无缝异型钢管的型号包括哪些?怎么分类的?

发布时间:2019-03-27人气:129

无缝异型管是经冷拔制成各种异型的无缝钢管无缝异型管一般是根据断截面来区分的,按材料来说又可分为无缝钢管无缝异型钢管,铝合金无缝异型钢管,塑料无缝异型钢管无缝异型钢管的发展主要是产品品种的发展,包括断面形状、材质和性能。挤压法、斜模轧法和冷拔法是生产无缝异型钢管的有效方法,它适用于生产各种断面和材质的无缝异型钢管材。为了能生产品种繁多的无缝异型钢管,还必须拥有多种生产手段。20世纪90年代,我国在原来只有冷拔的基础上,又开发出辊拔、挤压、液压、旋轧、旋压、连轧、回转锻造和无模拔等几十种生产方法,并在不断地改进和创造新的设备与工艺。

Seamless special-shaped steel pipe is made of various special-shaped seamless steel pipe by cold drawing. Seamless special-shaped steel pipes are generally distinguished according to the broken section, and can be divided into seamless special-shaped steel pipes, aluminum alloy seamless special-shaped steel pipes, plastic seamless special-shaped steel pipes according to the material. The development of seamless special-shaped steel pipe is mainly the development of product varieties, including section shape, material and performance. Extrusion method, oblique die rolling method and cold drawing method are effective methods to produce seamless profiled steel pipes. They are suitable for producing seamless profiled steel pipes with various sections and materials. In order to produce a wide variety of seamless special-shaped steel tubes, it is necessary to have a variety of means of production. In the 1990s, on the basis of cold drawing, China developed dozens of production methods, such as roll drawing, extrusion, hydraulic pressure, spinning, spinning, continuous rolling, rotary forging and die-free drawing, and constantly improved and created new equipment and processes. 无缝异型钢管分,异型方管、矩无缝异型钢管、异型焊管、螺旋焊管,规格:20*20mm-500mm,壁厚0.6mm-20mm,螺旋钢管规格,219mm-2020mm,壁厚5mm-20mm.直缝规格有4分、6分、1寸、1.2寸、1.5寸、2寸、2.5寸、3寸、4寸、5寸、6寸、8 寸、102、108、127、133、139、159、168、177、194、219、273、325等规格无缝异型钢管一般多是指方矩型钢管。

Seamless special-shaped steel pipe is divided into four parts, special-shaped square pipe, moment seamless special-shaped steel pipe, special-shaped welded pipe, special-shaped welded pipe, special-welded pipe, spiral welded pipe, specification: 20*20mm-500mm, wall thickness 0.6mm-20mm, spiral steel pipe specification, 219mm-2020mm, 219mm-2020mm, wall thickness 5mm-20mm.Strait specification specification has 4 minutes, 6 minutes, 1 incincinch, 1.2 inch, 1.2 inch, 1 inch, 1.2 inch, 2 inch, 2.5 incincincincinch, 2.5 inch, 2.5 incinch, 2 incincincincinc3 incincincincincincinc, 4 incincincinch, 5 inch, 5 inch, The results of this study are as follows:1. 19, 273, 325 and other specifications of seamless special-shaped steel pipes generally refer to rectangular steel pipes.


无缝异型钢管分类

Classification of Seamless Special-shaped Steel Pipe

按钢管截面形状尺寸的不同又可分为等壁厚异型无缝钢管(代号为D)、不等壁厚异型无缝钢管(代号为BD)、变直径异型无缝钢管(代号为BJ)。

According to the shape and size of steel tube cross section, it can be divided into iso-wall thickness special-shaped seamless steel tube (code D), unequal-wall thickness special-shaped seamless steel tube (code BD), and variable-diameter special-shaped seamless steel tube (code BJ).

无缝异型钢管一般是根据断截面来区分的,按材料来说又可分为无缝钢管无缝异型钢管,铝合金无缝异型钢管,塑料无缝异型钢管。下面主要介绍一下钢管无缝异型钢管。

Seamless special-shaped steel pipes are generally distinguished according to the broken section, and can be divided into seamless special-shaped steel pipes, aluminum alloy seamless special-shaped steel pipes, plastic seamless special-shaped steel pipes according to the material. The following is mainly about the seamless special-shaped steel pipe.

钢管无缝异型钢管可分为椭圆形异型钢管、三角形异型钢管、六角形异型钢管、菱形异型钢管、八角形异型钢管、半圆形异型钢圆,不等边六角形异型钢管、五瓣梅花形异型钢管、双凸形异型钢管、双凹形异型钢管、瓜子形异型钢管、圆锥形异型钢管、波纹形异型钢管。

Seamless special-shaped steel pipe can be divided into elliptical, triangular, hexagonal, rhombic, octagonal, semi-circular, unequal hexagonal, five-petal plum-blossom, double convex, double concave, melon-shaped, conical and corrugated special-shaped steel pipes. Steel pipe.
