The hydraulic pipe line-up clamp has strong power and is suitable for mountain and offshore operations.In 2017, in response to the construction requirements of the Maoming submarine pipeline project of Sinopec Shengli Oil Construction Company, our company developed a hydraulic pipe line-up clamp   and applied for a patent.It makes up for the inadequacy that the pneumatic pipe line up clamp can't adapt to the offshore construction operation, and the aligning misalignment is difficult to control.The construction period is greatly reduced, and the cost is greatly reduced.
