Definitions In Piping

Alloy Steel: Steel that has special attributes other than carbon steel. Steel can be considered as an alloy steel blend elements if mangan, silicon, and copper exceed the following: 

Manganese (Mn) = 1.65% 
Silicon (Si) = 0.60% 
Copper (Cu) = 0.60% 

Besides, also added another element in the mix to get a certain amount combine effect in accordance with the limits of alloy steel that has been approved. Elements, among others, blend the following: 

Aliminium (Al), Booron (Br), Chromium (Cr) to 3.99%, Cobalt (Co), Columbium (Cb), Molybdenum (Mo), Nickel (Ni), Titanium (Ti), Tungsten (TS), Vanadium ( Va), Zirconium (Zr). 

Anchor: The type of pipe support (restraint), which does not move the pipe translation (straight) and rotation (round). 

Backing Ring: a ring (ring) is used in welding to prevent the entry of weld spatter to the pipeline and to ensure full penetration weld on the wall in the pipe. 

Base metal: Metal that will weld, cut or disolder. 

Connection Branch: Branch pipe is added to the main pipe with or without the use of fitting. 

Carbon Steel: Steel with specific attributes based on the actual elements carbon (C) it. Blend elements may not exceed the following: mangan (Mn) 1.65% max., Silicon (Si) 0.60% max., Copper (Cu) 0.60% max. 

Cold Bending: The process of bending pipes up to a certain radius which is held in room temperature or with heating under the temperature change or transformation phase. Usually 5X radius elbow is the pipe diameter. 

Companion Flange: Flange for through the flange or valve and fitting with the ends of the flange. 

Deposited Metal: Metal fields have been added in the welding process. 

Header: Pipe or fitting some pipes which branch (branch) connect. 

Hot Bending: The process of bending pipes up to a certain radius of the heating to high temperatures in accordance with the work that summer. 

Hot Taps: The making of a connection pipe branch (branch) that was made during piping system in operating condition. 

Interpass Temperature: minimum or maximum temperatures that are required in the deposited metal Weld before starting to pass on the next multiple-pass welding. 

Piping: The components of piping system used to stream, distribute, mix, separate, issue, measure, control the flow of fluida. 

Piping Components: Elements for a suitable mechanical or through the system so that it becomes a strong piping for pressure fluida. 

Piping System: System piping that through with the design or condition of the same. 

Post Weld Heat Treatment (PWHT): The process of heat treatment after welding process to remove the remaining voltage that occurred during the welding process. 

Preheating: Heating to the base metal up to a certain temperature before welding started. 

Seamless Pipe: Pipe clamps are made without weld. Pipe manufactured through process pierching billet followed by rolling and / or drawing. 

Stainless Steel: Steel that has a blend of corrosion-resistant nature of the extraordinary. The main element is a blend Nickel (Ni) and Chromium (Cr).
