Galvanized pipe end is sprayed with cold galvanizing internally and externally; Pipe is then gravity fed to the N.A.P. Universal Welder; Outlets welded to galvanized pipe are galvanized cold sprayed; Weld coupons are removed, bagged and stored; Blast cannon removes all dust and dirt from inside of pipe; Welds are die penetrate and developer tested Field fabrication and installation of Piping systemsShop fabrication is, generally speaking, any pipe, fittings and components that are assembled by welding into spool assemblies at the fabricator's facility. The spools are then labeled with an identifier and transported to the job site for installation. Hydrostatic testing of fittings and valves - Pipelines Jan 10, 2019 · Section 841.3.1 states that "All piping systems.." shall be tested except for pre-tested fabricated assemblies - see below. Once you tie-in those non welded (i.e. flanged or screwed) connections you then need to test those connections to a leak test of the max pressure available.

A pipe can be defined as a tube made of metal, plastic, wood, concrete or fiberglass. Pipes are used to carry liquids, gases, slurries, or fine particles. A piping system is generally considered to include the complete interconnection of pipes, including in-line components such as pipe fittings and flanges. Introduction to Welded Pipe Manufacturing - The Process
- Electric Resistance Welding (ERW) ProcessSubmerged Arc Welding (Saw) ProcessElectric Flash Welding ProcessLap Welding ProcessPipes, valves and fittings Dairy Processing HandbookPermanent joints are welded (Figure 6.8.1). Where disconnection is required, the pipe connection is in the form of a threaded union with a male end and a retained nut with a joint ring in between, or a clamped union with a joint ring (Figure 6.8.2). The union permits disconnection without disturbing other pipe-work.

There are two ways to weld pipe 1st is with filler metal and 2nd is without filler metal. Submerged Arc Welding process is with filler metal welding whereas ERW/EFW and HFW are no filler welding methods to weld the pipe. SAW pipes are further classified as straight seam and spiral seam pipe. Poly Pipe Electrofusion Fittings Electro fusion Poly Electrofusion is an electrical fusion process by which an external sleeve fitting incorporating an element is installed to poly pipe or fittings and with application of electrical current they are welded to each other. The current applied to the fitting is regulated and supplied by an electrofusion welding machine, which controls the amount of voltage, amps and welding time supplied to a fitting, in order for it to weld
Custom Weld System. This precise technology is a great welding option for low heat effect and thermal distortion control. We also employ laser welding on complicated, difficult to Welded ducting components BerlinerLuft.Technical specifications SHEET STEEL.
