無縫異型鋼管的基本信息：包括橫斷面輪廓非圓形的、等壁厚的、變壁厚的、沿長度方向變直徑和變壁厚的、斷面對稱和不對稱的等。如方形、矩形、錐形、梯形、螺旋形等。無縫異型鋼管更能適應(yīng)使用條件的特殊性，節(jié)約金屬和提高零部件制造的勞動生產(chǎn)率。其廣泛應(yīng)用在航空、汽車、造船、礦山機械、農(nóng)業(yè)機械、建筑、輕紡以及鍋爐制造等方面。生產(chǎn)異型管的方法有冷拔、電焊、擠壓、熱軋等，其中冷拔法得到了比較廣泛的應(yīng)用。
The basic information of seamless special-shaped steel pipe includes non-circular cross-section outline, equal wall thickness, variable wall thickness, variable diameter and wall thickness along length direction, symmetrical and asymmetrical cross-section, etc. Such as square, rectangular, conical, trapezoidal, spiral and so on. Seamless special-shaped steel pipe can better adapt to the particularity of service conditions, save metal and improve labor productivity of parts manufacturing. It is widely used in aviation, automobile, shipbuilding, mining machinery, agricultural machinery, construction, textile and boiler manufacturing. Cold drawing, welding, extrusion and hot rolling are the main methods to produce special-shaped pipes, among which cold drawing is widely used.
下面來看看無縫異型鋼管的分類：異型管，異型方管、矩異型管、異型焊管、螺旋焊管，規(guī)格：20*20mm-500mm，壁厚0.6mm-20mm，螺旋鋼管.螺旋鋼管規(guī)格，219mm-2020mm，壁厚5mm-20mm.直縫規(guī)格有4分、6分、1寸、1.2寸、1.5寸、2寸、102、108、127、133、139、194、219、273、325等規(guī)格異型管一般多是指方矩型鋼管。
Let's look at the classification of seamless special-shaped steel pipes: special-shaped pipes, square pipes, rectangular special-shaped pipes, special-shaped welded pipes, spiral welded pipes, specifications: 20*20mm-500mm, wall thickness 0.6mm-20mm, spiral pipe specifications, 219mm-2020mm, wall thickness 5mm-20mm. Straight seam specifications have 4 points, 6 points, 1.2 inches, 1.5 inches, 2 inches, 102, 108, 127, 139, 194, 219, 273, 325 and other specifications. Typical pipe usually refers to rectangular steel pipe.
無縫異型鋼管廠擁生產(chǎn)機械分為兩種工藝，一種是采用金屬型材滾軋技術(shù)，另一種是采用異型模具冷拔技術(shù)。兩種工藝都是以圓管為原材料，將各種金屬類圓管(如焊管、不銹鋼管、無縫管、鍍鋅管、銅管、合金管等各種金屬管)滾軋成各種金屬類異型管(如橢圓管、平橢管，D型管、半圓管、六角管、蘑菇管、面包管、元寶管、T型管、H型管、三角管、方距管、方管等)所有金屬類異型管，操作簡便、產(chǎn)量高、無損耗、成本低、無表面明顯刮傷，更換模具時間短，可做多種材質(zhì)、形狀、厚度等優(yōu)點，從多方面滿足了社會生產(chǎn)需求。
The production machinery of seamless profiled steel pipe mill can be divided into two processes, one is the rolling technology of metal profiles, the other is the cold drawing technology of profiled dies. Both processes are based on circular pipe as raw material, rolling all kinds of metal circular pipe (such as welded pipe, stainless steel pipe, seamless pipe, galvanized pipe, copper pipe, alloy pipe, etc.) into all kinds of metal special-shaped pipe (such as ellipse pipe, ellipse pipe, D-shaped pipe, semi-circular pipe, hexagonal pipe, mushroom pipe, bread pipe, Yuanbao pipe, T-shaped pipe, H-shaped pipe, triangular pipe, square pipe, square pipe, etc.). It is a kind of special-shaped pipe. It has the advantages of simple operation, high output, no loss, low cost, no obvious scratch on the surface, short time to replace the mould, and can be made of various materials, shapes and thicknesses. It meets the needs of social production in many ways.
