Custom Shrouds & Cores

Technology, Precision, And Value

For more than two decades, TPM sand screen and perforated tubing products have excelled in the most demanding applications worldwide.

Our production methods ensure consistent quality, while our service-oriented approach delivers the technical support and responsiveness for your most critical operations.

Custom Design Assistance

TPM works with you to develop new tubing products and refine existing designs. We can make short-length runs of prototypes for testing before we begin full-scale production.

If you have well-defined product specifications, we will use them to plan the most cost-effective, efficient way to manufacture your tubing. If you are unsure about the best design for your application, we provide all the assistance you need to specify and produce a finished product.

Proprietary Manufacturing Technology

Our production methods easily accommodate product features such as dimples, louvers, and tight restrictions that challenge other manufacturers. The versatility of our procedures and equipment enable us to adapt to your special requirements, optimize production speeds, and improve cost-effectiveness for you.

The TPM manufacturing process includes custom-designed mills incorporating spiral welding – a more demanding, but superior-quality technique.

Spiral Welding Advantages

The TPM spiral welding process is superior to conventional welding in the following ways:

  • Flexibility in handling a wide variety of designs/configurations
  • High strength
  • Greater rigidity at reduced wall thicknesses
  • Ability to produce large-OD tubes
  • Unlimited tube lengths
  • Production efficiency in short runs

TPM production capabilities accommodate a wide range of product designs and sizes. We have multiple modular production lines, each of which can be quickly re-tooled to handle large volumes or special requirements.


  • Diameters: .625 in. OD (15.875 mm) to
    15 in. OD (381 mm)
  • Wall Thicknesses: .025 in. (.635 mm) to
    .1875 in. (4.763 mm)
  • Lengths: Custom lengths, plus stock lengths from 2.5 in. (63.5 mm) to 38 feet (11.582 m)


  • Stainless steel and mild carbon steel
  • Titanium, nickel, HASTELLOY® and other exotic alloys

Perforation Patterns

  • Custom hole shapes, sizes, and patterns to suit any open-area requirement
  • Inventory of standard staggered and in-line patterns

Support Services

TPM can manage all aspects of production and coordinate any additional services you need:

  • Design
  • Component assembly
  • Inventory management
  • Shipping logistics
  • Packing and crating (including export crating)
  • Heat treating
  • Electropolishing
  • Coatings


TPM adheres to stringent quality assurance procedures, including 100% inspection of finished pieces. Every tubing joint receives a thorough examination of ID/OD, weld integrity, straightness, and length. TPM is able to validate the micron rating in our finished product.

TPM will also incorporate any additional quality requirements you may have. The TPM quality assurance program is fully documented and available for your review.

Material certifications are provided for every order, with complete listings of relevant chemical and physical properties. Every order is fully traceable back to the heat number of the raw material.
