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.

Quality

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.
