国内最大的大口径钢管生产基地日前在广东省中山市建成。这座由华捷钢管厂投资７０００万元建成的大口径钢管基地，可年产３×１０４ ４４００～３０００ｍｍ的螺旋焊管。该厂还将引进一条１０万ｔ／ａ的大口径钢管生产线。螺旋焊管是我国９０年代新开发的品种，可用于煤气管
The largest large-caliber steel pipe production base in China was recently built in Zhongshan City, Guangdong Province. The large-diameter steel pipe base built by the Huajie Steel Pipe Plant with an investment of 70 million yuan can produce 3×104 4400-3000mm spiral welded pipes annually. The plant will also introduce a large-diameter steel pipe production line of 100,000 t/a. Spiral welded pipe is newly developed in China in the 1990s and can be used for gas pipes
