We’d like to welcome Gregg Nichols to our staff. Gregg has a combined 28 years in Industrial Distribution & Manufacturing Operations and Sales.
His prior experience includes 5 years with Perfection Rubber (operations manager and sales), 18 years with MSC / Dolin Supply (team leader and outside sales) and 4 years with American producers (outside and industrial sales)
The business segments he previously focused on included:
Gregg’s areas of expertise include:
Hydraulic Hoses, Tubes and Fittings
Metal working – Machining – Hole Making
Material Handling (lifting and rigging)
Pipes, Valves & Fittings
Gregg has jumped right in and got off to a strong start. His outgoing personality and years of knowledge have been a perfect fit here at Riggs. Call him for a visit to your facility and see why he’s an invaluable asset to our team!
Used during repairs and outages, this simple looking device becomes a necessity. The Tube Plug is hammered or welded into the open section of pipes in boilers and heat exchangers. They plug the end of the pipe to either stop the flow of steam or coolant. If the plug’s seal is not tight the coolant can seep into the material and contaminate it.
What makes this seemingly basic item so important are a few factors. First, its fit must be right. Sure they are tapered, but they must fit without damaging the existing pipe or sliding too far in. Also, the material specifications for Tube Plugs can vary greatly. While some plugs can be made out a carbon steel like 1018, other plugs must match the existing pipe section (i.e. A350 with more carbon content) or even stainless steel, nickle or other metals. If the wrong type of metal is used, it could lead to corrosion, rust, leaks or a possible reaction with existing materials in the system.
Even the machining isn’t always as simple as it may seem. Bar stock in not always available in a size close to what the job requires or the material type needed is only available as plate. In that case, a plug larger than the finished size would be cut from the plate and then turned turn by hand on a lathe. Time consuming, yes, but necessary for a professional fit.
At Riggs Machine & Fabricating, we not only have the experience, but we ask the questions to make sure the job is done right, the first time. Don’t trust those supposed simple jobs to just any shop. Call Riggs first for the dependability and quality your facility demands.
The Auger Conveyor uses a rotating helical screw blade to move materials along its length. This unit moves abrasive materials from hopper to hopper then to bagging.
Notice how the abrasive material has worn down the blades. Also, material is sticking to the untreated blades. Material slides over the smaller, worn out blades making the conveyor ineffective. Jobs take longer and costs rise quickly.
This new unit has Hardfacing Wire (Lincore 55) welded to the blades to reinforce them and add durability. This surface resists sliding wear and mild abrasion. These new blades will have a longer service life.
If you ever wondered where the custom training equipment in industrial classrooms come from, then look no further than Riggs Machine.
At Riggs we can create custom pieces from scratch, like this “oil flinger” demonstration unit. Shown from conception, with 3D renders, to the final unit in the classroom.
And we also often disassemble, create “cut-away” sections, sandblast, paint and reassemble actual pieces of equipment to be used in working classrooms. These units are used for hands-on training before students hit the field. Much better than a video or book based lecture.
Some of these jobs can be more time and labor intensive than actual repairs! But we don’t mind. We’re proud to be part of the team who help educate the next generation who will be keeping our refineries, steel mills and factories running.
Blinds, sometimes known as blanks, isolate a section of pipe for repair, maintenance or testing. There are many types of blinds as we have shown before from the slip blind, the spectacle blind to the bleeder blind.
Here we have a nice assortment of Target Blinds. Used much like the bleeder blind, the target blind is placed on the end of a pipe section rather than in the center of a section. Gauges can be placed on the valves to test the pressure in the section of piping. Sampling can also be taken from the valve if desired.
The different sizes correspond with the different sizes of piping found within the refinery.
This group of target blinds is a bit “beefier” than usual. They will be used during the permanent shutdown of a unit until the demolition of the unit occurs. There may be need for occasional venting of the piping section until the demo.
Do you use long term scaffolding in place of permanent platforms? Are they stable, secure and up to the new OSHA regulations? Are you still renting your scaffolding and paying for it month after month?
FALL PROTECTION & SCAFFOLDING VIOLATIONS
remain among OSHA’s most frequently cited standard violations.*
OSHA violations are now subject to higher penalties,
this signals a 78% increase in penalty amounts.*
Convert your temporary, unstable scaffolding to a sturdy, permanent structure. No more rentals, no more repairs, no more guard rails that are dangerously low and above all, avoid the fear of those outrageous OSHA fines.
A Riggs Machine representative will review your current needs and outline the best options for your facility. We even offer 3D renders of the unit before construction begins so you can visualize the actual unit design.
Walkways – Handrail – Ladders
Riggs can not only deliver new assemblies for your facility, but update your existing equipment to bring it up to the new standards.
Ever lose a bolt while working on your car, and then have a hard time finding it? Imagine that while working on industrial piping. Well it happens. When a new pipe goes up, many items can find their way trapped in the pipe, and when the unit is first started up, those items go racing to the end of the pipes. Many times leading into a unit or a pump.
A simple bolt in a new pump is a recipe for disaster. The pump is blown. It has to be removed and repaired. They are often in hard to access locations, covered with guards and shrouds. Crews come in! Permits! Downtime! Behind schedule!
But this simple item could have prevented that. The Witch Hat Strainer (also called a Start-Up Strainer), is placed in-line to catch items like bolts, nuts, tools, debris and anything that may have found it’s way in the line during installation or maintenance.
The Gator is a remote controlled tank cleaning unit we built for Veolia Environmental Services. It is driven into large tanks to clean the walls of hazardous materials. Its infrared lights cut through the dark and mist while recording all operations from the safety of a control booth.
This is a test of the unit running up a ramp and squeezing through a manway as it would enter a tank in the field.
