Deskripsi standar perlengkapan hidrolik II

Japan's standard

In Japan, there are two types of pipeperlengkapan biasanya digunakan

(1) SemuaKomatsu units use fittings with a 30°taper seat and metric fine thread. All flanges are type 61 or 62 (except -10*). (2) Most other Japanese equipment uses fittings with 30°taper seat and British standard straight thread, commonly known as JIS(Japanese industrial standard) fittings. These fittings are not interchangeable with inch fittings because their cones are in opposite directions. All flanges are type 61 or 62 (except -10*).

30 Jepang°taper Angle straight thread

Description: Japanese 30°taper Angle external thread joint can only be matched with Japanese 30°taper Angle internal thread. Both internal and external threads are straight threads with 30°taper seat. The seal is formed at the 30°cone seat. The threads on 30°taper Angle joints made in Japan conform to JIS B 0202 standard and are the same as BSPP threads. Both the British and Japanese perlengkapan have a 30°cone seat, but they are not interchangeable because the British cone seat is opposite to the Japanese cone seat.

30 Jepang°taper pipe threads

Description: Japanese taper pipeperlengkapan and BSPT(taper thread)perlengkapan are exactly the same, and completely interchangeable. The Japaneseperlengkapan does not have a 30°taper Angle, so it cannot be fitted with BSPP internal threads. This thread conforms to JIS B 0203 standard and is the same as BSPT thread. The seal of the Japanese taper pipe threadedperlengkapan is formed at the thread.

 Loose 30°taper straight thread

Description: Komatsu type 30°conical Angle straight thread joint and Japan 30°conical Angle straight threadperlengkapan except for the difference in thread, other aspects are completely the same. Small looseperlengkapan adopt metric fine thread, which conforms to JIS B 0207 standard. The looseperlengkapan is sealed at its 30°cone Angle.

Flensa longgarperlengkapan

Note: Loose flangehose fittings is similar to SAE 61 flange joint and is completely interchangeable. The o-ring sizes of various flanges are different. When replacing loose flanges with SAE-shaped flanges, always use SAE-shaped O-rings.
