Ensure the sealing surfaces are clean, dry, and free of grease.

确保密封面干净、干燥、无油脂。

Position the gasket so that it is centered on the flange.

将垫片放在法兰的正中心(借助于螺栓位置)。

Lubricate the fasteners well. Be sure to lubricate all load bearing surfaces on the bolts, nuts, and washers.

充分润滑紧固件。 确保螺栓、螺母和垫圈上的所有承载表面得到充分润滑。

Assemble bolts, washers and nuts on the flange.

将螺栓、垫圈和螺母装配到法兰上。

Finger-tighten the bolts, moving in a circular direction.

用手指拧紧螺栓,按圆周方向转动。

Utilize a calibrated torque device to torque each bolt in a star pattern sequence.

使用校准后的扭矩设备,按照星形顺序扭转每个螺栓。 按三步式应用扭矩:

  • 第一步: 目标扭矩的30%
  • 第二步: 目标扭矩的60%
  • 第三步: 目标扭矩的100%
Apply the torque at 100% of Target Torque in a circular pass.

按照目标扭矩的100%,以圆周方向应用扭矩。 然后等待四个小时。

Complete the installation by performing circular passes until all bolts have acheived the target torque.

以圆周方向应用扭矩,直至所有螺栓均已达到目标扭矩,完成安装。
