    Butt Weld Fittings Type:
    -(SMLS or Welded) Elbow,45°,90°,LR,SR
    -(SMLS or Welded) Tee
    -(SMLS or Welded) Reducer
    -(SMLS or Welded) Stub Ends
    -Special Type acc. to customer's drawings.

    Elbow: according to different sizes, the elbow is divided into long radius elbow and short radius elbow; according to different manufacturing methods, it can be divided into push bending, squeeze bending and pipe bend bevelling.

    Tee: according to the size of the diameter, the tee is divided into equal diameter tee, reducing tee, y type tee.

    Reducer: reducer usually has concentric reducer and eccentric reducer.

    Cap: the cap is usually divided into flat cap and standard oval cap. Among them, the flat cover tube cap is easier to manufacture and lower in price, but its bearing capacity is not as good as that of the standard elliptical head, so it is often used under the condition of DN≤100 and medium pressure below 1.0mpa. The standard is an oval head with flanged edges. The ratio of the inner diameter of the ellipse to the length of the shaft is 2:1. It is the most widely used cap.
