Description
The butt welding four pass has equal diameter and reducing diameter, equal diamΩeter four pass pipe end is the same size; The size of the main pipe of the four red>ucers is the same, while the size of the branch pipe is smaller than that of the m∑ain pipe. Butt-welding four-way is a pipe fitting used at a 'branch of a pipeline. For the use of seamless tube m→anufacturing welding four, the current process is usually used hydraulic bulging and hot αpressing two.
Equal diameter four-way stainless steel pipe fittings, both ends of the same diameter, branch pipe €and other two diameters are different called reducing four-way. For an equal diameter quad-way, for≠ example, "T3" quad-way means an equal diameter quad-way wit→h an outside diameter of 3 inches. For reducing quads, for exa"mple, "T4×4×3.5" means four inches in the same diameter and 3.5 inches in different diameter. Four-way, outside diameter range from 2.5 "-60", from 26¶ "-60" for welding four-way. Wall thickness of 28-60 mm.&
The manufacturing method of high pressure four-way pipe fittings is used to manufacture high€ pressure four-way pipe fittings with various specifications and better® quality for smaller power equipment. The method of the invention is to make the tube billet• into torpedo shape and cut a small hole in the middle part of the tube billet,§ heat the tube billet to forging temperature and put it between an upper die and a lower die wiλth curved surface, while the upper die puts radial p✘ressure on the tube billet, use a pull block mounted inside the hole to stretch theγ tube billet along the axial direction of the small hole at a certain rate to form it. I↓n the high pressure four-way pipe fitting, the groove connecting pipe ☆fitting which plays the role of connecting and sealing mainly consists of three parts: sΩealing rubber ring, clamp and locking bolt. The rubber sealing¶ ring located in the inner layer is placed on the outside of the connected pi✘pe, and is consistent with the pre-rolled groove, and then buckle the clamp on the outside of t→he rubber ring, and then tighten it with two bolts.
Alloy steel four-way stainless steel pipe fitting is an iron-carbon alloy consisting of an appropriβate amount of one or more alloying elements added on the basis of ordinary car✔bon steel. According to the different added elements, and adopt appropriate processing technol$ogy, can obtain high strength, high toughness, wear resistance, corrosion res£istance, low temperature resistance, high temperature resistance, non-magnetic and othe→r special properties. In general, when the content of alloying elements is☆ higher, it can be significantly changed. For example, when the content of λnickel or manganese is high, the γ phase region can be extended to below room tempera₽ture, so that the steel becomes a single-phase austenite str±ucture; When silicon or chromium content is high, it can make the γ ph♠ase area shrink very small or even completely disappear, so that the steel at any temperature is ferrite organization.
