Pipe fittings are the general names of parts and components that play the role of connection, control, direction change, diversion, sealing and support in the pipeline system. Steel fittings are pressure fittings. According to the different processing technology, it is divided into four categories, namely, butt welding pipe fittings (divided into weld and no weld), socket welding and threaded pipe fittings, flange pipe fittings.

According to the application:
1. pipe fittings for connecting pipes are: flanges, live joints, pipe hoops, clamps, clamps, throat hoops, etc.
2. changing the direction of the pipe: bends, bends.
3. pipe fittings changing pipe diameter: variable diameter (different diameter pipe), different diameter elbow, branch pipe table, reinforcing pipe.
4. pipe fittings with additional piping branches: three links, four links.
5. pipe fittings for pipe sealing: gasket, raw material belt, thread, flange blind plate, pipe plug, blind plate, head, welding plug.
6. pipe fittings for pipe fixing: clasp, hook, ring, bracket, bracket, pipe clamp, etc.

According to the connection :1, welded pipe fittings 2, threaded pipe fittings 3, clamping pipe fittings 4, clamping pipe fittings 5, socket pipe fittings 6, rubber ring connection pipe fittings
According to the material divided into 1, cast steel pipe fittings 2, forged steel pipe fittings 3, alloy pipe fittings 4, stainless steel pipe fittings.
Pipe fittings are widely used in municipal, petrochemical, west-to-east gas transmission, ships and nuclear power.

Storage
NPS(SPS) is not combustible but assists combustion materials due to release of oxygen.Provided it is stored under appropriate condition.It must be stored dry in closed containers and protected from direct sunlight,heat and humidity.Impurities such as dirt,rust or traces of metal and reductants may cause catalytic decomposition.The product as supplied or in solution needs to be handled with appropriate care.The eye,skin and clothes must be protected when working with NPS(SPS) as damp powder or aqueous solution has a bleaching and slightly corroding effect.
Application
Polymerization : Initiator for the emulsion or solution Polymerization of acrylic monomers,vinyl acetate,vinyl chloride etc.and for the emulsion co-polymerization of styrene,acrylonitrile,butadiene etc.
Metal treatment : Treatment of metal surfaces(e.g. in the manufacture of semiconductors;
cleaning and etching of printed circuits),activation of copper and aluminium surfaces.
Cosmetics : Essential component of bleaching formulations.
Paper : modification of starch,repulping of wet - strength paper.
Textile : Desizing agent and bleach activator - particularly for cold bleaching.(i.e.bleaching of Jeans).
Others :
- Chemical synthesis
- Water treatment(decontamination)
- Waste gas treatment,oxidative degradation of harmful substances(e.g.Hg)

BOARD BRACKET
...........................................

JRS Lock scaffold board bracket is used to create an extended work platform, wherever required. Made out of 48.3mm tubes, the board bracket helps to establish the scaffold structure. One end of the board bracket is secured to the main structure, while the other end remains suspended. "CODE:- EFC-3005"

LEDGER
...............................

The JRS Lock system Ledger fitted with forged ledger blades is used to connect the verticals or standards to each other, thus creating a platform. The Ledger blade fits between the two cups and is secured with a single hammer blow."CODE:- EFC-3002"

INTERMEDIATE TRANSOM
.......................................................

Intermediate Transom is used to make up for the distance between standards if it exceeds the span of scaffolds board. These are used to secure the 2 boards and 3 boards."CODE:- EFC-3003".

DIAGONAL BRACE
.....................................

A brace or diagonal gives rigidity to the structure. These are connected diagonally between verticals using the rotating ledger blades fixed at its ends."CODE:- EFC-3004".
