SUBSTRATE TUBE FOR SEPARATION MEMBRANE, SEPARATION MEMBRANE ELEMENT, METHOD FOR MANUFACTURING SUBSTRATE TUBE FOR SEPARATION MEMBRANE, AND METHOD FOR PRODUCING SEPARATION MEMBRANE ELEMENT
To provide a substrate pipe for separation membrane and a separation membrane element which can suppress defects of a separation membrane, and can suppress reduction in area such that a separation membrane can be formed, and a method for producing them.SOLUTION: A substrate tube for separation membrane includes a porous tube, a fitting member fixed to the porous tube, and a seal layer of which at least a part exists between the porous tube and the fitting member. The seal layer is continuously provided on an inner peripheral surface, an end face and an outer peripheral surface in the porous tube. The fitting member includes a fitting part which is inserted into the porous tube from the side of the end face and comes in contact with the seal layer. In the seal layer, a length Lin an axial direction of the porous tube in a portion provided on the outer peripheral surface is 1 time or more and 3 times or less a length Lin the axial direction in a portion inserted into the porous tube in the fitting part.SELECTED DRAWING: Figure 1
【課題】分離膜の欠陥を抑制でき、分離膜を形成できる面積の減少を抑制できる分離膜用基体管、分離膜エレメント、及びそれらの製造方法を提供すること。【解決手段】分離膜用基体管は、多孔質チューブと、前記多孔質チューブに固定された嵌合部材と、少なくとも一部が前記多孔質チューブと前記嵌合部材との間に存在するシール層とを備える。前記シール層は、前記多孔質チューブにおける内周面、端面、及び外周面に連続して設けられる。前記嵌合部材は、前記端面の側から前記多孔質チューブ内に挿入され、前記シール層と接する嵌合部を備える。前記シール層のうち、前記外周面に設けられた部分の前記多孔質チューブの軸方向における長さＬ１は、前記嵌合部のうち、前記多孔質チューブ内に挿入された部分の前記軸方向における長さＬ２の１倍以上３倍以下である。【選択図】図１
