When selecting threaded plumbing fittings, knowing the intended application is essential. The pressures, environmental conditions, and safety requirements for a residential water line are very different from those in a high-rise commercial building or a heavy-duty industrial pipeline.
At JIANZHI, we design and manufacture fittings with the versatility to meet diverse project needs—whether for home plumbing, commercial facilities, or large-scale industrial systems.
In residential settings, threaded fittings are valued for:
▷ Ease of installation – no welding or special tools needed
▷ Maintenance convenience – fittings can be replaced without cutting the pipe
▷ Leak prevention – precision threads ensure a secure seal
● Potable water distribution systems
● Home irrigation and sprinkler setups
● Gas supply lines for kitchens and heaters
JIANZHI provides corrosion-resistant, FM/UL certified fittings to ensure safety and compliance in home installations.
Commercial projects, such as office buildings, hotels, shopping centers, and hospitals, often require:
▷ Higher pressure ratings to accommodate taller structures and complex plumbing networks
▷ Durable materials that handle frequent usage and maintenance cycles
▷ Certified safety compliance for systems like fire sprinklers
● Fire protection systems (FM/UL certified)
● Central HVAC water and refrigerant lines
● Compressed air piping in service areas
Our heavy-duty plumbing fittings are engineered to meet these demands while ensuring cost efficiency for contractors and project owners.
Industrial facilities—factories, power plants, oil & gas sites—demand fittings that can perform under extreme conditions:
▷ High pressures well above residential and commercial standards
▷ Resistance to corrosion and abrasion from chemicals or high-temperature fluids
▷ Long service life to reduce downtime and maintenance costs
● Process water and steam pipelines
● Oil and fuel transfer systems
● Chemical transport and storage facilities
JIANZHI heavy-duty threaded fittings are tested to withstand high PSI ratings and meet the strict requirements of industrial safety standards.
When selecting a fitting for your application, consider:
→ Pressure rating – match to the system’s working pressure
→ Material – malleable iron, stainless steel, or brass, depending on fluid type
→ Certification – FM/UL for safety-critical systems
→ Thread type – NPT or BSP to match local standards
Our technical team can help you match the right threaded plumbing fitting to your project’s specific needs.
No matter if you are upgrading a home water system, installing a commercial fire protection network, or building an industrial plant, JIANZHI delivers fittings you can count on—certified, pressure-tested, and built to last.
