Abstract
The utility model belongs to the metal pipe fittings field, and relates to a high pressure thick wall seamless hot pressing tee joint made by a seamless steel pipe, which includes a tee joint branch pipe (1) and a tee joint main pipe (2), wherein the tee joint external diameters D1 and D2 are 219.1-1219mm, the wall thickness S is 30-200mm, and the branch pipe height M and the main pipe length C can be set as required. The tee joint of the utility model made through advanced production and detection technologies has the advantages of high pressure resistance and high temperature resistance, symmetry overall structure and beautiful profile, high product quality, long service life, low production cost and high production efficiency. The high pressure thick wall seamless hot pressing tee joint takes the high-quality seamless steel pipe at home and abroad as raw materials, and the product accords with the home and abroad standard and the industry standard requirement. The tee joint of the utility model is widely used in petroleum, chemical industry, metallurgy, electric power, boiler, gas transmission or the like, and especially widely used in four pipelines (main steam, hot segment, cold segment, high pressure water supply) of a power plant.
Description
Technical field
The utility model belongs to the metal pipe element field, relates to the hot-forming seamless hot-pressed three-way pipe fitting of high pressure heavy wall of a kind of seamless steel pipe.
Background technique
Along with growing and scientific and technical the advancing by leaps and bounds of pipeline conveying industries, pipeline connected the quality requirement of required pipe fitting is more and more higher, demand is increasing.The working pressure of usually generally acknowledging is high-pressure pipe member greater than 10.0MPa.In known technology, the production of mesolow pipe fitting is comparatively general, Highpressure Tee mainly is to realize by welding and forging, welding tee arranges circumferential weld supervisor with the arm joint, welding and non-destructive inspection be difficulty comparatively, and Forged Tee need to be realized greater than three-port structure size and solid forging stock machining, and cost of production is high, is difficult to the height requirement of satisfying the market.
Summary of the invention
In order to overcome an existing manufacturing efficiency difficult problem low, backward in technique, the utility model provides a kind of seamless steel pipe the hot-forming seamless hot-pressed three-way pipe fitting of high pressure heavy wall.This threeway high pressure resistant high temperature resistant, overall structure is well-balanced, beautiful shape, simultaneously manufacturing efficiency is high, cost of production is low, advanced technology, reliable in quality, long service life.
The technological scheme that the utility model adopts is: the seamless hot-pressed three-way pipe fitting of high pressure heavy wall, comprise tee branch (1), threeway supervisor (2), described threeway can be born the pressure of 10.0MPa, between 30～200mm, arm height M, supervisor's length C can be set as required at 219.1～1219mm, wall thickness S for diameter D1, D2.Described threeway forms by advanced and mature heat pressing process manufacturing, takes advanced detection means to ensure the quality of products.
Above-mentioned threeway by material trademark be 20, the seamless steel pipe such as 20G, A106B, A106C, WPB, WPC, St35.8, St45.8,15CrMoG, 12Cr1MoVG, 10CrMo910,10Cr9Mo1VNb, 15NiCuMoNb5, P11, P12, P91, P92, WB36 is that the raw material manufacturing forms.
Above-mentioned threeway meets country, industry, foreign standard GB/T 12459, DL/T 695, SH 3408, SY/T 0510, HG/T21635, ASME B16.9 etc. fully to the requirement of product, and be widely used in the industries such as oil, chemical industry, metallurgy, electric power, boiler, gas transmission, especially in power station four large pipelines (main vapour, hot arc, cold section, high-pressure feed water), use comparatively extensive.
