The high temperature oxidation resistance of 347 is similar to that of 304 stainless steel. Useful to 1500°F. Often in many product forms, the grain size and carbon content can meet both the 347S and 347H requirements. Appropriate weld fillers are AWS ER347 bare wire and E347 covered electrodes. 4140 Alloy Steel Tubing - 4140 Heat Treated Steel Tubing Alloy steels or high-tensile steels are a low-carbon steel, or steels at the lower end of the medium-carbon range. Alloy steel has additional alloying ingredients in order to increase their strength, wear properties or specifically tensile strength. These alloying ingredients include chromium, molybdenum, silicon, manganese, nickel and vanadium.
- IntroductionMethodologyResults and DiscussionConclusionReferences1.1 Offshore Pipeline Material
Pipelines in offshore platform are made up of various types of materials. Selection of material relies upon certain considerations such as cost, functional requirement, operating conditions of pressure and temperature, corrosion rate and so forth [1-2]. Since there are varieties of pipelines in offshore platform1.2 Plain Carbon Steel
Carbon steel is a material consisting of carbon as its main alloying element. Carbon steel is made up of iron (Fe), carbon (C), phosphorus (P), manganese (Mn), sulphur (S) and silicon (Si) . Currently in the worldwide market, carbon steel is being manufactured and used in large quantities for heavy industries1.3 A333 Grade 6 Low Carbon Steel Pipe
Based on the comprehensive data in Table 1, material type A333 Grade 6 was chosen to analyse the Cold Drawn Seamless Tubing - CDS Steel Tubing Uniform Cold Drawn Seamless Mechanical Tubing (CDS) is a cold drawn 1018/1026 steel tube which offers uniform tolerances, enhanced machinability and increased strength and tolerances compared to hot-rolled products. Produced from hot rolled 1026, the cold drawing process increases the tube's physical properties and offers better tolerances and reduced machining allowances over hot finish seamless. Better Pipe and Tube - T&H LemontHigh Frequency Induction Welding. In the HFI tube welding process, high frequency current is induced in the open seam tube by an induction coil located ahead of (upstream from) the weld point, as shown in Fig. 1-1. The tube edges are spaced apart when they go through the coil, forming an open vee whose apex is slightly ahead of the weld point. Carbon steel square tube - qiyuangtchinaCarbon steel square tube. . . Rectangular tube is a name for square and rectangular tubes, that is, tubes with equal and unequal sides.It is made of strip steel after processing.The strip is generally unpacked, flat, crimped, welded into a round pipe, and then rolled into a square pipe by the round pipe and then cut into the required length.
1946. During 1950, the idea of HF welding of steel tubes was intensified, and applied in cables and profile production. The condi-tions for HF welding were made. Figure 1.1 shows a detail of outgoing part of generator for HF inductive welding of steel tubes where welding rollers, impeder and the steel tube itself can be seen. HOLLOW STRUCTURAL SECTIONS - J & R Welding In the tube mill, at steel strip (1) is formed continuously around its longitudinal axis to produce a round tube. This is done by moving the strip through a progressive set of rolls (2-6). The strip edges (7) are heated by either high frequency induction or contact welding and then forged together by weld rolls to create a continuous Stainless Steel Tube SpecificationsSteel Tubing, Welded, Corrosion and Heat Resistant 18 Cr; 11 Ni, (Cb + Ta)(SAE 30348) Thin Wall.

Ultra-Strength Carbon Steel(AHSS) Round Tubes. The same steel used in automobile bodies, this AHSS (advanced high-strength steel) allows you to fabricate high-strength parts using thinner material than you could with other types of steel. It is formable, weldable, and more economical than alloy steel.
