New & Replacement Chillers, Boilers and Cooling Towers – Mullin Mechanical & Welding is very skilled in the 

installation of Industrial and HVAC Piping Systems and equipment with the ability to implement the most complex Chilled Water, Condenser Water and Hydronic Systems.  Projects with tight scheduling and strategic planning set us apart from other mechanical contractors.  We are available for small retrofit projects or turn key central plant installations large or small.



Welded, Grooved, Aquatherm, ProPress and Fusion Systems – Our field installation technicians are able to install any type of mechanical piping system required for the project and have worked with all types of materials and systems.  We continue to trail all our employees on the installation processes for each system to assure high quality and customer satisfaction.



Water, Steam, Sanitary, Ammonia, Chemical, Gas, Fluid, Air and Slurry Systems – Mullins Mechanical & Welding has installed or serviced about any mechanical system you can name either industrial or HVAC.  

Understanding the design of the system, the installation process and finding solutions to problems are our primary objectives once we are engaged on a project.  You can trust Mullins Mechanical & Welding to deliver a product that looks and works as is designed.   



Underground Pre-Insulated and Standard Underground Piping Systems – Many contractors provide underground services.  Few contractors provide quality underground services provided per the design criteria and in accordance with OSHA guidelines and safe jobsite practices.  We understand underground piping systems of all varieties with multiple services such as water, steam and chemical transfer.



In House and On Site Pre-Fabrication – With our 25,000 square foot fabrication facility 

Mullins Mechanical & Welding will take on the toughest of projects and schedules.  In-house fabrication 

means time saved on critical time sensitive projects where there is no room for error.  Our fabrication equipment and personnel are ready to go at a moment’s notice when the need arises.  Our High-Bay area allows for precise fabrication of piping or equipment to be assembled in our shop and shipped to the site with as much of the system attached and complete.  When our team goes to work on any project you can bet we want to be as far ahead of the curve as possible so we will be looking for ways to save time with as much 

onsite pre-fabrication as possible as well.  Whether it be in our shop or on the jobsite, we will be looking for ways to assist our customer’s schedule and cut their cost by pre-fabrication. 


We are available to provide stand-alone piping fabrication for our customers in need of 

quick turnaround of pre-fabricated piping.  Our ability to provide precision drawings from 

your model or from owner provided isometric drawings is sure to give our customers the 

value they are looking for.
