Abstract
The utility model discloses a forming die of a heat insulating coating of a deep water standpipe. The forming die is structurally characterized in that a die locking system, a die opening and closing device, die inclining equipment and a die inclining and locking device are arranged on a die supporting frame, wherein, pipe end plugging devices are mounted at two ends of the steel pipe; a material injecting opening is formed outside a heat insulating die; a material injecting pump is abutted with the material injecting opening; and the heat insulating die is controlled by an oil heating system. The forming die can satisfy the forming requirement of heat insulating coatings of steel pipes with diameters Phi larger than 425; and a main body of the heat insulating die is manufactured by adopting aluminum alloy materials, and the inner surface of the main body of the heat insulating die is polished, so that the adhesion between materials and the heat insulating die is reduced and the operation cost is lowered. Under the circumstance that the technological requirements are met, the forming die has the characteristics of low cost and high safety, and is convenient to operate.
Description
Technical field
The utility model relates to a kind of for the deep water standpipe is incubated a whole set of mould of designing and developing outward, can be used for the heat preservation construction of deep water standpipe.
Background technology
The main structure (i.e. " foam jacket tube ") that adopts the hard polyurethane foams insulation to add the outer protection of polyethylene of existing steel pipe insulation." foam jacket tube " moulding process mainly contains two kinds: " one-step method " and " two-step method "." one-step method " mainly is that the mechanization on the production line is produced caliber continuously at the insulating tube of φ below 425, and efficient is than higher; " two-step method " claimed " tube-in-tube method " again, and the caliber of production is bigger, mainly is mechanization to produce continuously, and efficient is lower.Used isocyanates produced by " one-step method " and " two-step method " insulating tube and two kinds of raw materials of compound polyethers are approximately about 55～70s from initial action to the time of accomplishing reaction and solidify, and the density of foam is generally 40～60kg/m
3, therefore can't bear bigger external pressure, only can be used for 300 meters dark in interior submarine pipeline.And the deep water insulating tube will bear very big seawater pressure.Present mature insulation construction mainly contains polyurethane elastomer insulating tube [being called for short GSPU (Glass Spheres Polyurethane) pipe] the two big classes of multi-layer polypropylene structure and filling glass microballon.The main GSPU pipe that adopts of deep water insulation, the GSPU pipe is a kind of elastomer that does not foam, the hollow glass microbead of main inner filling plays insulation effect.The compound polyethers that isocyanate material that the production of GSPU pipe is used and blending have hollow glass microbead is approximately about 5～10min (temperature is at 80 ℃) to accomplishing from initial action hardening time, and density is generally 500～700kg/m
3, do not have the polyethylene overcoat.So there is certain difference in the mould of deep water insulation mould and land insulating tube.
Summary of the invention
Be incubated different and the difference on the Processes and apparatus that causes of used material to conventional steel insulation and deep water standpipe, the purpose of the utility model is to provide a kind of deep water standpipe heat insulation coating mould.It is rational in infrastructure, easy to operate, production efficiency is high and security performance is high, can realize the complete set of equipments of deep water standpipe heat insulation coating moulding.
The utility model purpose adopts following technical scheme to realize:
A kind of deep water standpipe heat insulation coating mould mainly is made up of mould bracing frame, clamping system, mould open/close device, mould reclining device, mould inclination locking device, sprue, insulation mould, heating system for oil, pipe end shutoff.The mould bracing frame is provided with clamping system, mould open/close device, mould reclining device and mould inclination locking device; The steel pipe two ends is installed the pipe end plugging device; The insulation mould is provided with sprue outward, and the material feeding pump docks with sprue, heating system for oil control insulation mould.
The characteristics of the utility model:
1, the utility model has realized with isocyanates and blending the moulding of the compound polyethers of hollow glass microbead as the steel pipe heat insulation coating of insulation raw material being arranged, and has increased the mode of steel pipe insulation, has improved the efficient of deep water Crude Oil Transportation, has reduced cost.
2, the insulation dies cavity has adopted the baffling design, has selected the mode of heating of oil bath for use, has improved the efficiency of heating surface, has reduced energy waste.Mold integral tilts to have selected for use hydraulic tilt, the two kinds of devices of locking that tilt, and has improved the security performance of work.
3, insulation die main body aluminium alloy material, inner surface has reduced the bonding of material and mould through polishing, has reduced running cost.Satisfying under the condition of technological requirement, possessing low-cost, convenience operation.
