Butt-welded pipe caps, due to their welded connection method, are typically used in applications requiring high strength and good sealing, such as petrochemicals, nuclear power, machinery, medical equipment, fertilizers, shipbuilding, waterproofing, and pipelines. They are also widely used in piping systems in the water, beverage, beer, and food industries.
Butt-welded pipe caps conform to Chinese national standards GB/T12459, GB/T13401, HG/T21635/21631, SH3408/3409; American standards ANSI/ASME B16.9/MSS SP 43; Japanese standards JIS B2311/2312/2313; German standards DIN2605/2615/2616/2617; and European standard EN10253. The production standard ASME B16.9 is one of the internationally recognized standards for manufacturing stainless steel pipe fittings, specifying requirements for the dimensions, materials, pressure ratings, markings, and inspection of butt-welded pipe fittings.
