What must non-standard boilers have stamped on them?

Non-standard boilers must have "Texas Special" stamped on them to indicate that they do not conform to the standard specifications set by the relevant authorities but have received special approval. This designation is crucial for ensuring that these boilers are recognized and authorized for operation within Texas, even though they may not meet the universal standards applied to standard boilers.

The "Texas Special" stamp signifies that the boiler has undergone a thorough review and inspection process specific to its design and construction, allowing it to operate safely and legally within the state. This ensures that operators and stakeholders are aware of the boiler's unique status and regulatory compliance.

Understanding this designation is vital for those involved in boiler operations, as it highlights the need to follow specific guidelines and requirements that apply to non-standard equipment.
