Description
Technical Field
The utility model relates to a high wear-resisting high temperature resistant stainless steel seamless steel pipe.
Background
The stainless steel seamless steel pipe used in the high-temperature environment in the prior art is difficult to be subjected to wear-resistant treatment, and the main reason is that the wear-resistant layer is bonded on the outer surface of the steel pipe in the current mainstream wear-resistant means, and the high-temperature environment can cause accelerated aging or viscosity loss of the bonding layer between the wear-resistant layer and the outer wall of the steel pipe, so that the wear-resistant layer falls off, and the outer wall of the stainless steel seamless steel pipe is easy to be worn and corroded and has short service life.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provide a high-wear-resistance high-temperature-resistance stainless steel seamless steel tube.
The technical scheme of the utility model is that: the utility model provides a high wear-resisting high temperature resistant stainless steel seamless steel pipe, includes the steel pipe body, steel pipe body both ends are equipped with the joint, two the inboard steel pipe body outside of joint respectively is equipped with a spiro union portion, two steel pipe body outside between the spiro union portion is equipped with the location arch, protruding top face in location with the periphery of spiro union portion flushes mutually, still includes a ceramic pipe box, ceramic pipe box inner periphery have with the protruding corresponding slot in location, the steel pipe body peg graft in the ceramic pipe box, two locating flange spiro union respectively on the spiro union portion that corresponds right ceramic pipe box is fixed a position, still be equipped with the glass fiber layer between ceramic pipe box and the steel pipe body, still be equipped with the chrome-plated layer on the inner wall of steel pipe body, still be equipped with wear-resistant coating on the surface of ceramic pipe box.
Furthermore, a circle of fixing ring is arranged on the positioning flange, and the end part of the ceramic pipe sleeve is covered in the fixing ring.
Further, the glass fiber layer is a glass fiber felt, and the glass fiber layer covers the periphery of the steel pipe body.
Furthermore, the glass fiber layer is a glass fiber felt patch, and the glass fiber felt patch is applied to the top surface of each positioning protrusion through an adhesive.
The utility model has the advantages that: the utility model adopts the mode of sleeving the ceramic pipe sleeve outside the steel pipe to protect the outer wall of the stainless steel seamless steel pipe, the two ends of the ceramic pipe sleeve are fixed by the positioning flanges, the combination mode is firm and reliable, and the ceramic pipe sleeve plays a role in heat preservation, thereby preventing the fluid conveyed in the steel pipe from generating heat exchange with the external environment; the glass fiber layer is arranged between the ceramic pipe sleeve and the stainless steel seamless steel pipe, the glass fiber layer can play the roles of buffering and gasket, meanwhile, the heat preservation effect can be further enhanced, the corrosion resistance of the glass fiber layer is also strong, and the service life of the steel pipe can be effectively prolonged.
