Stub End Lap Joint
V M ALLOYS is a prominent manufacturer of stainless steel cross, carbon steel cross and alloy steel cross fittings, commonly known as a 4-way pipe fitting. Cross tee usuAlloy generates high stress on as temperature changes, because they are at the center of four connection points. In comparison, a tee is steadier than a cross, as a tee behaves like a three-legged stool, while a cross behaves like a four-legged stool.
Various grades of pipe caps manufactured by V M ALLOYS includes 304/304L, 316/316L, 321, 347, 317L, 310S, 904L, Duplex, Alloy 201, Alloy 800H, Alloy C276, Cupro Nickel, Alloy 400, Alloy 625 and Alloy 600. Our stocking program includes stainless steel pipe caps and carbon steel pipe caps of standard sizes and grades. Our specialty is to offer our customers with pipe caps in various shapes – round, square, rectangular or other special shapes.
