SIX ADVANTAGES OF ROLLED
1). Increased Resistance to Leakage.
Much better surface roughness on thread and 100% perfect thread
tooth profile at full length of the thread greatly improve the
matching between male and female threads, which reduces leakage
possibilities with lathe cut nipples.
Zinc coatings remain intact plays “hard metal sealant” role in
enhancing mating of male and female threads, together with
traditional “soft tape” sealant.
Stronger mechanical property gives much more reliable and safety
connection during vibration of the piping system, like
2). Increased Rust Protection & Increase Durability.
Thread rust resistance is greatly increased with Rolled Thread
Original zinc coatings are not "cut away" as with lathe cut
Rolled (compressed-formed) thread increases the density of the
Original zinc coatings remain intact with higher density of Rolled
Thread Nipples, no doubt, increases its life, strength and
3). Safety and Improved Earthquake-Resistant strength.
Heat generated by lathe cut threads along with tooling, cuts and
tears at the metal, diminishing the pipes original strength.
Rolled Thread Technology adds strength to the metal product.
Increasing Bending Strength, Increases Tensile Strength, Increases
It is stronger than the original pipe itself.
Lathe cut threads tear at the bottom of the "v" grove and vary with
Rolled Thread Technology produces a uniform thread formation adding
40% - 60% to the thread groove, adding strength and eliminating
loose fit, sediment buildup at starter threads, drift and lateral
displacement of the piping under stress.
4). High Quality at Low Cost.
CPK ( Complex Process Capability Index ) values of rolled
threads are greatly increased.
Lower Labor costs to install:
* Reduced friction decreases installation time and call backs to
* Zinc coatings remain intact during threading offering greater,
long term protection.
Pipe sealant and tape requirements are reduced greatly on different
size pipe connection.
5). Increased Working Pressures.
PCFS (Chi-Thread) Rolled Thread Nipples offer increased working
pressures within pipe network. Rolled thread of the
pipe is, at least, as strong as the pipe itself.
6). Environmentally Friendly.
Unlike Waste bi-products produced by antiquated thread cutting
machinery, Rolled thread machinery produces no shavings, scrap
waste. Waste thread cutting fluids produced by thread cutting
machinery are eliminated with Rolled Thread Technology.
Global benefits of Rolled Thread Technology will mirror increased
working pressure capabilities.
