Pipe Mills

DynaIndustrial Advantages:

• Direct couple and through bore design for drive systems on V-rolls increases the simplicity of the system.
• For heavy duty vibration or pipe misalignment applications, DynaIndustrial has a foot mounted drill design.
• Drop-in modular design built on own sub-assembly allows for ease of install and removal.
• For 2-3/8” to 24” diameter pipe, DynaIndustrial utilizes let down blades and kick out blades that are on a single pull rod designs that are activated by hydraulic or pneumatic cylinders. Only one cylinder is needed to actuate 6 flags! Less moving parts and simple design means reduced maintenance downtime.
• All mechanically timed.
• Quick cycle time matches line speed.
• Telescoping leg weldments on the main frame, enables the level of elevation to be set during field installation.
• Conveyors are all prewired and pre-plumed to common junction points.
• The conveyor/gravity skid design is build for longevity with heavy duty wear plates.
• With DynaIndustrial’s adjustable stop design, pipe size can be adjusted quickly by a turnbuckle at the end of the conveyor.

DynaIndustrial was awarded a contract to supply a Rotary Plasma Cut-Off Unit to a large diameter pipe manufacturer. In this particular case the end user was positioning a manual cutting system on the pipe each time a pipe had to be cut. The process was difficult and time consuming.

DynaIndustrial supplied a standalone plasma unit that could easily be installed with minimal modifications to the existing pipe conveyor.

Prior to building this unit DynaIndustrial had supplied multiple units for a variety of applications in pipe making. The applications varied from in-process pipe parting to pipe test sampling to pipe reclaim. In some cases, units were supplied to eliminate problematic bandsaws or rotary carbide tip cut-off units.

Typically, each situation required customization due to available envelope constraints and or customer requirements. Units are designed with ease of operation and maintenance in mind. Typical specifications are outlined below but as stated, customization is common.

Technical Specifications—Plasma Units:

Pipe Cutting Ranges: 2” to 12” diameter, 8” to 24” diameter, 30” to 72”diameter
Pipe Thickness: .188 to .75 inch
Control: Local or Remote
Fume Containment: Optional

DynaIndustrial Advantages:

• Maintains control and back tension
• Eliminates lap to lap gauling or scratching, coil spring and surface imperfections

The main benefit of our uncoiler is the ability to maintain control and back tension on the strip as it is being paid out. By maintaining back tension on the strip we eliminate lap to lap gauling or scratching. This can significantly reduce down grades and post processing of pipe, saving money and increasing prime yield.

Our uncoiler also eliminates coil spring when the bands are cut. By containing the coil while it is being threaded up to the butt weld we eliminate surface imperfections by controlling and preventing unwanted coil spring or unwinding.

Coil cars are an integral part of many pipe and steel making facilities. DynaIndustrial has experience with coil cars used in slitter lines, coil prep lines, spiral mills, ERW mills, cut to length lines and many others. Our designs focus on preventing damage to the coils and coil containment, being extremely robust and easy to maintain. We have dealt with many issues of surface scratching and lap to lap gouging and scratching. We will use this extensive experience to solve your coil car and coil handling problems.

Side guides are used in many steel processing facilities from cut to length lines, slitter lines, spiral mills, ERW mills, etc. Their primary function is to control the strip while other cutting, edge milling, forming or other processes are being done. DynaIndustrial’s side guides are extremely robust and easy to maintain. Any of the surfaces that come in contact with the scalp are easy to maintain. The side guides are available in various widths to suit your needs.

As with any piece of DynaIndustrial’s equipment it is designed to last in the extremely harsh environment of steel processing facilities.

DynaIndustrial has built weigh measure stations to provide final tally on outgoing pipe indicating weight, length and labelling with painted stencils, pin stamping, or color banding as required. This ensures accurate tracking of outgoing products. This system can be integrated with pipe tracking software.

We utilize a human machine interface (HMI) screen to allow for ease of operator interactions with the machine.

It also comes equipped with an integrated diagnostic interface.

Many pipe casings require testing to failure from external pressure. This can involve extreme pressures and forces to collapse pipe from external pressure. These tests require extremely highly engineered equipment to withstand the forces places upon them. DynaIndustrial has a range of vessel sizes and pressure ratings to achieve these tests; vessels up to 16’ long, 16” bore and up to 30,000 PSI.

Not only do we have these extreme pressures vessels but they have been redesigned for quickly loading and unloading test samples.

Our monitoring system records the pressure curve of when the pipe collapses and fails.
