Side and curved outside at least coat a circle.
Preferably, strengthening course is metal tape, and the both ends of metal tape weld together after tying up polyurethane insulation coating.
The utility model has the beneficial effects that：
1, curved outside is quarter turn details, and quarter turn details inner wall is equipped with thickening layer, can be improved to high pressure gas
The ability to bear of frictional force and impact force caused by stream mitigates the abrasion that turning is subject to, due to being provided with right-angled bend knot
Thickening layer at structure, even if thickening layer is nor affected on the sealing performance of elbow tube body, extend using the longevity by slight abrasion
Life；The deflector of side in swan neck body, can comb the air flow direction of high steam, and turning is avoided turbulent flow occur and wear and thicken
Layer, further improves the reliability and service life of elbow tube body.
2, deflector is the metallic plate that surface is coated with high-temperature-resantirust antirust paint, suitable for the environment of high-temperature steam, is used
Long lifespan.
3, the diversion trench in thickening layer can further function as the guide functions to high steam, and it is right to reduce high steam turbulent flow
The abrasion of thickening layer.
4, the strengthening course for coating curved interior and curved outside, can be improved the polyurethane insulation coating at quarter turn details
Tight ness rating and integral strength avoid polyurethane insulation coating from being occurred by the extruding of quarter turn details loose or damaged.
