ASTM A335 Chrome Moly Pipe

Chrome Moly Pipe has become a standard in the power generation industry and the petrochemical industry, not only because of its tensile strength, corrosion resistance and high-temperature strength, but also because of its cost-effectiveness. Grades P-11, P-22 – P-91 & P-92 are prevalent grades for the power industry, while P-5 & P-9 are the grades utilized in major refinery processing. ASTM A335 P9 alloy steel pipe ASTM A335 P11 alloy steel pipe ASTM A335 P22 alloy steel pipe ASTM A335 P91 alloy steel pipe ASTM A335 P92 alloy pipes ASTM A335 P5 alloy steel pipe Sunny Steel Supply stocks a full range of the following A335 pipe grades: Main grades:  ASTM A335 P5, P9, P11, P-22, and P91 Size range: NPS 1/4'' to NPS 24'' Wall Thickness - Schedules 40 through 160, STD, XS, XXS.

Steel pipe world standards

Pipe manufacturing refers to how the individual pieces of pipe are made in a pipe mill; it does not refer to how the pieces are connected in the field to form a continuous pipeline. Each piece of pipe produced by a pipe mill is called a joint or a length (regardless of its measured length). In some cases, pipe is shipped to the pipeline construction site as “double joints”, where two pieces of pipe are pre-welded together to save time. Most of the pipe used for oil and gas pipelines is seamless or longitudinally welded, although spirally welded pipe is common for larger diameters. 1.

Orifice Flanges

Orifice flange for run installation should be so constructed, machined and attached to the that the inner surface of the passage extends through the orifice flange so that there is no recess at the orifice plate. Orifice flanges are used instead of the standard pipe flanges when orifice plate or flow nozzle is used. The basic purpose for this is to measuring the flow rate of either gases or liquids in the respective pipeline. These flanges are used in various industrial applications and are available in various sizes and materials. Orifice Flange manufacturer Sunny Steel supplies Orifice Flanges, Plate Flanges, Datasheets and dimensional information ANSI 300 Flange - Orifice, Weld Neck, ANSI Class 300, B16.36 (in) ANSI 400 Flange - Orifice, Weld Neck, ANSI Class 400, B16.36 (in) ANSI 600 Flange - Orifice, Weld Neck, ANSI Class 600, B16.36 (in) ANSI 900 Flange - Orifice, Weld Neck, ANSI Class 900, B16.36 (in) ANSI 1500 Flange - Orifice, Weld

Difference between ERW, SSAW, LSAW

Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).  ERW pipes The following table several steel pipes process characteristics and quality of performance comparison: High frequency straight seam welding ( ERW ) method is divided into two forms of induction welding and contact welding, hot-rolled wide volume as raw material, pre-curved, continuous molding, welding, heat treatment, sizing, straightening, cutting, etc. process, compared with the spiral weld short, high dimensional accuracy, uniform thickness, surface quality, pressure advantages, but the drawback is that only the production of small and medium-caliber thin-walled tube, weld easy to produce gray leaf spot, not fusion
