Hose assembly in the fluid industry is an important pressure pipe components, it bears many important functions. But in reality, many people have some misunderstandings, and even some people think that a treasure to buy a fitting, rent a home-made press, a half-day worker training can be on the job. In fact, the production of hose assembly requires a wealth of theoretical knowledge, sophisticated production equipment, professional staff, take you to see how Hainar to provide customers with high-quality hose assembly.
1.A wealth of theoretical knowledge
We all know that a hose assembly usually consists of three parts: the hose, the connector, and the clamp or ferrule (a Push-on may not require a clamp) . Hose barb and other structures are usually designed in the part of the inserts and sleeve which is in contact with the Hose, so that the fittings can form good friction with the Hose, and ensure that the joint can bear enough end force in the process of using.
End Force:
What is the End force? In this case, the end force is the kinetic energy acting on the end in an axial direction. This force is the force provided by the clamp to prevent the joint from detaching from the hose. Junior high school physics tells us that pressure = pressure x cross-sectional area (f = Px s) , pressure is what we usually call the working pressure of the hose (pressure is actually wrong, but we have been used to it) , the cross-sectional area is the cross-sectional area of the inside diameter of the hose. Look at the table below:
For example, a 1-inch hose with 100 psi (7 bar) ends at 79 pounds (36 kg) , but a 6-inch hose with 2,827 pounds (1,282 kg) ends at the same working pressure. Imagine how serious a problem it would be if a connector flew out of use.
Factor of safety
The above formulas and tables only tell us the lower limit of the bearing capacity, but we have to consider certain Factor of safety, in the joint design, Factor of safety is commonly used data. Therefore, the end force of a connector actually needs to be multiplied by 4 on the basis of the above table.
Buckle value
We strictly in accordance with the American Rubber Association standards, combined with their own development of the joint and sleeve, through a series of calculations, get accurate buckle value.
2.Precision production equipment
As the saying goes: if you want to be good at something, you must first sharpen your tools. In modern industry, it is impossible to produce high-quality products without excellent equipment. In recent years, the company has introduced Finn-power,UNIFLEX in addition, the company is also equipped with a variety of imported small professional measuring equipment.
Crimp machine
press parameters are measured in millimeters, accurate to two decimal places. The company requires a tolerance of ± 0.25 mm for the values and theoretical values, but most of the equipment in this industry doesn’t have a tolerance of ± 0.5 mm.
Test equipment
Test bench can be completed blasting test and assembly pressure test.
Blasting test
Development of any new connector to be subject to the blasting force test, 4 times the working pressure, the joint can not have any deformation or escape from the pipe, otherwise the joint even if not qualified. Assembly pressure test: The Factory Production Assembly according to the actual use of working conditions and customer requirements, targeted completion of the assembly pre-factory pressure test. The hoses tested are required to be 100% qualified.
3.Employees with professional skills
Employees are the core intangible asset of the company, and professional technical engineers and skilled operators are key factors in ensuring product quality. At present, the product department of Hainar Company has a bachelor degree or above, and has more than five years experience.
After reading these, I believe you have the basic ability to evaluate a hose assembly manufacturer, but this is the tip of the iceberg, only with the professional assembly manufacturers, to avoid the worry.
