The invention discloses a tubular product die head capable of eliminating a joint line. The tubular product die head is composed of a feeding hole, a tail die sleeve, a spure sperader, dynamic flow distributing ribs, a flow distributing bracket outer ring, a flow distributing bracket inner ring, an adjusting ring, a pressing plate, a mouth model, a mandril, a pressurizing ring and the like, wherein a dynamic wheel, a support rib, a bearing and a motor jointly constitute the dynamic flow distributing ribs; the dynamic flow distributing ribs are fixed on a flow distributing bracket; the motor drives the dynamic wheel to rotate; when melt flows through the dynamic flow distributing ribs, the melt is rapidly converged after flow distribution along with rotation of the dynamic wheel; and afterthe melt passes through the flow distributing bracket, the slightly bulged pressurizing ring applies certain pressure to just converged fluid, so that the converging effect is improved and the homogenization function is also expressed. Dynamic mechanical action and timely pressurization and convergence are provided at the flow distributing bracket, so that the joint line when a tubular product isextruded can be better eliminated to increase the compactness and greatly improve the mechanical property of the tubular product.
