English expression fittings

Some of pipe fittings industry jargon is no specific point in the online English translation, the major off pipe fittings manufacturers also do not have English Introduction. Such as tube fittings, terminal through connector, plug-welding elbow, two-way connector body and so on. Tee: three-way pipe connector terminal through connector: Straight thread connector plug welding elbow: Through welded elbow-way connector body: bidirectional Hydraulic ferrules pipe fittings, intubation pieces, threaded pipe fittings Butt-English names are welding fitting (referred BW Fitting), Socket welding fitting (abbreviated SW fitting), Threaded fitting. Fittings, pipe fittings may be on domestic non-standard argument. About the tee, is divided into equal tee (Equal Tee), also known as straight tee (Straight Tee), and reducing tee or Reducing Tee (Reducing Tee), in the actual business dealings, the general would not have said fitting it.

Cracking Analysis of high-pressure metal hoses

Chemical composition of the base metal hoses meet the standard requirements , microstructure normal . Failure hose member and the base metal and weld finished piece unused micro-cracks are present on the hose , the hose which indicates that micro-cracks before they are used . According to the position and shape of micro-cracks can be divided into two categories: one is located on the weld , the weld along the direction of the main direction of the crack , in addition to many cracks perpendicular to the main secondary cracks , these cracks are located weld intergranular columnar crystal Hydraulic tube fittings is formed when the welding weld cracking ; second crest of microcracks in the inner surface of the hose , these micro- cracks in the circumferential direction along the hose (Up direction perpendicular to the weld ). and substantially parallel to each other , since the majority of these micro-cracks exist in the inner surface of the crest , and the analyzes were performed by location and morphology with regularity , so these cracks should be rolling waves generated when processing cracks. In welding and molding process , the micro crack initiation at the inner surface of the hose in the subsequent assembly process of trial and the use of extended fatigue microcracks , finally cracked through , causing oil spills . Recommended welding hose and processing to improve, in order to avoid the generation of microcracks .

Metal hose is an essential component of modern pipeline

Metal hose because it has a good seal, pressure resistance, high temperature resistance, corrosion resistance, and certain other properties available around the song has become an essential component of modern pipeline. Metal hose can be used for chemical piping systems superheated vapor tube, Hydraulic ferrules and pneumatic equipment, high-pressure pipeline, the transmission medium, pipes and other drug burst, the role is to absorb the reciprocating movement, absorb thermal expansion, vibration absorption, compensation pipe installation deviation. Because metal hose complicated forces at work, poor working conditions, so the accurate representation of the force metal hose there are considerable difficulties. Largely by the bellows metal hose, and fittings nets three parts. Corrugated metal hose pipe is the subject of the role played around; nets from enhanced shielding effect; joint plays a role in the connection.

Metal hose reel machine nonmetal parts cleaning method

Metal hose reel machine nonmetal parts cleaning method - in metal hose machine with metal parts , there are also non-metallic parts, metal hose machine maintenance , it is necessary for some spare parts for cleaning. Clean metal parts , generally diesel , petrol or cleaning agents. However, in cleaning metallic parts, can not be used diesel oil, gasoline and the like for cleaning it. Otherwise, it will make some non-metallic parts deformation , deterioration or failure . Therefore, the non-metallic parts should be based on different materials , use of different Hydraulic pipe fittings.1 , is to clean friction plate, such as the clutch friction plate, brake linings , etc., can only use petrol to clean.2, which is made ​​of rubber parts cleaning , such as rubber sheet , aprons , etc., should be cleaned with alcohol or brake fluid .3 , is to clean paper parts, can not be washed with water in the diesel fuel to clean.4 , is made ​​of parts cleaning foam should use detergent or soap and water.5 , is to clean leather accessories, such as drive belts , etc., they can be washed or wiped clean with a cloth

Metal hose selection

For a given length and specifications of metal hoses, their ability to withstand stress and shock have certain limits, therefore, when used according to the actual situation. Generally used nominal diameter Hydraulic hose fittings the same nominal diameter, hose length array according to Shen tank temperature deformation, misalignment and earthquakes and other factors to determine the lateral displacement produced. The metal bellows tube, nets of three parts and connectors, bellows are made ​​of stainless steel, has a good flexibility, its longitudinal rigidity and bending rigidity is small, within a radius of curvature at the rated working, with a strong corrosion resistance and good temperature stability. Nets from strengthening the role of the metal hose has a large carrying capacity. Therefore, the metal hose with shock, subjected to bending, absorb stress.

Resistant metal hose

Resistant metal hose coal injection system in ironmaking, steelmaking refining furnace and other solid materials to ease the occasion, with ordinary metal hose soon frayed, Huasheng pipe fittings manufactured using wear resistant stainless steel corrugated hose advanced technology from developed, proved through practice, high-speed flow in the pipe body particle abrasion, long service life.
Wear-resistant metal Hydraulic hose fittings body using multi-layer composite structure, followed by heat from outside to inside layer of asbestos cloth, wire mesh layer, a metal layer and a trapezoidal cross-section bellows wound metal hose layer. Its layers and hoop ends welded together tight combinations, hose quick connector used between the body. The metal hose better solution because partial burning of the surface and the inner tube wear two major problems affecting the service life of metal hose, metal hose and compared to similar existing product life greatly improved, the relative cost of production significantly reduced iron plant particularly suitable application technique used in pulverized coal injection.

Corrugated metal hose is a modern industrial pipeline a high quality flexible pipe

Corrugated metal hose ( short hose ) is a modern industrial pipeline a high quality flexible pipe . It mainly consists of bellows, nets and joint components. Its inner tube is a spiral or annular waveform walled stainless steel bellows , bellows outer nets, is made of stainless steel wire or woven according to certain parameters . Hose Hydraulic tube fittings or flanges at both ends of the pipe joints with customers or flange mating .Bellows hose is made of very thin-walled stainless steel seamless or longitudinal weld precision plastic processing after forming . Because the elastic property of the bellows determine the contour hose has good flexibility and fatigue resistance , making it very easy to absorb deformation and cyclic loading various sports , especially in the piping system has the ability to compensate for a large amount of displacement . I plant in addition to the original hose sophisticated production equipment, recently introduced from Japan two high-precision , high-tech molded bellows automatic welding production lines, greatly improved the quality of the hose and the hose length is not produced limits , to meet the needs of long hose . Dawn brand hose nominal diameter range of DN4-800mm, length optional. Nets are installed in the pressure line hose main pressure parts , while the bellows from the sheath effect, according to the size of pipeline pressure and locations , you can select one or more layers of stainless steel wire or steel strip weaving, dawn brand hose pressure range is generally PN0.6-32.0Mpa. Up to 42.0MPa. The production of the main part of the material hose is the use of austenitic stainless steel , thus ensuring the hose excellent in heat resistance and corrosion resistance of the hose very wide temperature range , is -196-600 degrees to hose by pipelines through the media choose to apply corrosive stainless steel grades, the corrosion resistance of the hose can be guaranteed . Corrugated metal hose has good flexibility, fatigue resistance, high pressure, high temperature resistance, corrosion resistance , and many other features, it is relative to other hoses ( rubber, plastic hose ) much higher lifetime would therefore it also has a high overall economic efficiency . With the development of modern industry , for high temperature, high pressure hose corrugated metal demand is also getting bigger . Hose Scope: need fully flexible pipes, to prevent vibration premises piping for steam, gas , air, heavy oil, petroleum, chemical -pharmaceutical etc apply.
