Claims (1)
より内面ライニング管A、 Bを螺挿し、管A、 B
の端面4を、管端より挿着されるスリーブ付の防錆リン
グ3にて保護することを前提としたねじ継手において、
前記カップリング1内周の両端ねじ部2,2間に、内径
が当該ねじ部2の最小内径より小さく、最小で使用しよ
うとする防錆リング3のスリーブ部6の内径と同一の小
径部7を設け、前記ねじ部2から当該小径部7までの長
さが前記スリーブ部6の長さを越えないようにしたこと
を特徴とする内面ライニング管のねじ継手。The inner lining pipes A and B are screwed from both ends into the coupling 1, which has threaded parts 2 on the inner periphery of both ends.
In a threaded joint that is intended to protect the end face 4 of the pipe with a rust-proof ring 3 with a sleeve inserted from the pipe end,
Between the threaded portions 2 and 2 at both ends of the inner periphery of the coupling 1, there is a small diameter portion 7 whose inner diameter is smaller than the minimum inner diameter of the threaded portion 2 and which is at least the same as the inner diameter of the sleeve portion 6 of the rust prevention ring 3 to be used. A threaded joint for an internally lined pipe, characterized in that the length from the threaded portion 2 to the small diameter portion 7 does not exceed the length of the sleeve portion 6.
