Product Description
Butt Welding CapCap is a part of the container, which is connected to the cylinder by welding. (as shown in the figure below) according to different geometric shapes, it can be divided into spherical, elliptical, dished, spherical crown, conical shell and flat cover, among which spherical, elliptical, dished and spherical crown type heads are also collectively referred to as convex heads. In welding, it is divided into butt welding head and socket welding head. It is used for various vessel equipment, such as storage tank, heat exchanger, tower, reactor, boiler, separation equipment, etc. The materials are carbon steel (A3, 20, Q235, Q345B, 16Mn, etc.), stainless steel (304, 321, 304L, 316, 316L, etc.), alloy steel (15Mo3 15CrMoV 35crmov 45crmo), aluminum, titanium, copper, nickel and nickel alloy, etc.If butt welding head products have splicing welds, there must be welding process card and corresponding welding process qualification. According to different head data, the welding methods adopted are mainly electrode arc welding, submerged arc active welding, gas maintenance welding, etc., with a wide range of plate thickness, which are all factors to be considered in the process of welding procedure qualification. Special post weld heat treatment shall be emphasized here. In the process of head depression, there are cold pressing and post weld heat treatment after hot pressing. In the same data, there may be several types of post weld heat treatment, and there are also cold pressed heads without heat treatment) which shall be distinguished and evaluated. In addition to the material group, welding method and thickness, the type of heat treatment shall be specially considered for the welding procedure qualification of the head manufacturer. The welding procedure qualification supervisor shall inspect and confirm one by one.Executive standardExecutive standard of head:Pressure vessel head GB / t25198-2010Pipeline standardGB / t12459-2005GB / t13401-2005Electric power standardDL/T695-1999D-GD87-0607Petrochemical standardSH3408-1996SH3409-1996Specification: dn15-dn1200;Wall thickness: sch5-sch160;Length: 89-343;Standard: ASME DIN JIS BS GB / T JB sh Hg;Application: petrochemical, nuclear power, machinery, medical equipment, chemical fertilizer, shipbuilding, waterproof treatment, pipeline, etc.Manufacturing standards: GB / t12459, GB / T13401, ASME b16.9, sh3408, sh3409, Hg / t21635,Installation of butt welding cap1. Measure the outer circumference of the cap. If the cylinder is processed in advance, please ask the manufacturer about the size of the outer circumference of the head.2. Please divide the outer circumference of the cap into 4 equal parts, and mark the cylinder and the head; 3. Weld the head and the cylinder, and the welding shall be selected by the customer according to the diameter and plate thickness;BUTT-WELDING PIPE FITTINGS DETAILS
