Head is a pipe fitting used to close the ends of pipes or containers, typically welded to the end of pipes or containers to form a seal. The product is widely used in equipment such as pressure vessels, storage tanks, and pipeline systems to close equipment ends and form enclosed spaces. Heads come in multiple types including elliptical heads, dished heads, spherical heads, and flat heads, with appropriate types selected according to different process requirements and space constraints. Heads are manufactured using high-quality carbon steel, stainless steel or alloy steel materials with excellent pressure resistance and corrosion resistance. The head has a reasonable design with uniform stress distribution, capable of withstanding internal and external pressure loads. The product is strictly manufactured according to international and national standards such as GB150 and ASME to ensure product quality and safety performance.
