Company news

As we all know, plastic hoses include steel wire pipe, wire pipe, hose, snake skin pipe, fiber pipe, high-pressure pipe, composite pipe, rubber and plastic pipe, plastic rib pipe, etc. Today we mainly talk about PVC steel pipe.

PVC钢丝管在行业内的名字有很多，pvc钢丝增强软管，弹簧管，钢丝缠绕透明管、钢丝软管、钢丝管等，

PVC steel wire pipe has many names in the industry, such as PVC steel wire reinforced hose, spring pipe, steel wire wound transparent pipe, steel wire hose, steel wire pipe, etc,

透明钢丝管也就是PVC钢丝螺旋增强软管，在PVC软管行业内部简称为“钢丝管”。该产品以PVC塑料为主体进行制作，内嵌螺旋钢丝作为增强层，故而该产品刚柔兼备，既具有足够的力学性能和刚性的同时，兼备优异的柔韧性。一般根据软管的性能，各大厂家会将其分为普通pvc钢丝螺旋增强软管，pvc钢丝高强度涤纶纤维复合增强软管，食品级pvc钢丝螺旋增强软管，pvc耐高温/耐低温钢丝螺旋增强软管，pvc防静电钢丝螺旋增强软管等等。

Transparent steel wire pipe, namely PVC steel wire spiral reinforced hose, is referred to as "steel wire pipe" in the PVC hose industry. The product is made of PVC plastic as the main body and embedded with spiral steel wire as the reinforcing layer. Therefore, the product has both rigidity and flexibility. It not only has sufficient mechanical properties and rigidity, but also has excellent flexibility. Generally, according to the performance of the hose, major manufacturers will divide it into ordinary PVC steel wire spiral reinforced hose, PVC steel wire high-strength polyester fiber composite reinforced hose, food grade PVC steel wire spiral reinforced hose, PVC high temperature / low temperature resistant steel wire spiral reinforced hose, PVC anti-static steel wire spiral reinforced hose, etc.

主要用途：

Main purpose:

PVC钢丝软管根据用途可以分为工业级（专门输送工业用水，输油，污水，粉料、化工原料等）和食品级（食品厂输送果汁，奶汁，食用水，酒厂输送白酒、啤酒，等），风力发电、吸排水、油、低浓度化学品等液体及固体颗粒、粉状物料。无论用途是什么，物质本身必须为“无腐蚀性”“低浓度化学品”物质。

PVC steel wire hose can be divided into industrial grade (special industrial water, oil, sewage, powder, chemical raw material, etc.) and food grade (food factory conveying juice, milk, edible water, Baijiu liquor, beer, etc.) according to its usage, such as liquid and solid particles and powdery materials such as wind power, water absorption, drainage, oil, low concentration chemicals, etc. No matter what the purpose is, the substance itself must be "non corrosive" and "low concentration chemical" substances.

PVC钢丝管为内嵌钢丝骨架的PVC软管。内外管壁透明、光滑、无气泡，流体输送清晰可见；耐低浓度酸碱，高弹性、不易老化，使用寿命长；抗高压， 在高压真空下能保持原状。

PVC steel wire pipe is a PVC hose embedded with steel wire skeleton. The inner and outer pipe walls are transparent, smooth and free of bubbles, and the fluid transmission is clearly visible; Resistance to low concentration of acid and alkali, high elasticity, not easy to aging and long service life; Resistant to high pressure and can remain unchanged under high pressure vacuum.

鉴别优劣

Identify advantages and disadvantages

为满足各行业领域的作业需要，钢丝管的需求量逐日递增。诞生了很多钢丝管的生产厂家，所生产的pvc透明钢丝管是五花八门，质量上也是千差万别，那应该如何选择质量好的钢丝管，怎么判断质量的好坏呢？

In order to meet the operation needs of various industries, the demand for steel pipe is increasing day by day. Many steel pipe manufacturers have been born. The PVC transparent steel pipe produced is diverse and the quality is also very different. How should we choose the steel pipe with good quality and how to judge the quality?

为了让顾客在选择上避免不必要的经济损失，下面总结了几项判断钢丝管的质量的方法？

In order to let customers avoid unnecessary economic losses in selection, the following summarizes several methods to judge the quality of steel pipe?

一、在条件允许的情况下，可用专业仪器进行测试PVC钢丝管的受热变形温度或维卡软化点，色度、浑浊度，耐正负压能力、爆破压力，卤素、硝酸盐含量，以及拉伸强度等来判断钢丝管的质量好坏。

1、 When conditions permit, professional instruments can be used to test the heating deformation temperature or Vicat softening point, chromaticity, turbidity, positive and negative pressure resistance, bursting pressure, halogen and nitrate content, and tensile strength of PVC steel pipe to judge the quality of steel pipe.

二、在没有技术条件的情况下，可以利用视觉、嗅觉、触觉等方法来判别pvc透明钢丝管质量的好与坏。

2、 In the absence of technical conditions, visual, olfactory and tactile methods can be used to judge the quality of PVC transparent steel pipe.

a. 观察钢丝管的壁厚是否均匀，如果厂家允许可从中间取样这样更为直接，主要是为了防止不法分子在生产过程中弄虚作假，管壁的厚薄不均匀会导致在使用过程易断裂、易爆破，严重缩短钢丝管的使用寿命。

a. Observe whether the wall thickness of the steel pipe is uniform. If the manufacturer allows, it can take samples from the middle, which is more direct, mainly to prevent criminals from practicing fraud in the production process. The uneven thickness of the pipe wall will lead to easy fracture and blasting in the use process, and seriously shorten the service life of the steel pipe.

b. 质量好的钢丝管应该透明、无味，通过特殊工艺加工的颗粒，晶莹剔透，没有任何杂质；反之，低质量的pvc软管颗粒掺杂杂质，会出现泛黄、管壁模糊不透明、不抗老化等特性

b. The steel wire pipe with good quality shall be transparent and tasteless, and the particles processed by special technology shall be crystal clear without any impurities; Conversely, low quality PVC hose particles doped with impurities, will appear yellowing, tube wall fuzzy opaque, anti-aging and other characteristics.

c. 在照明条件良好的情况下观察管壁是否有气泡、糊料等。

c. Observe whether there are bubbles, paste, etc. on the pipe wall under good lighting conditions.

d. 高质量的钢丝管气味非常的小，除微弱的塑料味之外，无任何像石油添加剂之类的刺激性气味，反之，低质量的钢丝管气味刺鼻，利用大量回收料及化工原料添加而成，尤其是在温度高的季节，根本无法靠近，气味很大。

d. The smell of high-quality steel pipe is very small. Except for the weak plastic smell, there is no pungent smell such as petroleum additives. On the contrary, the smell of low-quality steel pipe is pungent and is added with a large number of recycled materials and chemical raw materials. Especially in the season with high temperature, it is impossible to get close at all and has a great smell.

e. 从钢丝管的断切面取一段钢丝来做实验，看看是否易折断，质量好的钢丝需要专业工具进行裁切，质量好的钢丝管除了保证其柔韧度之外，更需要增加它的抗拉伸强度。

e. Take a section of steel wire from the cutting surface of the steel wire pipe for experiment to see whether it is easy to break. High quality steel wire needs professional tools for cutting. High quality steel wire pipe needs to increase its tensile strength in addition to ensuring its flexibility and toughness.

f. 高质量钢丝管，内外壁光滑，钢丝缠绕均匀，反之低质量的钢丝管手感粗糙、透明度不高等等。

f. High quality steel pipe has smooth inner and outer walls and even steel wire winding. On the contrary, low quality steel pipe has rough hand feel and low transparency.
