Applications of Pipe Nipples

Plumbing Systems

In residential, commercial, and industrial plumbing, nipples are essential for connecting pipes, extending lines, and joining fixtures like faucets, showers, and toilets. They are used with various pipe materials, including those compatible with malleable iron pipe fittings and grooved pipe fittings.

HVAC (Heating, Ventilation, and Air Conditioning)

Threaded pipe nipple play a crucial role in HVAC systems for connecting pipes that transport water, steam, or refrigerants. Their reliability is vital for maintaining system integrity and efficiency.

Fire Protection Systems

In fire sprinkler systems, pipe fittings nipples are used to connect sprinkler heads and pipe sections. The secure connections provided by nipples, especially when used with robust systems like those involving grooved pipe fittings, are critical for the dependable operation of these life-safety systems.

Industrial Piping

Various industrial processes rely on nipples for fluid and gas transportation. This includes applications in manufacturing plants, chemical processing, oil and gas industries, and power generation facilities. The choice of nipple material and type often depends on the specific demands of the industrial application, including pressure, temperature, and a corrosive environment.

Casting and Metallurgical Testing of FURDFITTINGS™ Fittings

The chemical composition of the material of the horse malleable iron pipe fittings and groove fittings determines its mechanical properties. Strictly controlling the pouring temperature, pouring time, iron weight measurement and other measures can ensure the organization and properties of the material. The company adopts advanced means such as spectral analyzer, pre-furnace molten iron rapid analyzer, molten iron temperature tester and so on to test the smelting process.

Pipe fittings material mechanics experiment

FURDFITTINGS™ conducts mechanical property testing of metal products on various pipe fittings to conduct comprehensive tensile, compression, yield, and elongation tests on samples of bolts and nut castings to ensure that the indexes are in accordance with the requirements of FM and UL standards.

Performance Tests of Rubber Fittings for Malleable Cast Iron Pipe Fittings and Grooved Pipe Fittings

The company’s rubber physical performance laboratory is responsible for testing the mechanical and aging properties of each batch of sealing rings, including Shore hardness, tensile strength, elongation at break, compression permanent deformation after hot air aging, and other indicators, meeting FM and UL standards.

Gas tightness test of pipe and couplings

The purpose of the gas tightness test is to check the sealing performance of the pipe fittings, gas penetration, gas tightness test can be exposed threaded pipe fittings in the existence of air holes, sand holes, to eliminate the leakage of hidden dangers.

Performance testing of grooved fittings with FURDFITTINGS™

The performance laboratory of grooved pipe fittings is established in strict accordance with the relevant requirements of GB5135.11-2006, EM and UL, and can carry out all the performance tests according to their requirements, including hydrostatic sealing performance, compressive strength, negative pressure sealing performance, bending torque, rotating bending torque, vibration, low-temperature resistance, fire resistance and so on. Ensure that every batch of grooved pipe fittings meets the requirements of the relevant standards.
