British Standard Pipe fittings and connectors

bsp swivel fittings and connectors are available in two versions, a parallel thread (BSPP, also known as "G") and a taper thread (BSPT, also known as "R").
The BSPP connection is similar to National Pipe Straight Mechanical (NPSM), except the the thread pitches are different in most sizes. The BSPP female swivel has a tapered nose/Globeseal flareless swivel which seals on the cone seat of the male. While many users mistakenly identify BSPP fittings as metric, these Bsp fittings are actually measured in inches. Some Japanese ( JIS 30°) fittings also use BSPP threads.

SAE 37° use with the following hoses

SAE 37°jic female swivel fitting use with the following hoses:
1、SAE 100R2 AT Hydraulic Hose (R2)
2、SAE 100R16 Hydraulic Hose (R16)
3、SAE 100R17 Hydraulic Hose (R17)
4、Tough Cover hydraulic hose (KT)
5、Hydraulic Jack Hose (HJK)
6、SAE 100R1 AT Hydraulic Hose (R1)
7、SAE 100R3 General Purpose Hose (R3)

How to withhold a satisfactory hose

When the user when to bsp threaded pipe fittings withhold high-pressure pipe , if the withholding amount is too small , then the weight between the connector and the hose is too loose , the role of hydraulic hose withhold there may emerge from the joint in the initial period , if you withhold too large , then connector and hose too tight , easily lead to hose inner being localized damage, cracks , hydraulic oil directly into the steel layer from the rupture , and then he went along the gap between the wire coat tails oozing , or has been channeling along the wire layer to build up somewhere , so that the outer layer of plastic to produce drum kits and even rupture .
When withheld , nor withhold too fast, as is likely to cause damage to the rubber layer and wire breakage , so that the hose in use prematurely. Practical work , the replacement of the high-pressure hydraulic hose, hose length selected , wire layers, joint shape and size to be reasonable , and should minimize the degree of bending of the hose , the majority of the damage is due to the high pressure hose making improper .
Works
Piston pump installed in the bsp female oil in the tank immersed in silent cooling design to achieve scientific purposes , the motor driven piston pumps , hydraulic oil output , push the plunger movement withhold tanks , resulting in mold base radial contraction , and mold squeeze on the hose fitting jacket . When the contraction reached micrometer predetermined value , squeezing automatically stop solenoid valve to change back , reverse movement of the plunger within the cylinder , die along with open, withhold hose complete.

Install npt pipe fittings

1. install npt pipe fittings, screw bolts are toward the outer joint, every bolt flange face of pressure by diagonal method repeatedly evenly tightened to prevent pressure side.
2. Wire port adapter should use standard wrench uniform force tighten, not with afterburner rod afterburner slide wire to make the union, slippery edge and fracture, and to regularly check, in order to avoid causing loose off the plate or seepage.
3. taking into account the problem of aging of rubber products, so in sunny outdoor or wind pipe should build shade frame, non-exposure, rain, wind erosion is necessary.
4. Before installation, the pipeline must be based on the operating pressure, connections, media and the amount of compensation to select the right model, the number of noise displacement according to the requirements of selection.
5. Note the pressure regulator, when a momentary pressure and the conduit should be greater than the operating pressure is higher than the working pressure of a selection of gear joint.
6. Note that reusable hose fittings under pressure in the first, for example, after installation or long-term disabled before compression is enabled again, it should be re-pressurized and tighten the bolts again put into operation.
7. attention to its temperature regulation, normal for the media is 0-60 degrees Celsius temperature in ordinary water, special media.
8. When the pipe displacement greater than or equal to the maximum amount of compensation joints, should increase the number of joints to parallel displacement, non-tolerance in order to adjust the pipeline, in flexing the joint displacement and deviation from state limit, but can not exceed the limit .
9. The top water or floating water pipes should be fixed in the hanger bracket or anchor shelves and does not allow the joint to bear its own weight and axial force pipeline, or joints should be equipped with anti-pull-off device.
Accordingly, since the hose connector has a good overall performance, it is widely used in chemical, construction, water supply, drainage, oil, light and heavy industrial development in different areas, fire, etc.

omnipresent hose crimping machine

Hose crimping machine is all metal connector supporting force exerted by hose crimping machine shut female swivel fitting mold firmly withhold its support on the rubber hose. Hydraulic rubber hose assembly has been a lot of other industries have widely adopted almost everywhere. Use face increasingly wide hose crimping machines , demand is also increasing . So now not only requires hose crimping machine with high precision, high efficiency , and can withhold a variety of forms , wire diameter and various layers of the elbow, flange, high pressure, large diameter hose assembly. So the hose crimping machine made ​​more stringent requirements.
Hose crimping machine is a tube assemblies for hydraulic crimping device , it will by supporting the contractile force exerted by the metal connector hose crimping machine mold , the metal connector firmly withheld in the supporting construction machinery with high-pressure tubing or car on the brake pipe , oil pipe , air conditioning tubes, power tubes . Hose crimping machine is suitable for all types of machinery high and low pressure tubing, pipe , plumbing , cable connectors, automotive air conditioning pipes, power steering pipe , oil pipe , gasoline for tubing, and construction accessories , household hot water pipe withhold , widely used in vehicles, engineering machinery , hydraulic machinery , welding equipment and ferrule pipe fittings other industries.

jic female swivel fitting leak prevention

In the hydraulic system, both the metal pipe fitting, hose fitting, or are prone to leakage problems. For card sets of pipe joints,jic flare fittings mostly due to the pipeline by a larger force or impact, so that the card sleeve loose or pipe end surface deformation caused by leaks, you should check whether the card sets out of round,jic nipples edge or without defects, whether the pipe ends in good condition and the extent of compression ferrule nut, but also eliminate the pipeline force. For flared fittings, mostly due to excessive flaring, substandard quality requirements or repeatedly demolished, resulting in flaring deformation or cracks caused by the leak, this time jic female swivel fitting can be re-flared front amputated.
