What is brass elbow tee coupling fittings

Brass elbow tee coupling fittings, including brass elbows, brass tees, brass coupling, are brass machined parts used in water or gas system, to change the flow directions or distribute flows. Brass elbow is design in 90 angle degree to change the flow direction, is frequently used brass fittings in pipe system.

Applications of brass elbow tee coupling fittings

Brass elbow tee coupling fittings are applied to connect pipes and control devices such as brass valves, the brass fittings are easy to repair and replace it's necessary components to pipelines for water, oil, gas and heating system.

How to select brass elbow tee coupling fittings

The selection of brass elbow tee coupling fittings depends on the requirements of applications, brass elbows are to change flow direction by 90 degree, brass tee fittings are to distribute the flow into two directions, brass coupling are to connect two pipes quickly such as radiator system. It's also import to select the brass material type for different markets, HPb57-3 and CW617N brass for European market, C37700 brass for American market.

How to install brass elbow tee coupling fittings

1. Before installing brass elbow tee coupling fittings, clean and remove any objects from the pipes.

2. Roll the brass elbow tee coupling fittings with PTFE tapes.

3. Make sure the fittings and the pipes are aligned.

4. Tighten the connections with spanner.

Chemical compositions we use for brass elbow tee coupling fittings

Brass elbow tee coupling fittings are mainly produced with brass HPb57-3, HPb58-3, HPb59-1, HPb59-3 in China, which are also workable for most customers abroad, HPb57-3, also name as China Normal brass, a variant of CW614N brass, is a local industry standard, with little Fe contents in composition, and lower costs than CW614N. It’s widely used as a standardized material in China and accepted by most global markets and customers. HPb59-1, has less Fe, Pb and higher price costs, it’s more used for high-quality products or market, such as brass fittings for USA market.

Surface treatments of brass elbow tee coupling fittings

Brass elbow tee coupling fittings surface treatments includes rough brass color, nickel-plated, chrome-plated and acid-washed.

They have different function for applications.

Rough color is brass elbow tee coupling fitting body sandblasted and without plating.

Electroplating (nickel-plating and chrome-plating) can enhance the corrosion resistance of brass elbow tee coupling fitting, increase hardness, prevent abrasion, improve conductivity, smoothness, heat resistance.

How we produce brass elbow tee coupling fittings

Brass elbow tee coupling fittings are produced in 8 main steps:

1. Brass raw materials are bought from local suppliers in forms of brass bars.

2. Brass bars are cut into smaller pieces with different sizes according to order requirements

3. Brass elbow tee coupling fittings are hot forged to make rough bodies.

4. The rough bodies are trimmed and cut off unnecessary parts.

6. The rough brass elbow tee coupling fitting are machined by CNC machinery.

7. The machined brass fittings bodies are nickel- or chrome-plated.

8. The Brass elbow tee coupling fitting are ready for delivery after final finished goods quality inspection.

How we pack brass elbow tee coupling fittings

Brass elbow tee coupling fittings package provides good production during transport.

We pack brass elbow tee coupling fittings in small inner boxes, then put into outer cartons, finally load in wooden pallets.

It will protect the goods well and can avoid damages and wet.

We also pack as per customers' OEM designs.

How we test brass elbow tee coupling fittings

Brass elbow tee coupling fittings are professional tested and inspection in our lab:

Equipment include material spectrometer analyzer, flow rate tester, torque tester, body resistance tester, endurance tester, high-low temperature tester.

These equipment enable us to analyze threaded brass fittings material compositions and type tests according to related standards, ensure our Brass elbow tee coupling fitting are correctly designed and produced.
