世伟洛克提供多种尺寸、形状和材料的焊接接头，以满足不同的应用需求。这些选择包括高纯度和一般工业卡套管对焊接头、承插焊接头、焊接转换接头和水下焊接接头。微型世伟洛克 Micro-Fit® 接头具有与大型接头相同的流量和服务等级，设计紧凑，适用于狭小空间。
卡套管对焊接头的尺寸为 1/8 至 1 in. 和 6 至 18 mm，材质为 316、316L、316L VAR 和 316L VIM-VAR 不锈钢，旨在实现精确对准和均匀管壁，而公称管承插焊接头的管壁较厚，可在恶劣条件下延长使用寿命。选择焊接的接头、公称管和卡套管材料至关重要。使用相同的材料可确保相同的膨胀系数，并可减少焊接不良、不圆度或尺寸变化等不利于良好焊接的可能性。
