Abstract
The invention discloses a manufacturing method of a spiral wound flange. Strip steel is used as flange material. An inner wound plate, a flange bolt-hole tube, an outer wound plate and a bolt-hole tube pressure plate form a flange plate. The inner wound plate and the outer wound plate are provided with a planar tube opening end and a step-plane tube opening end respectively. A step-plane seal is limited by the outer wound plate. The manufacturing method has the advantages that manufacturing hours are reduced, energy consumption is lowered, material cost is reduced, ultrasonic testing is omitted, and large equipment for butt joint of large and deformed pipes is avoided; defects such as bubble or blister in the cover casting method are avoided by the clamping the flange plate; nonuniform forging and weld defect in forged flanges and flat plate butt-jointed welded flanges are also avoided, bilateral dislocation welding is performed to the outer wound plate, unilateral welding is performed to the inner wound plate, the bolt-hole tube pressure plate is fastened, and accordingly flaw detection is omitted and manufacturing cost is lowered; strength and rigidity of the flange plate are increased, and fastening performance is improved after butt jointing. The manufacturing method is applicable to container flanges and pipe flanges and belongs to the field of chemicals and metalwork.
Description
Technical field
The invention discloses wound form flange manufacture method, adopt the band steel as flange material, form flanged plate by interior winding plate, flange bolt hole pipe, outer winding plate, bolt hole pipe pressing plate, reduce manufacturing expense; Improve the flanged plate strength and stiffness, fastening performance is improved after the docking, belongs to the metal manufacture field.
Background technology
Present flange is casting, forging, welding, has no information dissemination and the research of adopting the bandcast material winding method to make flange.
Summary of the invention
Wound form flange manufacture method disclosed by the invention, inside and outside winding plate is divided into plane and two kinds of forms of cascaded surface at nose end, the sealing of cascaded surface form is spacing by outer winding plate, beneficial effect of the present invention is, reduce machining period, energy efficient and material cost are exempted the ultrasonic examination check, and docking large-scale, different in nature pipeline does not need main equipment; The clamping flanged plate does not exist bubble or the sand holes defective of covering casting method; Do not exist yet forge flange and dull and stereotyped butt welding acting flange forge inconsistent and weld defect, adopt outer winding plate bilateral dislocation welding, the one-sided welding of interior winding plate, the mode that bolt hole pipe pressing plate is fastening, exempt flaw detection, be applicable to vessel flange and pipe flange, belong to the metal manufacture field.

The specific embodiment
The internal diameter of technique circle coats the external diameter of docking pipeline or container port.
Twine the inner flange plate in end face alignment of technique circle, be wound into regulation after, pre-buried flange bolt hole pipe, adopt arc flange bolt hole pipe location girth sheets to cut apart the pre-buried flange bolt hole pipe in location, flange bolt hole pipe centring ring plate thickness equals the external diameter of pre-buried flange bolt hole pipe, twines the outward flange plate and makes flanged plate
General method is adopted in the manufacturing of technique circle, is processed into technique circle internal diameter form, take-up strap in the welding of the technique circle outside.Interior take-up strap initiating terminal is processed as the inclined-plane.
Adopt general method, will be with section bar to rotate or rotation technique circle.
Interior winding plate moulding, the welding location.
The pre-buried flange bolt hole pipe of welding distributes.
Distribution flange bolt hole pipe location girth sheets, the flange bolt hole pipe location girth sheets of large-sized flange plate adopts the assembly unit welding.
Twine the outward flange plate.
Inside and outside take-up strap width is identical, is wound in plane abutted flange plate.
Inside and outside take-up strap width is different, is wound in notch cuttype abutted flange plate.
At pipe side welded flange bolt hole pipe location girth sheets.
Adopt general metal solder mode, the winding flange after the welding carries out surface treatment, for example: sandblast, preservative treatment.
