Product Description Dish head are used as a cap in order to end pressure vessels barrel. Depending to the design and construction of vessels, these caps are used in various configurations.MAITAN supplies the most common types as following: Hemispherical Elliptical (2:1) Torispherical Conical FlatProduction Methods1.Hot or cold forming with moulds With this method, discs or segments are pressed into their definitive size and shape using one or more press runs. Selecting cold pressing or hot pressing is depended to power of forming facilities. But a simple rule states that cold forming is mainly used when head diameter is small and thickness is limited and hot pressing is used to manufacture heads made by very thick plates.2.Cold pressing and flanging.This method is used for heads of large diameter with a moderate thickness. The disc is first pressed into a spherical cap and the spherical cap is then flanged by spinning machinery to obtain a defined knuckle radius with a straight flange. Naturally, these products can undergo heat treatment if required in order to meet certain specifications.3.Fabricated from spherical cap and segmentsThis method is used for larger sizes and/or thicknesses and with special materials and/or material combinations. The product is fabricated from hot or cold-formed segments. After pressing, all segments are calibrated and cut to size in accordance with the required form and dimension. The segments are then set up, test assembled and marked. The fabricated products can then be fully welded as required.Type of materials Technical requirements * according toDuplex Stainless SteelASTM/ASME SA182 F44, F45, F51, F53, F55, F60, F61Stainless SteelASTM/ASME SA182 F304,304L,F316,316L, F310, F317L, F321, F347 Carbon SteelASTM/ASME A105, A350 LF1, LF2, A266, A694, A765 Gr.2Alloy SteelASTM/ASME SA182 F1, F5, F9, F11, F12, F22, F51, A350-LF3Non FerrousTitanium, Brass, Al-Brass, Copper Nickel, Nickel Alloys, HastelloyTitanium ASTM/ASME SB381, Gr.1, Gr.2, Gr.5, Gr.7, Gr.12, Gr.16 Copper NickelASTM/ASME SB151, UNS 70600(Cu-Ni 90/10), 71500(Cu-Ni 70/30)Brass, Al-brassASTM/ASME SB152 UNS C10100, C10200,C10300,C10800,C12200Nickel AlloysASTM/ASME SB169,SB171, SB564, UNS 2200, UNS 4400, UNS 8825UNS 6600, UNS 6601, UNS 6625 Alloy 20ASTM/ASME SB472 UNS 8020HastelloyASTM/ASME SB564, UNS10276 ( C 276 )Claded materialsASTM/ASME SB898, SB263, SB264 or closerexplosion cladding, making materials of 2 in 1 or 3 in 1.Titanium- Steel, Nickel-Steel,Titanium- Copper, Stainless Steel- Carbon Steel, Alloys- Steel etc.
