性能特点：
performance features:

1.产品结构：加强筋螺旋焊接不锈钢管是一种新型的耐腐蚀性强的管材，管材基体采用304不锈钢，通过生产设备的特殊压辊组合将一定宽度的不锈钢板带进行折边、轧制成型后焊接成管；

1. product structure: the reinforced spiral welded stainless steel pipe is a new type of strong corrosion-resistant pipe. the pipe base is made of 304 stainless steel. the stainless steel strip with a certain width is folded and rolled by special pressure roller combination of production equipment and then welded to the pipe.

2.重量轻：相对于同等规格型号的其他管材，此种管材大大减少了管材重量，使得劳动强度低，施工效率较快；

2. light weight: compared with other pipes with the same specification and model, this kind of pipes greatly reduces the weight of the pipe, which makes the labor intensity low and the construction efficiency relatively fast;

3.环刚度高：采用304不锈钢带进行生产，管材不会出现变形或压屈失稳的现象，满足瓦斯抽放用管材负压性能要求；

3. high ring stiffness: produced by 304 stainless steel strip, the pipe will not be deformed or lose stability arising from deformation, which meets the requirements for negative pressure performance of methane gas drainage pipes;

4.耐腐蚀：加强筋螺旋焊接不锈钢管采用的304不锈钢带是奥氏体型不锈钢，此种类型的不锈钢是不锈钢材料中最优越的，因此不需要采用其他的防腐措施，即可具有优越的防腐性能；

4. corrosion resistance: the 304 stainless steel strip used for the reinforced spiral welded stainless steel pipes is austenitic stainless steel. this type of stainless steel is the most superior in stainless steels. thus, the corrosion resistance performance is still superior without any other corrosion resistance measure;

5.连接方式互换性：市场常用钢管一般采用法兰连接，加强筋螺旋焊接不锈钢管也可实现卡箍连接，在法兰与快速接头之间能实现互换，相应的提高了施工效率；

5. interchangeability of connection methods: the commonly used steel pipes in the market are generally connected by flange connection. the reinforced spiral welded stainless steel pipes also can be connected by clamp connection, achieving the interchangeability between the flange and the quick coupling and thus correspondingly improving the construction efficiency;

6.焊缝强度高：采用优质304不锈钢及经过特殊处理的焊丝进行管体焊接，焊缝强度高于普通焊接强度。

6. high weld strength: the pipe weld is carried out by high-quality 304 stainless steel and specially treated wire, thus the weld strength is higher than the ordinary weld strength.
