Help needed regarding fireproof coatings in chemical manufacturing enterprises

It is required to be painted in accordance with the Petrochemical Specifications. 5.6 Fire protection for steel structures 5.6.1 Fire protection measures shall be applied to the following load-bearing steel structures. 1. Load-bearing steel frameworks, supports, and pedestals for Class A and B liquid handling equipment with a single volume of 5 m3 or more ； 2. The load-bearing steel frameworks, supports, and pedestals for materials and equipment that are highly toxic and pose an extreme risk in explosion-prone areas ； 3. Load-bearing steel frameworks, supports, and pedestals for equipment containing Class B or C liquids with a single volume of 5 m3 or more, at an operating temperature equal to or above their auto-ignition point ； 4. Steel support at the bottom of the heating furnace ； 5. Steel pipe framework of the main corridor within the explosion-hazardous area ； 6. Load-bearing steel frameworks, supports, and pedestals for non-flammable medium equipment within explosion-hazardous areas, with a height-to-diameter ratio of 8 or greater and a total weight of 25 tons or greater. 5.6.2 The following parts of the load-bearing steel structures mentioned in Article 5.6.1 shall be covered with a fire-resistant layer; the fire resistance rating of the steel components covered by this layer shall not be less than 1.5 hours: 1. Steel frames supporting equipment: 1) Beams and columns of single-layer frames ； 2) When the floor slabs of the multi-story structure are open steel grating floors, the beams and columns within a range of 10 m above the ground level ； 3) When the floor slabs of a multi-story structure are closed-type slabs, 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 ； 2. Steel support frames for supporting equipment ； 3. The uninsulated parts 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 ； Beams and columns of support pipes within 4.5m above the ground level ； 2) The pipe rack equipped with an air cooler at the upper part, including all its beams, columns, and load-bearing bracings ； 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 up to 0.2 m below the point where the leg intersects the sphere of the liquefied hydrocarbon tank.
