摘要： Provided are a thermal insulating block structure for a skid post, capable of suppressing relative rotation among constructed thermal insulating blocks, and a construction method therefor. The thermal insulating structure is constructed by combining and stacking three types of thermal insulating blocks around a skid post 11, wherein the three types of thermal insulating blocks consist of: a lowermost thermal insulating block 3 disposed at a lowermost tier; a middle thermal insulating block 4 stacked on the lowermost thermal insulating block in at least one or more tiers; and an uppermost thermal insulating block 5 disposed on an uppermost tier of the middle thermal insulating block 4. The lowermost thermal insulating block has a concave part in a circumferentially middle region of an upper surface thereof, and two convex parts in circumferentially opposite end regions of the upper surface. The middle thermal insulating block has a concave part in a circumferentially middle region of each of an upper surface and a lower surface thereof, and two convex parts in circumferentially opposite end regions of each of the upper and lower surfaces. The uppermost thermal insulating block has a concave part in a circumferentially middle region of a lower surface thereof, and two convex parts in circumferentially opposite end regions of the lower surface. Each of the lowermost thermal insulating block, the middle thermal insulating block, and the uppermost thermal insulating block is provided in a number of two or more, wherein two or more pairs of adjacent ones of the convex parts of the upper surfaces of the two or more lowermost thermal insulating blocks which are placed adjacently are fitted, respectively, to the two or more concave parts of the lower surfaces of lowermost tiers of the two or more middle thermal insulating blocks, and two or more pairs of adjacent ones of the convex parts of the upper surfaces of uppermost tires of the two or more middle thermal insulating blocks which are placed adjacently are fitted, respectively, to the two or more concave parts of the lower surfaces of the two or more uppermost thermal insulating blocks.

摘要： In the conventional art, it is difficult to stably adjust the strength of a heavy wall steel pipe to a target strength of 95 to 140 ksi (= TS: 655 to 965 MPa) by one Q-T operation. Specifically, a method for manufacturing a heavy wall steel pipe includes a cooling step in which a steel pipe, with a wall thickness of 1/2 inch or more, that has been heated to the gamma range (i.e., austenite region) is dipped in water while supporting and rotating the steel pipe about the axis of pipe, an axial stream which is a water flow in the direction of axis of pipe is applied to the inside surface of the steel pipe under rotation in the water, and an impinging stream which is a water flow impinging on the outer surface of the pipe is applied to the outer surface of the steel pipe under rotation in the water. The rotation is performed at a circumferential velocity of pipe of 4 m/s or more, the application of the axial stream and the impinging stream is started within 1.1 s after the entire steel pipe is dipped, and continued until the temperature of the steel pipe is decreased to 150°C or lower, the pipe flow velocity of the axial stream is set at 7 m/s or more, and the discharge flow velocity of the impinging stream is set at 9 m/s or more.
