Dear Mr. Broussard:
This is further to our acknowledgement of your letter of August 22, 1974, and Mr. Thomas L. Cairns' letter of November 8, 1974, addressed to Mr. Frank Fulton. In both letters, Brown and Root has requested an interpretation of Section 195.208.
Section 195.208 states, "Supports or braces may not be welded directly to pipe that will be operated at a pressure of more than 100 psig."
Attachments such as anchors, supports, braces, etc., may not be welded directly to carrier pipe. However, attachments may be welded or bolted to a separate cylindrical member which completely encircles the pipe with the encircling member welded to the pipe by continuous circumferential welds.
Section 195.208 is more restrictive than USAS B31.4-1974, 421(d), in that Section 195.208 requires compliance to this section at an operation pressure of more than 100 psig where B31.4 does not state a pressure.
Your proposed design for Union Carbide Corporation would be in compliance with Section 195.208 as long as your pipe shoes completely encircles the pipe with the encircling member welded to the pipe by continuous circumferential welds.
If we can be of any further assistance in this matter, please advise.
Sincerely,
/signed/
Joseph C. Caldwell
Director
Office of Pipeline Safety
