Elbow

Elbow is a pipe fitting that turns the pipe. EL Elbow

1. Reducing elbow Elbow with different diameters at both ends

REL Reducing elbow

2. Long radius elbow Elbow with a bending radius equal to 1.5 times the nominal size of the pipe

ELL (LR) (EL) Long radius elbow

3. Short radius elbow Elbow with a bending radius equal to the nominal size of the pipe

ELS (SR) (ES) Short radius elbow

4. 45° elbow Elbow that turns the pipe 45°

5. 90° elbow Elbow that turns the pipe 90°

6. 180° elbow (return elbow) Elbow that turns the pipe 180°

7. Seamless elbow Elbow made of seamless steel pipe

8. Welded elbow (seam elbow) Elbow formed and welded with steel plate

9. Miter elbow (shrimp waist elbow) Elbow shaped like a shrimp waist welded from trapezoidal pipe sections

MEL Mitre elbow

Bend

Tee

A T-shaped or Y-shaped pipe fitting that can connect three pipes in different directions.

Equal diameter tees are tees with the same diameter.

Reducing diameter tees are tees with different diameters.

T Tee

LT Lateral tee

RT Reducing tee

45YS 45° Y-type tee

45YR 45° Y-type tee

Cross

A cross-shaped pipe fitting that can connect four pipes in different directions. cross

Cross with the same diameter. CRS straight cross

Reducing cross with different diameters.CRR reducing cross

Reducing cross (one branch port is a reducing cross) reducing cross (reducing on one outlet)

Reducing cross (one straight port and branch port are reducing cross) reducing cross (reducing on one run and outlet)

Reducing cross (two branch ports are reducing cross) reducing cross (reducing on both outlet)

Reducing cross (one straight port and two branch ports are reducing cross) reducing cross (reducing on one run and both outlet)

Reducing pipe (reducing head)

Straight-through pipe fittings with different diameters at both ends.

Concentric reducer (concentric reducer) Reducer with overlapping center lines

Eccentric reducer (eccentric reducer) Reducer with non-overlapping center lines and one side is straight.

R Reducer

CR Concentric reducer

ER Eccentric reducer

Pipe clamp

A pipe fitting with internal threads or sockets used to connect two pipe sections

Double-threaded pipe clamp A pipe clamp with threads on both ends.

Single-threaded pipe clamp A pipe clamp with threads on one end.

Double-socket pipe clamp A pipe clamp with sockets on both ends.

Single-socket pipe clamp A pipe clamp with a socket on one end.

Reducing double-socket pipe clamp A pipe clamp with sockets on both ends and different diameters.

Reducing threaded pipe clamp A pipe clamp with internal threads on both ends and different diameters.

CPL Coupling

FCPL Full coupling

HCPL Half coupling

RCPL Reducing coupling

Full thread coupling

Half Cplg half thread coupling

Internal and external thread coupling (internal and external thread)

A pipe coupling used to connect pipes of different diameters, with internal threads on one end and external threads on the other end.

BU Bushing

HHB Hexagonal head

FB Butt joint

Union Hose coupling

Union consists of several components, which are used to connect pipe sections and facilitate the installation and removal of pipe couplings of other pipe fittings and valves on the pipeline.

Hose coupling can quickly connect the pipe coupling of the hose.

UN Union

HC Hose coupler

Straight-through pipe fittings with external threads.

Single thread nipple A nipple with external threads on one end.

Double thread nipple A nipple with external threads on both ends.

Reducing nipple A nipple with different diameters at both ends

SE Stub end

NIP Pipe nipple or straight nipple

SNIP Swaged nipple

NPT = National pipe thread = American standard thread

BBE Bevel both ends Bevel at both ends

BSE Bevel small end Bevel at small end

PBE Plain both ends Plain end

PLE Plain large end Plain end at large end

PSE Plain small end Plain end at small end

POE Plain one end Plain end at one end

TOE Thread one end — end thread

TBE Thread both ends Thread at both ends

TLE Thread large end Thread at large end

TSE Thread small end Thread at small end
