Steel Pipes Standardize Again—Pipeline Pros Rejoice Quietly
Published Date: 4/24/2026
Rule
Summary
Starting January 1, 2027, new updated pipe safety standards (ASTM A53/A53M) will kick in to keep pipelines safer and make rules clearer for everyone involved. This update affects pipeline companies and anyone who works with steel pipes, helping reduce confusion and save time without extra costs. If anyone has concerns, they can speak up by June 23, 2026, before the changes become official.
Analyzed Economic Effects
5 provisions identified: 5 benefits, 0 costs, 0 mixed.
Updated ASTM A53/A53M-24 Adopted
PHMSA will update the pipeline regulations to incorporate ASTM A53/A53M-24, approved March 1, 2024. The change becomes effective January 1, 2027 unless adverse comments are received by June 23, 2026; PHMSA also authorizes compliance after June 23, 2026.
Which Pipes and Specs Are Covered
The incorporated ASTM A53/A53M-24 standard covers seamless and welded black and hot-dipped galvanized steel pipe in sizes NPS 1/8 to NPS 26 and specifies chemical requirements such as carbon, manganese, phosphorus, sulfur, copper, nickel, chromium, molybdenum, and vanadium.
Reduced Compliance Burden for Operators
PHMSA says adopting the 2024 edition will reduce regulatory confusion and lower compliance burdens for pipeline operators, and it estimates total costs on the regulated community will be less than zero (i.e., net cost savings).
Maintains or Improves Pipeline Safety
PHMSA concludes the updated ASTM A53/A53M-24 will maintain or improve public safety and that updating the standard supports innovations in equipment, testing, and operations. PHMSA also states this update will help increase national pipeline transportation capacity and improve operators' ability to provide reliable, affordable natural gas.
Standard Is Available Free to Read Online
Under the Pipeline Safety, Regulatory Certainty, and Job Creation Act, the adopted standard is made available free of charge at ASTM's online reading room (link provided in the rule), and can also be obtained via the publisher contact information in Sec. 192.7 and 195.3.

2026-08144 — Administrative Rulemaking, Guidance, and Enforcement Procedures
The Department of Transportation is bringing back and improving the rules about how it makes new regulations, issues guidance, and enforces laws. This affects anyone involved in transportation safety and compliance, updating how decisions are reviewed and enforced. These changes kick in on May 27, 2026, aiming to make the process clearer and more efficient without adding new costs.
2026-09392 — Hazardous Materials: Notice of Applications for New Special Permits
The Department of Transportation is reviewing new special permit requests for safely moving hazardous materials, like damaged lithium-ion batteries. If you work with these materials, now’s your chance to comment before June 11, 2026. These permits could change how some dangerous goods are transported, making things safer and possibly saving money on special packaging rules.
2026-09304 — Pipeline Safety: Meeting of the Gas Pipeline Advisory Committee
The Gas Pipeline Advisory Committee is meeting on May 28, 2026, to talk about new safety rules for gas pipelines that affect pipeline companies and the public. They’ll review proposed changes aimed at making gas distribution safer, and everyone can join in person or online.

2026-08673 — Pipeline Safety: Adjustment to OPID Notifications for Construction; Correction
The Department of Transportation fixed a mistake in a recent rule about when gas pipeline companies must notify the government about construction costs. They’re raising the cost limits for reporting from $10 million to $20 million and from $200,000 to $300,000 to keep up with inflation. This change affects pipeline operators and helps make sure the rules match what was originally intended, starting May 5, 2026.
2026-08064 — Pipeline Safety: Removing Obsolete Provision From Safety-Related Condition Reporting Requirements for Hazardous Liquid and Carbon Dioxide Pipeline Facilities
Starting August 3, 2026, pipeline operators must stop sending safety reports by fax and switch to email only. This change affects companies handling hazardous liquid and carbon dioxide pipelines and speeds up how quickly safety info gets to the right people. No extra costs here—just a smoother, faster way to keep pipelines safe!
2026-08067 — Pipeline Safety: Removing Unnecessary Provision for Material Properties Verification During MAOP Reconfirmation
PHMSA is making pipeline safety rules simpler by removing a needless step that required testing certain pipe materials during pressure checks.
