.

The test hose stream is delivered through a 63.5mm (2 1/2 inch) hose at a nozzle pressure of 30 psi (207 kPa), at 6.1 metres (20 feet) from the centre of the exposed test panel. The whole test panel surface is progressively subjected to hose stream exposure. After a long exposure fire resistance test each square metre of the hot test panel
30/8/2017· Steam Hose - 10:1 ratio; For additional safety precautions and abrasion resistance, it is recommended to utilize a hose sleeve or guard based on the appliion. Cold flex test. Hydraulic hose manufacturers rely on cold flexibility tests, using guidelines such as ISO 10619, to design and rate their hydraulic hose products. When tested, the sample’s hose or cover …
Codes apply hose stream test unevenly. Glazing is held to a higher standard. NFPA 251, ICC model codes and ASTM E-119 specifically exclude fire-rated construction of less than one hour from the hose stream test requirement. Yet, 45-minute glazing, which is limited to no more than 25% of the total wall area must pass the hose stream test.
The sample hose has to withstand 30 seconds at the minimum burst pressure. At this pressure, there should be no signs of leakage from the hose or any fittings being tested. HYDRAULIC HOSE PROOF PRESSURE TEST The proof pressure test takes the hose and fitting assely up to working pressure. That pressure is held for a minimum of 30 seconds.
