Rolled pipe threads have several advantages over cut threads:
1. Rolled threads provide a perfect thread profile and excellent surface, enhancing the mating between male and female threads. The original zinc coating is kept intact, providing better corrosion resistance.
2. Testing showed rolled thread connections could withstand pressures up to 17kg without leaks, even after fracturing during tensile or bending tests. The connection remained intact and leak-free.
3. By not cutting away material, rolling increases the pipe's density and mechanical properties. Testing found tensile strength of rolled connections was 54.2kN compared to 41.65kN for plain pipe. Rolled threads can replace heavier Schedule 80 pipes with lighter Schedule 40
This document discusses design guidelines and best practices for producing zinc diecastings for electroplating. It provides rules for minimum radii, recessed features, hole sizes and spacing to improve platability.

100% Perfect Thread Teeth Profile – Excellent Teeth Surface Enhance Mating – Zinc Coating Kept – More “Thickness” of Pipe.
2. Excellent Rust-Resistance on Rolled Thread Pipe
1.Original hot-dip zinc coating of the galvanized pipe remains intact, and is not cut away as with lathe cut ones.
2.The density of the rolled thread pipe is increased greatly and makes, at least, the “same thickness” as the original pipe
itself, and forms an anti-oxidization layer of high metallic density against rusty.
3. Pipe Material Not Cut Away Makes Thread Mechanical Connection Much Better
The mechanical properties of the pipe thread are greatly improved as no material is cut away and the weight per unit length of
rolled thread pipe remains unchanged, and further more the metal density is increased.

5. 1.1 Perfect Thread - Enhance Mating – Zinc Coating Kept – More “Thickness”
1.1.1 . Perfect Thread: 100% perfect teeth profile (geometry size),
produced by long-life rollers (tools), fundamentally guarantees the
excellent integrity with female cut thread. The cut teeth, by easy-
worn knife (tools), varies in profile time to time, can’t guarantee it.
1.1.2 . Excellent Surface Enhance Mating: Surface roughness of
rolled thread is improved dramatically by 5 – 7 levels to Ra < 0.4
due to the thread to be formed by the roller rolling on the pipe, and
the cut thread is by, knifing in the pipe, Ra > 3.2. Rolling makes
much better mating between the male and the female thread. Rolled Thread Cut Thread
1.1.3 . Zinc Coating Kept: Rolled thread of galvanized pipe is sealed mainly by original zinc
coating which is metallic layer (hard) sealing & very good for suffering the weight of the pipe,
plus traditional tape(soft) sealing. And the cut thread is sealed 100% by tapes(soft) which are un-
appropriate for suffering the weight and can’t be 100% sure for lasting a period of years.
1.1.4. More “Thickness” of The Pipe: As no material is cut away, the weight per unit length remains
same, plus a rolled teeth surface is much harder, those bring improvement in mechanical properties.

Mechanical properties of the cut
thread is lower than the original pipe by 30% - 50%.
The cold rolling process doesn’t cut the metal fiber off,
instead the rolling compresses the metal fiber and make
it stronger. Therefore the strength of tension, bend,
shear and fatigue are increased, as well as the surface
hardness. Chi-Thread nipples act very good mechanical
connection performance, and could protect the piping
system well from subsidence, drift and lateral
displacement & etc. under stress.

20. 3.7 Rolled Thread Nipples Almost Double The Maximum Working Pressure
The calculations are quoted from the Wheatland Tube Company U.S.A. and it shows that the pipe
after cutting thread significantly decreases the max. working pressure by 32% - 57% on different
size and wall thickness of the welded pipe. In other word, as per previous information in this PPT, the
pipe after rolling thread will not reduces the max. working pressure, and in another word, under same
condition, we can save a huge (12% up) pipe material if we use the rolled thread on the pipe.

¾” NPT Cut Thread Steel Nipple Sch. 80
Take the ¾” DN20 Sch.80 Cutting Pipe Thread as an example:
The ¾” NPT teeth height is 0.057inch(1.45mm) + The taper (1:16) loss is from0.006 – 0.021inch, therefore after cutting,
the original nominal wall thickness was cut off and varies from the min. 0.076inch / 1.93mm (0.154 – 0.057 – 0.021) to
the thickest 0.091inch / 2.295mm (0.154 – 0.057 – 0.006). The thickest after cut thread is only 0.091inch (2.295mm),
19.47% less than the Sch.40 one and the max. working pressure is only 1150 psi as per the calculations last page.
Take the ¾” DN20 Sch.40 Rolled Pipe Thread as comparison:
The weight (mass) per unit length after rolling (the wall thickness is rolled and compressed) is same as the plain end
pipe itself. i.e. the max. working pressure is 1450 psi as per the calculations from Wheatland Tube Co., last page.
The max. working pressure of rolled thread ¾” DN20Sch40 pipe or nipple is 26% higher than the cut one of Sch80.
And at meantime we can easily get the material saved by 0.35 lb/ft ( =1.48 -1.13 ) or 24% ( = 0.35 / 1.48 ).
