Pipeline Valves
There are mainly two pipe flange standards used for important pipe connections at home and abroad: European DiNstandards and American ASME B16.5 and B16.47 standards. The producls in the same system standards can basically bematched with each other, but in different systems cannot be matched.Fasteners for valves are an important part of the pressure pipeline system. Bot-type fasteners are mostly used for flangeplates, When the tension is large, single-head bolts are easy to break at the connection of screw. So, they cannot be usedon medium and high-pressure flanges. Double-end studs can not only be used on medium and high- pressure flanges, but also be easily tightened from both sides.
RECOMMENDED MATERIALS: 304,316,316L,660
RECOMMENDED PRODUCTS: Double-end stud, Thread bar, Hex flange nut, Chemical nut, Heavy hex nut, Hose clamp, Hose plug
Rail Transit
Because of their functional characteristics, bridges and tunnels often play a role in construction projecls such as crossingmountains, crossing rivers and seas and penetrating natural cuting. High strength and corrosion resistance of fasteners arereguired in such occasions. The fastener products with high corrosion resistance materials are applicable to variousunderground and marine environments with high alkalinity and high acidity.
RECOMMENDED MATERIALS: 316, 316L, 2205, 321
RECOMMENDED PRODUCTS: Pentagonal bolt, Hoop bolt, M30-M80 series bolt, nut, stud
Aerospace
Because of the particularity of the use occasions, aviation fasteners should have higher anti-loosening requirements than onthe ground apart from the basic performance. They should also meet the reguirements for maintenance and replacementBesides, aviation fasteners should not only be anti-loose but also anti-lock. in addition, due to their highly integrated processdesian, the aviation fasteners should be suitable for assembly and use in narrow environments.
RECOMMENDED MATERIALS: 304, 316, 316L, 660
RECOMMENDED PRODUCTS: Hexagon socket head cap screw, Hexagon socket countersunk headscrew, Half-round head rivet, Nylon lock nut
Nuclear Power Energy
Due to the dense distribution of its core, photovoltaic panels are high integrated. The commercial and civil smallscalepanels are mostly installed on the roof of the top floor with narrow space, especially on the roof of the factory , which makespeople select fasteners that are suitable for narrow environments and easy to remove and replace when instaling theequipment.At the same time, the selection of fasteners should also vary according to different regions. For example, the requirementsfor corrosion resistance of fasteners in the rain environment in the south are the same as in the dry environment in the north.
RECOMMENDED MATERIALS: 304, 304L, 316, 316L
RECOMMENDED PRODUCTS: National standard (GB) hexagon bolt series, Hexagon thickened nut, Chemical nut, Double-end studNational standard (GB) thickened nylon lock nut
Communication Technology
Communication industry is a representative of high automation. The large-scale application of mechanical arms has madethe advantages of the assembly mulliple times higher. Mechanical arms have changed from grasping screws, spring washeland flat washer separately to grasping assembly at one time, which has greatly improved the production efficiency infactories.At the same time., due to its communication design characteristics, the demand for low-magnetic and non-magnetic productsis far higher than that of other industries; Most products need surace treatment such as dacromet and cellulose coating toreduce the interference of the environment on the products.
RECOMMENDED MATERIALS: 304, 316, 316L
RECOMMENDED PRODUCTS: Hexagon head assembling bolt, Cross recessed assembling screw, Hexagon socket head capassembling screw, Machine assembling screw, Machine screw, Torx screw, Hexagon socket head capscrew, Set screw
