Field fabrication and installation of Piping systems

Dependent on the external dimensions and wall thickness there are different methods of producing welded pipes and tubes The welded pipes are produced by three types of welding processes Electric Resistance Welding ERW Fusion Welding EFW and Double Submerged Arc Welding DSAW Pipe Mill Welding cutting and fabrication of large scale pipe for cross country and subsea material transfer Power Generation Equipment consumables and automation solutions for carbon based bio fuel and renewable fuel generation Shipbuilding Advanced processes and automated solutions for critical and unique shipbuilding requirements USB2 US10/ USA USB2 US B2 US B2 US B2 US A US A US A US B2 US B2 US B2 AuthorityThe job of a pipe welder entails various functions given below is an example of job description that details the major duties tasks and responsibilities of the role Assemble and install metal pipes and pipe fittings for stainless and carbon steel projects Use clamps brackets and hangers to secure pipes to structures Pipe welding has four positions 1G the horizontal rolled position In this position the pipe is horizontal and it is being rolled so that you the welder are actually in a flat position relative to the pipe It& 39 s the easiest pip welding welding position 5G the horizontal fixed position 5G is a lot like 1G in that the pipe is in the Pipe welding certifications You can train in various different pipe welding techniques and earn certifications for each of the different pipe welding positions However as mentioned previously a 6G welding certification is really appealing to many welders and employers because of the high skill level which the technique requires The vector stencils libraries " Pipes 1" and " Pipes 2" contain 28 and 48 pipe tubing and fitting symbols respectively < br> " A fitting is used in pipe plumbing systems to connect straight pipe or tubing sections to adapt to different sizes or shapes and for other purposes such as regulating or measuring fluid flow The term plumbing is generally used to describe conveyance of water gas or Mar 12 In HFW/HFI welding a high frequency current is used to create weld joints Whereas in EFW welding process the external high energy electric arc is used to create a weld joint Once the welding is done the excess weld material from outside and inside of the pipe is removed with the help of trimmer tools Explore our high quality Cutting and welding Carriages Collection such as Torch Runner Track Cutting Machine Rail Runner Welding Carriage Arc Runner Welding Carriage & much more!

The Basics of Welding Certifications and Test Positions

Mar 01 Just like structural welding positions pipe welding certifications come in two joint types F is for a fillet weld G is for a groove weld 1G Pipe Welding Certification Position The 1G pipe welding certification position is a pipe in the horizontal position and the pipe is rolled when welding This is basically welding in the flat position This booklet is a guide to welding pipe with Shielded Metal Arc Welding SMAW and double ending pipe using automatic welding Lincoln Electric supplies electrodes power sources automatic and semiautomatic wire feeders submerged arc wire and flux which are the industry standards for pipeline construction around the world This engineering drawing present weld type symbols and fillet weld symbols < br> The weld type symbol is typically placed above or below the center of the reference line depending on which side of the joint it& 39 s on The symbol is interpreted as a simplified cross section of the weld < br> " Fillet welding refers to the process of joining two pieces of metal together whether they be perpendicular The Track Welding Carriage With Oscillator is a track welding carriage designed to produce butt and fillet welds with or without oscillation The carriage can work in PA flat PB horizontal vertical PC horizontal PD overhead horizontal vertical PE overhead PF vertical up and PG vertical down welding positions Feb 06 The submerged arc welding SAW process or a combination of gas shielded tack welding with downstream submerged arc welding is widely accepted as the standard method for welding of the large diameter pipe The fusion welding processes are also used in the production of spiral and longitudinal welded pipe of high alloy stainless steels LIZARD is a portable programmable welding carriage designed to produce high quality welds using MIG/MAG welding torches Friction drive and control loop feedback mechanism provide speed stabilization in all positions A very important optional feature of LIZARD is oscillation attachment The pipe welding apparatus 20 comprises a motor driven main welding carriage 28 and a welding assembly 30 carried thereon [] In a typical installation of the pipe welding apparatus 20 the main carriage 28 is mounted on an annular band track or guide 32 which is supported about the first pipe section 22 The Track Welding Carriage With Oscillator is a track welding carriage designed to produce butt and fillet welds with or without oscillation The carriage can work in PA flat PB horizontal vertical PC horizontal PD overhead horizontal vertical PE overhead PF vertical up and PG vertical down welding positions Other sites or plants for example can have their own piping specifications and they are NOT interchangeable To use the piping specification reference must first be made to the Process and Instrument Diagram Identify the section of pipe in the PID and a line number will be quoted e g 12 FW 1CS1P which is interpreted as follows

Types and process of welding pipe ERW LW CW SAW pipes

Welding is a fabrication process whereby two or more parts are fused together by means of heat pressure or both forming a join as the parts cool Welding is usually used on metals and thermoplastics but can also be used on wood The completed welded joint may be referred to as a weldment Some materials require the use of specific processes Nov 04 Introduction to Pipe Support A pipe support is a designed element that transfer the load from a pipe to the supporting structures The load includes the weight of the pipe the content that the pipe carries all the pipe fittings attached to pipe and the pipe covering such as insulation The four main functions of a pipe support are to anchor WELDING can cause fire or explosion Remove all flammables within 35 ft 10 7 m of the welding arc If this is not possible tightly cover them with approved covers Do not weld where flying sparks can strike flammable material Protect yourself and others from flying sparks and hot metal Be alert that welding sparks and hot materials from There is a wide variety of types of materials ferrous and nonferrous produced on tube/pipe mills With that we find a wide host of " types" of welding to match the product line mix be it ERW Electric Resistance Welding HF High Frequency—both coil and contact TIG MIG LASER and PLASMA just to name a few Shanghai Huawei Welding & Cutting Machine Co Ltd was incorporated at which is the leading enterprise in welding & cutting equipment industry Our featured products are flame cutting machine CNC cutting machine welding tractor beveling machine electrode dryer and oven tion regarding location type size and extent of all welds shall be clearly shown on the drawings The drawings shall clearly distinguish between shop and field welds 2 2 2 Joint Welding Sequence Drawings of those joints or groups of joints in which it is especially impor tant that the welding sequence and technique be carefully2 Fittings on piping 2 1/2 inches and larger shall be extra heavy butt welding type Flanges shall be lb welding neck type Extra strong Weld o lets Thread o lets or shaped nipples may be used only when takeoff is one third or less nominal size of main 3 Screwed fittings around traps and for piping 2 inches and smaller shall be lb Sep 30 LANL Standard Drawings and Details either 1 depict required format/content or 2 are templates that are completed by a Design Agency LANL or external AE for a design drawing package in a manner similar to specifications A device for butt welding pipes 99 A B comprises a guide element 17 which can surround and can be fixed to one of the ends of the pipes and a carriage 1 movable along the said guide element and having powered means 25 for moving it along the guide element 17 a welding torch 90 means 29 for feeding it and means 26 for supporting the said welding torch 90
