1、无缝方管主要特性是无焊接缝,可接受较大的压力。产品能够是很粗糙的铸态或冷拨件。

1. The main characteristic of seamless square pipe is that it has no welding seam and can accept high pressure. Products can be very rough as-cast or cold-dial parts.

2、精细方管是近几年呈现的产品,主要是内孔、外壁尺寸有严厉的公差及粗糙度。

2. Fine square tube is a product presented in recent years, mainly with strict tolerance and roughness of inner hole and outer wall dimensions.
