Stainless steel metal hose to do what performance test

Stainless steel metal metric hydraulic hose fittings with flexibility, corrosion resistance, high temperature resistance, tensile resistance etc.. To achieve such a sophisticated quality must have strict production processes control, but also the need for strict performance testing to ensure quality. The following sea island for you under the stainless steel metal hydraulic hose fittings must be what strict performance test before they leave the factory.
1 pressure test
Pressure test is also called the strength test, which belongs to the safety performance index test. The test pressure is 1.5 times the nominal pressure, test pressure medium for pure water, the chloride ion content should not exceed 25ppm. Each product must withstand voltage test. By using manual or electric pressure test pump pressure, pressure observation usually available 1.5--4 times of test pressure range of level 1.5 or above or equivalent efficacy of pressure gauge, pressure test instrument. During the experiment, the specimen is placed at one end of the straight hose, install the plug with the exhaust valve, the other end is connected with the pressure test pump outlet pipe, the water will be injected into the tube, exhaust air, exhaust valve closed, and then slowly increased pressure test pressure to the specified value, holding pressure 5min, check the sample status, failure form has no leakage, damage to parts such as abnormal. Requirements for qualified product does not allow failure form of sign of leakage or damage to parts such as abnormal.
2 air tightness test
Air tightness test is also a safety index test, each require a manufactured products are to be tested. Air tightness test in the nominal pressure, qualified products does not allow leakage phenomenon, air tightness test can be carried out in the pressure test qualified rear. Experiments using dry, clean air, or the need to use nitrogen or other protective gas as the test medium. The pressure device can adopt the compressor, air pressure generating device, the cylinder or cylinder group. Pressure observation usually adopts 1.5 grade above or equivalent measurement precision pressure gauge pressure testing instrument, with a full set of test equipment groove. Test specimen is arranged on one end of the hose plug, and the other end of the air outlet is connected with the pressurizing device, gas pressure equal to the nominal pressure, the specimen immersed in the water tank, remove the adsorbed on the net sleeve on the bubble, when the air pressure is stable after the pressure 10min check for gas leakage test piece.
Stainless steel metal hose is commonly used now do all sorts of equipment signal wire, wire and cable transmission, optical fiber protection, it and people's work life. If the product quality problems, will bring some loss. So rigorous performance testing is indispensable, and must be strictly implemented once found the product flaw, should be dealt with immediately, must not hold fluky mentality.

Suddenly leaking pipe joints how to do

In the hydraulic system , both the metal pipe fitting , or hose fittings , there are prone to leakage problems . For ferrule fittings, mostly due to pipeline subject to greater external force or impact, so that the card sleeve loose or deformed face caused by hydraulic adapters , you should check whether the card holder out of round , whether the defect edge , whether the pipe ends intact and nut, compression level , etc., while also eliminating hydraulic hose assemblys force. For flared fittings, mostly due to excessive flaring , quality, undesirable or multiple demolition , resulting in flared cracks or deformation caused by leaks , then you can be re- flared front truncated . If you use a male and female cone top pressure seal , the leakage is mostly due to two cone damage, available on the cone abrasive grit grinding .
    In some with "о" or outer -ring face seal by the occasion , the leakage following reasons : "о" ring aging or deformation caused by leakage ; "о" ring assembly is not in place , so that the two plane connection when pressure is uneven or "о" ring being cut cause leakage ; "о" rings uncompacted , elastic deformation caused by insufficient leakage ; "о" spigot ring groove too deep and cause leaks. In this regard , the need to re-select the same diameter and cross-sectional thick "о" rings can also be sealed with a rabbet plane for cutting grooves or grinding to reduce the rabbet groove depth , so that "о" rings are flexible enough to deformation ( compression should generally be between 0.35-0.65mm ) . For the use of oil and rubber, wool felt, soft steel cardboard, combined sealing gasket or sealant hydraulic hoses joints , whether any material , you should first check the seals for damage , deformation, aging and rough through the large , etc. and then take the appropriate measures.

Flared fittings pre-installed

Pre-installed , you should try to keep the tube and the coaxial connector body , if the pipe deflection is too large will cause seal failure.
    Preloaded force should not be too large. Should make the inner edge ferrule tube wall just embedding , card sets there should be no significant deformation . During pipeline connection, then the provisions of the tightening force assembled . φ6-10mm ferrule tightening force of 64-115N, φ16mmr 259N, φ18mm for 450N. If the pre- deformed when the card holder will lose the seal.

Card sets of pipe joints assembly

Preloaded ① fittings fittings fittings fittings of the most important aspects of pre-installed, directly affects the reliability of the seal. Generally require a dedicated preheater. Small diameter connector can be pre-installed in a vise. In practice, with a connector as the parent, the nut, ferrule onto the tube can be pressed. There are card sets straight couplings, sleeve type end through turn heads, ferrule tube Hydraulic pipe fittings and other types. I found that even in the same factory shipment, these types of connector body tapered hole depth is often not the same, the result is caused by a leak, and this problem is often overlooked. The correct approach is, the pipe end what kind of connector body connection, the corresponding connection terminal is preloaded with the same type of connector, so to avoid possible leakage problems. ② pipe end should be flush. After sawing the pipe should be flush grinding wheel and other tools, and deburring, cleaning with high-pressure air to blow before use. ③ pre-installed, you should try to keep the tube and the coaxial connector body, if the pipe deflection is too large will cause seal failure. ④ preloaded force should not be too large so that the ferrule tube embedded in the outer wall just inside the edge, card sets shall have no deformation. During pipeline connection, then the provisions of the tightening force assembled. ф6-1 card sets tightening force is 64-1 15n, 16фmmr 259n, ф18mm for 450n. If the pre-deformed when the card holder will lose the seal. (Two). Prohibit adding sealant filler. It was sealed in order to achieve better results, ferrules, apply sealant, sealant was the result into the hydraulic system, hydraulic components causing blockage damping hole fault. (III). Connecting pipe should be sufficient deformation of the tube margin, to prevent the tube subjected to tensile strength. (Four). Connecting pipe should avoid subjecting it to lateral forces, lateral forces caused Mifengbuyan over the General Assembly. (Five). Connecting pipe should be a good one, to avoid multiple disassemble, otherwise it will seal performance deteriorated.

Fittings and installation methods of prevention

In the hydraulic system, both the metal pipe fitting, or hose fittings, there are prone to leakage problems. Hydraulic pipe fittings, mostly due to pipeline subject to greater external force or impact force, the card sets loose or deformed face caused by leaking pipe, you should check whether the card holder out of round, edge whether the defect, the pipe end is intact and nut, compression level, etc., while also eliminating pipeline force. For flared fittings, mostly due to excessive flaring, quality, undesirable or multiple demolition, resulting in flared cracks or deformation caused by leaks, then you can be re-flared front truncated. If you use a male and female cone top pressure seal, the leakage is mostly due to two cone damage, available on the cone abrasive grit grinding. In some with "о" or outer-ring face seal by the occasion, the leakage following reasons: "о" ring aging or deformation caused by leakage; "о" ring assembly is not in place, so that the two plane connection when pressure is uneven or "о" ring is cut resulting in leakage.
