The invention discloses a spiral steel pipe with reinforcing rings and a manufacturing method of the spiral steel pipe. The steel pipe comprises a spiral pipe body formed by spirally winding main steel strips; spiral joints are formed between the adjacent main steel strips of the spiral pipe body; the reinforcing rings are spirally wound on and locked to the outer wall or the inner wall of the spiral pipe body; at the spiral joints, the reinforcing rings are formed by bending narrow steel strips and the sections of the reinforcing rings are circular-arc-shaped, square or trapezoidal. The reinforcing rings are capable of enhancing the overall annular strength of the pipe, the thickness of the pipe can be reduced by more than a half, and the cost can be greatly reduced; meanwhile, the inertia moment of the circumferential section of the pipe is increased exponentially; as a result, the effect of the reinforcing rings is much better than that of a common reinforcement way, and consequently, the deformation problem of a large-diameter steel pipe, in particular a steel pipe of which the diameter is greater than 4m, during production is solved, and a steel pipe with an ultra-large diameter (10m or above) can be produced. Besides, the spiral joints formed between the adjacent sections of the spiral steel pipe are capable of surrounding the reinforcing rings so that the leakage protection at the joints can be strengthened.

This invention relates to absorbent tampons. More particularly, the invention relates to an improved absorbent tampon having improved leakage performance. Tampons, having a primary absorbent member which is constructed from an absorbent material compressed to a self-sustaining form and a mass of secondary absorbent material are disclosed. The mass of secondary absorbent material is preferably located generally proximate the withdrawal end of the primary absorbent member, and is preferably substantially non-compress, and preferably of a smaller diameter than the primary absorbent member. The mass of secondary absorbent material may be a multiple pieces or one piece. The secondary absorbent material may be attached to the primary absorbent member, the withdrawal cord, or both, or may be integral with one or both of these members. The withdrawal cord of the tampon may have absorbent and non-absorbent zones, especially when the mass of secondary absorbent material is attached to the withdrawal cord. The mass of secondary absorbent material preferably has a lower total absorbency than the primary absorbent member. Preferably, the mass of secondary absorbent material is provided with a driving force to direct fluid toward the primary absorbent member. A preferred method of making a tampon of the present invention is also disclosed.

The invention discloses a steel tube tower column with reinforcing structures on the inner wall and a manufacturing method thereof. A plurality of ring-shaped reinforcing ribs or spiral reinforcing ribs are arranged on the inner wall of a tower column in the circumferential direction; reinforcing pillars are arranged on the inner wall, between the ring-shaped reinforcing ribs or the spiral reinforcing ribs, of the tower column; and crisscrossed reinforcing structures are formed between the reinforcing pillars and the ring-shaped reinforcing ribs or the spiral reinforcing ribs. The ring-shaped reinforcing ribs or the spiral reinforcing ribs on the inner wall of the tower column enhance the integral circumferential strength of a pipeline, increase the shearing resistance of the pipe wall, enable the thickness of a steel plate to be greatly reduced, ensure that steel pipes with super-large diameters can be manufactured, and can protect seams formed during the manufacture of the tower column; the reinforcing pillars can enhance the integral axial strength of the pipeline; wire ropes or steel strands are arranged in the reinforcing pillars filled with concrete, the concrete replaces a steel structure to bear the compressive stress, and the wire ropes or the steel strands bear a pulling force formed by wind load, so that the swinging amplitude of the tower top is reduced; and the manufacturing method is simple and feasible, the construction cost is lowered and the production efficiency is improved.

The present invention provides a pre-expanded tampon pledget formed from cellulosic absorbent fibers. The fibers are not tightly compressed, thus, the pledget has a reduced fiber density. As a result, a softer, more pliable pledget is formed that not only increases user comfort during use, but also affords a user with comparable and / or increased leakage protection over conventional tampons or tampon pledgets.

An absorbent article is disclosed that provides improved leakage protection. Also disclosed are methods for using and preparing absorbent articles having improved leakage protection, methods for designing articles having improved leakage protection, and methods of measuring and determining the performance index of an absorbent article. The absorbent article having improved leakage protection has a 3 variable urine only leakage performance index (PI3UL) of less than about 3.0, the PI3UL being determined in accordance with the following equation (1):PI3UL=0.046(Tc)−2.94(MS100)−0.772(AUL)  (1)where Tc is the total capacity in grams, MS100 is the percent utilization of the core upon insult with 100 ml of 0.9 wt % saline solution, and AUL is the front pad absorbency under load, expressed in grams of 0.9 wt % saline solution absorbed per gram of pad material.
