When deciding how to choose the correct pneumatic fittings for your application, you should examine the different materials that are commonly used in order to determine their different physical properties, gas compatibility, and reaction to, for example, temperature changes.
Aluminium fittings are commonly used for low pressure, low density applications where its low tensile strength is not an issue. It is a lightweight material and most often chosen for its resistance to corrosion, but can be alloyed with other metals to increase its strength and density.
Brass is also corrosion resistant, but much stronger and more durable, and it offers good conductivity and high temperature ductility. It is most commonly chosen for pneumatic fittings because of its excellent performance and machinability.
Although typically more expensive, stainless steel already has excellent corrosion and chemical resistance, with the durability and strength of ordinary steel.
Polypropylene is a thermoplastic that is widely used for pneumatic fittings, as it has high durability, low price and wide compatibility with other materials. It demonstrates excellent bi-axial strength, cold flow and yield elongation. It can safely be used for applications in exposed areas, because it is resistant to weathering, ozone and UV radiation.
Composites are fittings made from various material combinations, such as carbon, graphite and fibreglass. These materials are also used in applications requiring high chemical resistance and temperature durability; they have a high melting point as well as low thermal and electrical conductivity.
For specialised environments, enhanced fittings can be engineered with additional protections such as integral lining, surface coating or plating, or special insulation.

Dear friends and customers :
we come back to work from holiday. We thank everyone for your support and trust in the past years. I hope that in the new year, BLCH will continue to receive everyone's attention and support, and we , as always , provide better service to everyone !
GOOD-LUCK OF BEGINNING !
The design of pneumatic fittings should allow the free flow of required air or gas without any opportunity for significant drops in pressure. Pipes and hoses should be configured as simply as possible, so that no energy is lost in the air’s passage through the system. Always use straight runs wherever possible, and only use elbows and Ts if absolutely necessary.
When choosing your pneumatic fittings, there are some key environmental factors that must also be taken into account.
The operating temperature specified by the manufacturer defines the range of temperatures or the operational temperature ratings within which the particular fitting is designed to work. This is measured in degrees Celsius (°C) or degrees Fahrenheit (°F), and the fitting may well fail if it is made to operate above or below this specified range. It must be borne in mind that the ambient temperature of the inlet air to the compression unit will affect the compressed air output.
As air heats up or rises the pressure drops, so industrial automation equipment should generally only be used in a controlled temperature environment. In general terms, every 5º F of temperature reduction produces a 1% improvement in efficiency and power conservation, but both high ambient air temperature and low intake pressures will significantly affect performance. It’s also a fact that an increase in operating temperature will cause a reduction in the operating pressure of polyurethane and nylon tubing.
The most common air contaminants are water, oil and particulates, such as dirt, rust and metal shavings. Such contaminants in the air intake are commonly removed by the filtration system, usually comprising a filter-regulator-lubricator unit (FRL). The lubricant also acts as a coolant in some types of compressor, but there is sometimes a danger of the heated lubricant getting back into the inlet air and causing contamination there. Additional contaminants in the form of bacteria or microorganisms can also be critical in some types of application, such as pharmaceuticals or food.
It seems simple, but it is essential to ensure that there is sufficient space around the installation to allow the best configured construction, as well as access for maintenance and repairs. It should be large enough to allow pipework to run naturally, and to permit a free flow of ambient air so the space doesn’t overheat externally. The equipment also needs to be stable with no possibility of vibration.
Time is flying, in an instant, half a year of 2020 has passed. Enterprises and employees even all of the world have undergone a new test in the past six months due to the COVID-19.
In the beginning of 2020, affected by the epidemic situation, the company’s commencement date has been postponed again and again. With the support and one month’s arduous straggle of company’s leaders, company finally started operation on 22 February successfully.
In order to meet the supply needs of customers, we have been continuing to work overtime with quick respond to deliver high-quality products to customers.
The expert review meeting named “Internal Pilot Type Precision regulator” of Zhejiang manufacturing group standard, which was leading by our company successfully held in April.
Affected by the epidemic situation, the safety production monthly meeting of the company was held on May 4. But we have never relaxed our vigilance about safety in production.
On June 23, 2020, Ningbo Fenghua District pneumatic industry association youth branch held a salon activity in our company. We have exchanged many acknowledge with Yueqing and Fenghua’s ” HYDRAULIC-PNEUMATIC MAN” as well.
Even though the half year of 2020 is over, in the following six months, let’s keep going on with high enthusiasm for work.
WE PASS TOGETHER !
