Pump stations for transporting Class A B and Class B liquids are located beneath steel structure pipe galleries; what are the fire protection requirements for such steel structures as specified in the codes?

Choose the higher standard, not the lower one; follow Class A standards!

If possible, it is recommended not to place it under the conduit tunnel. Petroleum standard 5.3.2: Pumps for liquefied hydrocarbons and flammable liquids with an operating temperature equal to or above their auto-ignition point should not be located beneath pipe racks. ”

5.6.2 The following parts of the load-bearing steel structures mentioned in clause 5.6.1 of this standard shall be covered with a fire-resistant layer; the fire resistance rating of the steel components covered by such a layer shall not be less than 2 hours. 1. Steel framework of supporting equipment: 1) Beams and columns of single-layer frameworks ； 2) When the floor slabs of a multi-story structure are open steel grating floors, the beams and columns within 10 meters above the ground level ； 3) When the floor slab of a multi-story structure is a closed-type slab, the beams and columns in the area from the ground level up to the surface of that floor slab and within an additional 10 meters above it ； 4) All beams, columns, and load-bearing bracings of the frame equipped with an air cooler at the upper part. 2. Steel support frames for supporting equipment ； 3. The uninsulated portion on the outside of the steel skirt base and the inside of the skirt base with a diameter greater than 1.2 m ； 4. Steel pipe frame: 1) Beams and columns supporting the pipes on the bottom layer ； When the base is below 4.5 m, the beams and columns of the support pipes within 4.5 m above the ground surface ； 2) The pipe rack equipped with an air cooler at the upper part, including all its beams, columns, and load-bearing bracing members ； 3) Pipe racks equipped with liquefied hydrocarbon or flammable liquid pumps at the lower section, as well as beams and columns within 10 m above the ground level ； 5. The main supporting members of the heating furnace in the range of 50 mm from the base plate of the steel column to the lower surface of the furnace bottom plate shall be covered with a fire-resistant layer; the crossbeams in direct contact with the furnace bottom plate shall not be covered with a fire-resistant layer ； 6. From the ground to 0.2 m below the point where the leg intersects the sphere of the liquefied hydrocarbon tank.

Thank you! I remember having seen that the steel structures above the pump station and within a 5-meter range on both ends were required to have fire-resistant coatings, but I can’t recall which standard specified this
