Butt Welding 180 Degrees LR Return

SN Valve is a leading China butt welding 180 degrees lr return manufacturer. Butt welding 180 degrees lr return elbows are connected to the pipeline by welding and have a 180-degree bending angle and a long bending radius, hence the name long radius (LR) return elbow. The design of this elbow allows for smoother fluid flow through the pipeline, reducing flow resistance and pressure loss, while providing more space to accommodate piping layout and installation.

Figure-8 Blank

SN Valve is a leading China figure-8 blank manufacturer. The Figure-8 Blank is a specially shaped piping accessory that resembles the cross-section of the number ‘8’. It is mainly used in piping systems, especially in the need to isolate or cut off the pipeline medium occasions. Through the installation of 8-word blind plate, you can achieve effective isolation of the pipeline, so as to facilitate the overhaul, maintenance or replacement of other accessories in the pipeline.

Plate (PL) Flanges

Find a huge selection of Plate (PL) Flanges from China at SN Valve. Plate flat welding flange is a kind of flange cut from steel plate with a full flat flange face and a round bore in the center for connection with pipes or other flanges. The connection is usually made by flat welding, i.e., the flange is aligned with the protruding part of the pipe or equipment and then firmly connected by welding.

Soft Joint Flange

High quality soft joint flange is offered by China manufacturer SN Valve. Soft joint flange usually consists of a pair of flanges, a soft joint (e.g. made of rubber, plastic or other elastic materials) and a number of bolts and nuts. The soft joint sits between the two flanges and acts as a seal and cushion. This type of flange connection through the bolts and nuts to the two flanges closely clamped together, and use the elastic deformation of the soft joint to compensate for the piping system displacement, vibration and temperature changes and other factors caused by the stress.
