hfw square pipe exporter

HFW square pipe offers an array of optimized sizes from 10  10 in (130  130 mm) to 16  16 in (400  400 mm), with wall thickness ranging from 0.120 in (3.0 mm) up to 0.500 in (12.7 mm). This particular tubing is crafted with the highest-frequency electric resistance welding (HFW) method, using hot-rolled steel coils as its fundamental source material.

The Benefits of Using HFW Piping Over UOE Piping

1. Due to the HFW pipe’s manufacturing process, there is no need for a U-shaped steel plate, which results in increased streamlined use of the underlying resources and cuts material costs.

When compared to UOE pipe, HFW pipe possesses a shorter welding line, resulting in a minimized welding heat affected zone and preserved structural dependability of the material.

Controlling the welding process for a HFW pipe is made surprisingly simpler through the uniformity of the weld bead, allowing the work to progress at an accelerated rate, resulting in greater production efficiency.

Boasting a tight bonding line and full, flat weld beads, the HFW pipe is an excellent source of reliable welding. With a low chance of defects such as slag inclusion and incomplete penetration, you can trust in its high-quality connection.

With reliable dimensional precision, the HFW pipe provides a consistent wall thickness post-welding, resulting in a significantly diminished level of ovality.

After undergoing welding, the HFW pipe is made even smoother with the help of an online straightening machine. This grants it more linearity than that of the UOE pipe.

The HFW piping exemplifies high-quality craftsmanship with a mercurial smoothness, and its welded surface presents a delightfully small surface roughness.

The fantastic HFW pipe supplies evenness and consistency; its wall thickness is consistent from end to end, with minimal variance in wall thickness.
