PE Valves

The MTD Inline POLYTAPP HDPE ball valve is offered in sizes ranging from 2- to 16-inch IPS and has a maximum operating pressure of 125psi. All sizes are SDR11, full-bore valves with either a short or extended stem that can be opened and closed with a quarter turn of the operator. The inline POLYTAPP is available in butt fusion x butt fusion, electrofusion x electrofusion or butt fusion x electrofusion.

Endcaps

MTD endcaps are offered in sizes ranging from 1-inch CTS to 8-inch IPS. Each endcap was designed to be as compact as possible to allow for easy installation in tight spaces.

Steel Control Fittings for Natural Gas Applications

MTD also offers a line of steel control fittings to meet our customers’ needs. These fittings are designed for our natural gas customers and provide the same level of quality and availability expected from MTD.

All MTD steel fittings are designed, tested and manufactured to be used on pipelines operating in accordance with ASME B31.8 or DOT 192. All welding and inspections are performed per API-1104 and ASME section IX. A material specification and other test reports is available for each fitting. All products go through our rigorous, ISO 9001 certified, quality management system.

Spherical Weld Tees ANSI 150

HiSeal Valves

Offering a several configurations and sizes, the HiSeal valve line offers industry-leading quality and safety. These valves are assembled using a patented assembly process that allows for consistent pressure to be applied to each side of the ball leading to consistently lower operation torque and lower defect rates. Additionally, integrated anti-static devices, fire safety devices and other safety and operation options are available.

Steel Fabrication for Natural Gas Systems

At MTD we pride ourselves on providing innovative and safe solutions to our customers. Our team members are ready to assist you in your custom steel fabrication design. The expertise from MTD in the natural gas industry is unparalleled.

For every fabricated project, CAD drawings are developed for your approval and a standardized drawing number is issued. From there, your custom design is realized in one of our state-of-the-art fabrication facilities. This includes abrasive blasting and advanced coatings for lasting protection and reliability. Additionally, test reports are available for all products along with an as-built drawing and a detailed traceability package.

Each welder in our facilities goes through rigorous internal testing and certification and is equipped with extensive knowledge of industry standards such as API 1104 and PHMSA 49 CFR 192. Our welders are also supported by at least one American Welding Society (AWS) Certified Welding Inspector (CWI) or Certified Associate Welding Inspector (CAWI) at each location. Through our ISO 9001:2015 certified quality management system, each project is inspected and/or tested at each stage of construction. Each test report is included in the quality package that is delivered with the finished good. Additionally, we store each quality and traceability package in our cloud based Doccenter for easy electronic retrieval.

Below are just a few types of projects we take on:

  • Regulator Stations
  • Meter Stations
  • Strainers
  • Custom Vaulting
  • Pig Launchers

PE Fabrication for Natural Gas Systems

Alongside manufacturing fittings and tools, we also offer custom polyethylene fabrication services. For example, if you have a standard configuration that is used in your system such as a tapping tee with a specific outlet length or type and integrated excess flow valve, we can make that happen. This service increases your operators’ efficiency as all that it reduces their workload to single fusion in the field. From to fabricating your standard service configurations custom PE valve stations, we are here to help.

With a team of experienced fusion operators that are requalified annually, all aspects of MTD PE Fabrication are tightly controlled. The whole process starts with your needs. From there, we will draft CAD drawings for your component but if you are not sure what you need, we are more than happy to design options for you. After you have decided on a drawing, we then make sure that all components used in its assembly are approved by your standards and engineering department so that there are no issues for your operators. We keep a record of your drawing forever. If there is ever a change needed, we create a new revision for you to approve. Once your drawing is approved and an order placed, that drawing is law. From tolerances to angles, each fabricated item is built to your specifications.

Through our ISO 9001:2015 certified quality management system, each run of PE fabrication is checked multiple times during the process, at the start of the run, throughout the run depending on volume, at the end of the run and after packaging.

Every fabricated item meets or exceeds the following standards:

  • ASTM F1055
  • ASTM F2897
  • ASTM D2513
  • ASTM D3350

All this to say that the limiting factor of MTD PE Fabrication is your imagination. All sizes, all fittings, all fusion types, integrated excess flow valves, cradles and more are at your disposal each assembled by a qualified fusion operator and built to your specification.
