Kumsoo Connecting Co., Ltd.

Advantages

• High quality metal weld.
• Capability to produce pipe having very close diameter thickness ratio.
• Capability to manufacture pipe as per API 5L Grade X-80 or Equivalent.
• Capability to manufacture Alloy Steel Pipes.
• Supply the items in a large variety of steel grades, specifications and dimensions.

Features

• High toughness, good uniformity and compactness.
• Welded internally and externally.
• It is more cost effective than their seamless equivalents.
• It is usually more readily available than seamless.
• Thanks to extremely high speed and deposition rate, the shorter lead time is required than seamless.
• The wall thickness of welded pipes is generally more consistent than that of seamless pipes.
• It allows more time for the price of the materials to fluctuate.
