一、家庭煤气管材质：一般而言，我们所说的煤气管指的是家用的燃气管。在市面上，常见的燃气管材质有镀锌管，不锈钢波纹管，铝塑管，橡胶管等，它们的优缺点比较如下：
1、镀锌管镀锌管是指在钢管表面进行镀锌的一种管道，有热镀锌和电镀锌管之分，电镀锌管虽然制作成本低，但容易被腐蚀，因此，通常用于煤气输送的是热镀锌管。这种镀锌管不仅有较高的耐腐性，而且使用寿命还很长，不过由于其接口过多，施工麻烦，正逐步被市场所淘汰。
2、不锈钢波纹管不锈钢波纹管是一种柔软而且耐压的管件，除了用于煤气输送外，还运用于液体输送系统中，主要是为了补偿管道或其他机械设备连接端口的相互位移。不锈钢波纹管除了柔软耐压外，还具有质量轻、耐腐蚀、耐高温等特点，因此，我国目前燃气管基本向不锈钢波纹管方向发展。
3、铝塑管铝塑管的内外层都是一种特殊的聚乙烯材料，无毒环保而且质量轻盈，其“能屈能伸”的性质很是适合应用在家庭装修中。而铝塑管作为室内燃气管道的时候，能够经受强大的工作压力，而且由于管道可以延伸很长一段距离，需要接头的情况少，因此其对于气体的渗透率几乎接近于零。业主用铝塑管作为家庭煤气输送路线是安全可靠的，但要小心避免买到劣质的铝塑管，因为市场上劣质铝塑管受到碰撞时，很容易会出现弯曲、变形，甚至是破裂的情况，威胁业主们的生命财产安全。
4、橡胶管我国橡胶管行业发展已有50年的历史，其应用可谓非常广泛。与其他煤气管道一样，橡胶管同样具有耐腐、耐高温的特性，但其使用寿命比起其他类型管道却短得多，因而在我国，橡胶管已很少用于煤气输送中了。
二、家装时煤气管道的安装原则：煤气管道的安装关乎业主的生命财产安全，因此，国家及相关部门对此有一定的规范要求。煤气管道一般不能自行安装，先要报装，然后由煤气公司派人入户布管，最后由装修队伍按要求埋管。埋管时，业主一定要请专业的安装队伍，严格按照标准去安装煤气管道系统，并且还要注意以下几点：
1、管道不能安装在居室地下和卧室中，更不能经过配电间、进风道等地方，最好明装在厨房、走廊、楼梯间及辅助房间内。若有特殊情况必须穿越以上地方，管道的这段距离不能有任何接口。
2、煤气管道与其他诸如供暖、供热的管道以及输电线间的距离不得少于5cm，与配电箱、电器开关和接头间隔要大于30cm。
3、管道应敷设在非燃料的墙面上，若燃具靠近的墙面是易燃材料，必须做好防火措施。

注意事项如下：
1.煤气管道应沿非燃材料墙面敷设，当与其他管道相遇时，应符合下列要求：竖向平行敷设时，净距不宜小于100mm，并应位于其他管道的外侧；交叉敷设时，净距不宜小于50mm。
2.室内煤气管不宜穿越水斗下方。当必须穿越时，应加设套管，套管管径应比煤气管管径大二档，煤气管与套管均应无接口，管套两端应伸出水斗侧边20mm。
3.煤气管道安装完成后应作严密性试验，试验压力为300mm水柱，3分钟内压力不下降为合格。
4.燃具与电表、电器设备应错位设置，其水平净距不得小于500mm。当无法错位时，应有隔热防护措施。
5.燃具设置部位的墙面，为木质或其他易燃材料时，必须采取防火措施。
6.各类燃具的侧边应与墙、水斗、门框等相隔的距离及燃具与燃具间的距离均不得小于200mm。当两台燃具或一台燃具及水斗成直角布置时，其两侧进离墙之和不得小于1.2m。
