Quality Products

HydroPro designs, manufactures and sells its own line of hydraulic tube expansion equipment and related products tailored for use in the heat exchanger and boiler fabrication and repair markets.

ATTENTION HydroPro Inc. has developed a new system and tooling that sets the tube protrusion, centers the tube and locks the tube in the tubesheet hole, while leaving small air gaps that allow an escape path for weld gases during the welding process. This tooling was designed to meet the needs of customers using orbital welders to weld their tube-to-tubesheet joints. The WeldLock system and tooling can also used to set tubes when utilizing manual welding procedures.

What is Hydraulic Expansion?

Hydraulic expansion is the direct application of a high internal hydraulic pressure within a tube or sleeve in order to form a tight joint between the tube and the tubesheet or a tight seal between the sleeve and the tube. Specifically, high pressure water is captured inside a tube but within the tubesheet. As pressure increases the tube goes into plastic deformation until it makes contact with the tube hole. Additional pressure stresses the ligament but always within the ligaments elastic range. When pressure is released the result is a tight interfacial fit between the O.D. of the tube and the I.D. of the hole.


Why Hydro-Expand?

There are four main benefits to hydroexpanding

  1. No stepexpanding – Any thickness of tubesheet can be expanded in one quick operation.
  2. Minimal work hardening of the tube material during expansion means that even difficult tube materials such as titanium or superduplex stainless can be easily expanded successfully.
  3. Less wall reduction and less stress concentration from the expanded to the unexpanded portion of the tube results in longer tube life.
  4. Improved quality – each tube expansion is controlled by the system parameters and not influenced by the operator.

Why Choose HydroPro?

HydroPro continues to be the world leader in Hydraulic expansion technology, systems and tooling. HydroPro is totally committed to provide our customers technically superior, cost effective products and services in a timely manner.

CAR-BER Testing

Products & Services

Hydrostatic Isolation Tool

The CAR-BER hydrostatic isolation system safely isolates downstream areas, where “hot” work is in progress, from potentially hazardous materials upstream of the work area and safely diverts such materials off-site and “out of harm’s way”. The hydrodynamic features of the CAR-BER isolation system prevents the transfer of heat from the downstream work area to the upstream portion of the pipe thus reducing the amount of toxic materials (hydrocarbons etc.) released from the upstream portion of the pipe – no exposure to serious health hazards! and; in the case of explosive materials, eliminating the possibility of explosion – no ball of fire!

Hydrostatic Weld Test Tool

The CAR-BER hydrostatic weld testing tool can be inserted into the open end of a flange, pipe or tube; centred over the weld to be tested and pressurized with relative ease (the tool is light in weight – no cranes or specialized lifting equipment required) and with a safety factor that is compromised only by the workplace environment and/or the personnel conducting the test. The CAR-BER test tool by itself; the methodology to testing; as well as the volume of medium; offers no threat to safety and/or environment whatsoever.

Split Frame Clamshells

12-inch-severH & S Tool

U.S. Patent #7,690,238 Awarded for Motor Mount Design!

Watch The Short Demo Video

1″ – 56″ (25.4 – 1422.4 mm)

The AFC series of split frame clamshells has been developed with the direct input of field machinists to create the premier machining tool to sever, bevel and square tubes and pipes from 1″ to 56″ O. D.

These unique tools have patent-pending features such as bearing design, safety tripper mechanism and motor mount. The low- clearance design utilizes locator pads with a full 3/4″ (19.1 mm) adjustment. This is double what others offer and dramatically reduce the number of extensions required for the full range of the model.

Strong and Rigid

Each of our 18 models are strong and rigid for durability and amazing machining accuracy. These tools are engineered to minimize weight and ease handling and alignment.

Smooth, reliable power is delivered by pneumatic, electric and hydraulic motors. We have eliminated the need for extra motors and conversion components when swapping from one motor type to another. The only ones available like this.

2″, 4″ and 7″ tool slides, an out-of-round tool slide, front and right-angle motor adapters, counter bore heads and a full compliment of the highest quality, resharpenable cutting tools round out our list of productivity – improving accessories.

After years of research and discussions with field machining professionals, H&S Tool introduced these advanced split-frame O.D. mount pipe machines in 2009.
These tools have quickly become the preferred choice for severing, beveling and squaring pipes from 1″ to 56″ O.D. (25.4 to 1422.4 mm). The AFC series covers sizes from 1″ to 42″ (25.4 to 1066.8 mm). Our heavier duty BFC series starts at 48″ (1219.2 mm).
Greater reliability is realized with our heavy duty gear box featuring the patent-applied-for outboard bearing and patented pocket-mounting to the body. Strength, rigidity and reduced weight are accomplished with our aluminum frame. Lower overall investment is required due to our unique locator pad full 3/4″ (19 mm) travel adjustment which reduces the number of extensions needed to cover the full range and our complete non-size specific parts interchangeability across the full model line.
Rental or purchase, the machines are loaded with time-saving, work-saving, profit-building features that are not available on any others.
clamshells-4The patent-pending tripper mechanism has been designed for safety and ease of use. The extended handle for engagement and disengagement keeps hands clear of rotating components. clamshells5Maximum reliability is assured with the patent-pending gear box that features a front bearing to support the motor drive shaft, the patented pocket mount and our patent-pending ring mounted bearing design.
clamshells-6The precision machined aluminum frame delivers rigidity and minimizes weight without compromising strength. clamshells-7Unique to H&S, our locator pads have a full 3/4″ (19 mm) travel adjustment per pad which minimizes the number of pads required to cover the full working range.
clamshells-8The entire line of H&S split-frame O.D. mount machines was designed for parts interchangeability. Non size-specific parts are common from the smallest to the largest model. This reduces the amount of parts inventory required and allows swapping from one machine to another in the field in the event of a malfunction.

Bevel, square, sever and perform many other machining projects for individual and in-line tubes and pipes – powered by pneumatic, electric and hydraulic motors.
