FAQ

Q:Are there different types of copper fittings
A:Here are copper end feed fittings, copper press fittings, solder ring fittings, ACR copper fittings, brassl compression fittings, brass solder fittings, brass thread fittings and PEX fittings. These fittings are mainly used inl the plumbing, gas and ACR industry. According to the shape and functions, the copper fittings generaly includes Copper Elbows, Copper Tee, Copper Coupling, Copper couplng reducer, Copper adapter, Copperl Union, copper trap fittings, copper end caps, crimp ring, Copper full cross over, Copper partial cross over, Ul bends and etc.

Q:What is a common copper fitting?
A:Copper end feed fittings are commonly used copper ftting, which are made from copper and require a soldered joint to connect pipes together. The pipes-to-be-joined are inserted into the ftting, which is heated.l Solder fis the small gap between pipe and ftting, sealing and making a strong jaint which is resistant to pulingl and rotation of the pipes. This type of ftting requires that solder wire must be melted and fed into the joint as it isl heated. Copper end feed fttings are sim and neat, inexpensive, and form astrong joint between pipes. They arel probably the most reliable too for use in wals, under floors and other inaccessible locations as the jaint is morel secure and less likely that pipes will separate or O-rings deteriorate, resulting in leaks. However, they are morel difficult to use, and since the ftting must be heated using a blowtorch, there is always the danger of fire. Also,l preparation of pipes and ftting is essential, and these must be cleaned with wire wool so that solder flows andl coats all the surfaces being joined.

Q:Can custom products be produced?
A:We support custom copper in different sizes, designs and finishes.

Q:Can you provide samples?
A:Yes, we can provide somples for free, but need buyer to provide shipping cost. Also can provide customizedl samples according to your drawing, sample charge can be refunded when bulk order released

Q:How to calculate the weight of a copper tube?
A: (Outer diameter-Wall thickness)"Wall thickness O.O28 Length (m)-Weight kg)

Q:How to you calculate the weight of a brass rod?
A:Weight (a=nd2/418.4 where d is the diameter (mm) and lis the length (m))

Q:Why is tin plating applied to copper busbars?
A:Tin is an excellent soldering material, which enhances welding performance. Additionally, tin plating on copper busbars improves their electrical conductivity, heat dissipation, and corrosion resistance.

Q:What are the differences between copper fittings and brass fittings?
A:Copper fittings and brass fittings differ in material composition, properties, and applications. Copper fittingsl are made from pure copper, offering exceptional electrical and thermal conductivity, making them the preferredl choice in fields requiring specific material properties, such as water lines, medical applications, gas transmission,land heat exchangers. On the other hand, brass fittinas are made from a copper alloy containing zinc, which not only retains the excellent characteristics of copper but also significantly enhances strength and hardness due tol the addition of zinc. This makes brass fittings highly adaptable and durable, and they are widely used in plumbing systems, automotive manufacturing, and various mechanical equipment.

Q:What are the differences between continuous cast brass rods and extruded brass rods?
A:Continuous cast brass rods and extruded brass rods differ in production processes and properties. The formerl is produced through liquid cooling and solidification, resulting in high strength and good electrical conductivity.l making it suitable for electrical components. The latter is obtained through the extrusion process, offering excellent plasticity and workability, and is commonly used in precision machining applications. Each has its ownl advantages in terms of cost and application.
