Current Grades Grade Code Minimum Yield (psi) E-75 E 75,000 X-95 X 95,000 G-105 G 105,000 S-135 S 135,000 Z-140* Z 140,000 V-150* V 150,000 U-165* U 165,000 Drill pipe tubes are furnished in the following API length ranges: Range 1:18-22 ft; Range 2:27-30 ft; Range 3:38-45 ft. FORGED STEEL FLANGES - CCTFbolt holes; (2) lack of contact with the fluid in the pipe often permits the use of inexpensive carbon steel flanges with corrosion resistant pipe or tubing; (3) in systems which erode or corrode quickly, the flanges may be salvaged for re-use. Socket-welding flanges contain a recess in the back of the flange to receive the end of the pipe

      • ApplicationsContinuous AustenitizationThe Influence of Prior ProcessesThe Influence of Induction Heating EquipmentTime and TemperatureContinuous QuenchingContinuous TemperingTempering MethodsConclusionHigh-strength steel tubulars are used extensively in applications ranging from bicycle frames to airframes. The oil and gas drilling industry has for years used quenched and tempered steel tubulars for well casing. As strength-to-weight ratios climb to reduce vehicle weight, the automotive industry is incorporating more heat-treated tubulars in such applications as door impact beams and seat frames.Butt Welding Pipe Fittings, Carbon Steel Pipe Fittings Butt Weld Fittings are pipe fittings used to change of direction of flow, to branch off, reduce pipe size or attach auxiliary equipment. Buttweld pipe fittings in carbon steel and stainless steel are the joining components that make possible the assembly of valves, pipes and equipment onto the piping system. How to Weld Hardened Steel eHowHardened steel is a form of high carbon steel that has been tempered through a heating process to make the metal more durable. Welding hardened steel can be tricky because the heat used in the welding process may cause the metal surrounding the weld joint to become brittle if proper heating and cooling methods are not used to prepare the metal. Passivation basics:Will this stainless steel rust?Nov 11, 2018 · In a word, chrome. Stainless steel is an alloy of iron with a minimum of 10.5 percent chromium. Chromium produces a thin layer of oxide on the surface of the steelthe passive layerthat prevents surface corrosion. Passivation is an essential process in the manufacture and quality assurance of varying grades of stainless steel.

        Larger diameter pipe (6 and over) 1) Prepare a patch plate as described in Fig. 10. Now drill a 1/2 hole in the center of the patch. Complete patch preparation by welding a 1/2" forged steel pipe coupling onto the patch directly over the drilled hole. (Fig. 10) 2) Clean and abrade underside of patch according to Metals Preparation Guide. SPECIFICATION FOR PIPEWORK WELDING, INSPECTION, Class 1 Arc Welding of Ferritic Steel Pipework BS 2633 1987 Class 2 Welding of Carbon Steel Pipework BS 2971 1991 Austenitic Stainless Steel Pipework BS 4677 1984 Approval of testing of welders for fusion welding of all comply with BS EN 287.

        Threaded Fittings General - Definition and Details - ASME

        Threaded fittings are normally made of cast gray or malleable iron, cast brass or bronze, or forged alloy and carbon steel. They are available in three pressure ratings:Class 2000, 3000 and 6000. NPT Thread. All fittings on this page are described, are provided with NPT thread, ASME B1.20.1. Welding technique of medium carbon steel and high carbon Jun 05, 2019 · Welding technique of medium carbon steel and high carbon steel. Welding capacity of medium and high carbon steels is low, this causes cracks at the end of the welding pool or in the heat-sensitive areas. In case this situation happens, it requires welders to preheat and local heat the areas of welds. Preheating is at a temperature of 250 - 300 Why is preheat used when arc welding steel, and how is it Frequently Asked Questions. Preheating is the process applied to raise the temperature of the parent steel before welding. It is used for the following main reasons:The slower cooling rate encourages hydrogen diffusion from the weld area by extending the time period over which it is at elevated temperature (particularly the time at

        Carbon Steel Pipe - an overview ScienceDirect Topics

        Carbon steel pipe is used as the base pipe of bimetallic combination tubing, which has an internal liner made of stainless steel, titanium alloy steel, copper or aluminum, and so on. This type of tubing has high mechanical performance, high corrosion resistance, high weldability, high operational convenience, and high
