Abstract
The utility model relates to a steel thick-wall seamless skew tee. The steel thick-wall welded skew tee of the original design is susceptible to the alternating stress and will crack due to fatigue. After being changed into the steel thick-wall seamless skew tee, the utility model can obviously improve the safe running capability of the tee.
Description
(1) technical field:
The design designs for model utility, belongs to the pipe fitting field.
(2) background technique:
This threeway is pipe fitting that confluxes in the conveyance fluid pipeline.This threeway all adopts thick walled steel tube weldering system to form at present, and because of often being in the working environment of high temperature, high pressure, weld seam is subject to the alternating stress effect and fatigue cracking.
(3) summary of the invention:
The utility model proposes the seamless skew T of a kind of steel thick wall in order to overcome above-mentioned defective, changes original steel thick wall weldering system skew T into steel thick wall seamless skew T.Can improve the safe operation ability of threeway so significantly.
(4) description of drawings:
Fig. 1 is a heavy wall skew T schematic representation main, that the arm solderless is seamed into type.
(5) embodiment:
As shown in Figure 1, the seamless skew T of this steel thick wall is that weld seam with master, arm place changes no weld seam design into.
Claims (1)
- The seamless skew T of steel thick wall is characterized by:1 steel;2 no weld seam skew Ts.
