  1. www.steeljrv.com sales@steeljrv.com Execution Standard of Seamless Steel Pipes 2018-06-10 Industry News News   A seamless steel pipe, as the name suggests, is a steel pipe without a seam or a weld-joint. Seamless pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. Seamless pipe is thought to be able to withstand higher pressure, higher temperatures, higher mechanical stress and a corrosive atmosphere. It can be found in a wide range of applications such as in oil and gas, refinery, petrochemical, chemical, fertilizer, power, automotive, bearing, mechanical and structural. The production of our seamless pipe is tightly regulated and all of the steel pipes we stock have been fully tested to international standards to ensure we only supply the highest quality products.

Please refer to the specific Standard or Specification or contact us for more details. 1. SCOPE: 1.1 This specification covers sesamless and welded steel line pipe. It includes standard-weight and extra-strong threaded line pipe. It includes standard-weight and extra-strong threaded line pipe; and standard-weight plain-end,regular-weight plain-end, special plain-end, extra-strong plain-end, special plain-end, extra-strong plain-end pipe; as as well as bell and spigot and through-the-flowline(TFL) pipe.The purpose of this specification is to provide standards for pipe suitable for use in conveying gas, water, and oil in both the oil and natural gas industries.1.2 Dimensional requirements on threads and thread gauges, stipulations on gauging practice, gauge specifications and certification, as well as instruments and methods for inspecition of threads are given in API Standard 5B and are applicable to products covered by this specification.Grades covered by this specification are A25, A, B, X42, X46, X52, X56, X60, X65, X70, and X80 and grades intermediate to the Grades X42 and higher listed (see note). The chemical composition and mechanical properties of intermediate grades that are subject to agreement between the purchaser and the menufacturer must be consistent with the corresponding requirements for the grades to which the material is intermediate. Note :The grade disignations used herein for Grades A and B do not include reference to the specified minimum yield strength. Other grade designations used herein comprise the letter A or X followed by the first two digits of the specified minimum yield strength.1.3 Pipe manufactured as Grade X60 or higher shall not be substituted for pipe ordered for Grade X52 or lower with-out purchaser approval.1.4 Although plain-end line pipe meeting this specifiecation is primarily intended for field makeup by circumferential welding, the www.steeljrv.com sales@steeljrv.com

  8. www.steeljrv.com sales@steeljrv.com manufacturer will not assume responsibility for field welding.1.5 For regular-weight and special plain-end pipe(special weight) whown in Tables 6A, 6B, and 6C and for standard weight threaded pipe larger than nominal size 12, the size designations used herein are outside diameter sizes. For all other pipe, the size designations are nominal pipe sizes. In the text of this specification, pipe size limits(or size ranges)are outside diameter sizes except where stated to be nominal. These outside diameter size limits and ranges also apply to the corresponding nominal sizes.1.6 Class Ⅱ steel is rephosphorized and problbly has better threading properties than Class I. Because Class Ⅱ has higher chemical properties than Class I, it may be somewhat more difficult to bend.1.7 U.S. customary units are used in this specification; metric(SI) units are shown in parenthese in the text and in many tables.

The hydrostatic test shall be applied, without leakage through the weld seam or the pipe body. Nondestructive electric test shall be made to make sure that the full volume of the pipe must be in accordance with the standard. The purchaser shall have the right to perform any of the inspections and tests set forth in this specification where deemed necessary to ensure that the pipe conforms to the specified requirements. 1.1 This specification covers seamless and welded black and hot-dipped galvanized steel pipe in NPS 1/8 to NPS 26 [DN 6 to DN 650] (Note 1), inclusive, with nominal wall thickness (Note 2) as given in Table X2.2 and Table X2.3. It shall be permissible to furnish pipe having other dimensions provided that such pipe complies with all other requirements of this specification. Supplementary requirements of an optional nature are provided and shall apply only when specified by the purchaser. Note 1—The dimensionless designators NPS (nominal pipe size) [DN (diameter nominal)] have been substituted in this specification for such traditional terms as “nominal diameter,” “size,”and “nominal size.” Note 2—The term nominal wall thickness has been assigned for the purpose of convenient designation, existing in name only, and is used to distinguish it from the actual wall thickness, which may vary over or under the nominal wall thickness. 1.2 This specification covers the following types and grades: 1.2.1 Type F—Furnace-butt-welded, continuous welded Grade A, 1.2.2 Type E—Electric-resistance-welded, Grades A and B, and 1.2.3 Type S—Seamless, Grades A and B. Note 3—See Appendix X1 for definitions of types of pipe. 1.3 Pipe ordered under this specification is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas, and air lines. It is suitable for welding, and suitable for forming operations involving coiling, bending, and flanging, subject to the following qualifications: 1.3.1 Type F is not intended for flanging. 1.3.2 If Type S or Type E is required for close coiling or cold bending, Grade A is the preferred grade; however, this is not intended to prohibit the cold bending of Grade B pipe. 1.3.3 Type E is furnished either no expanded or cold expanded at the option of the manufacturer. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard.

Seamless steel pipe transport fluids including water, natural gas, waste and air. Three manufacturing methods exist to produce steel pipes. Seamless steel pipes are produced using an extrusion mold. Welded steel pipes are produced by rolling a sheet of steel into a tube and welding the seam. Seamless steel pipes are less expensive. The third method is casting. Molten steel is poured into a casting mold. Our steel pipes and tubes are the preferred choice for processes under the following conditions: – high temperatures – aggressive media (e.g. acid and lye) – and/or high pressure We have a team of experienced professionals with years of experience in manufacturing. ASTM A210/ASME SA210 Seamless Medium-Carbon Steel Boiler and Superheater Tubes ASTM A210/ASME SA210 Standard Specification for Seamless Medium-Carbon Steel Boiler and Superheater Tubes. ASTM A210 is the standard covers seamless medium-carbon steel boiler and superheater tubes.

These tubes are predominantly www.steeljrv.com sales@steeljrv.com

  48. www.steeljrv.com sales@steeljrv.com used in the constructin of chemical plant, vessels, pipework and for general mechanical engineering purposes. They are designed to meet high performance requirements. Normally there are no limiting vaiues or the maximum permissible working pressure of these tubes. The permissi l working temperature shall not exceed 300℃ are specified in Appendix A.) The limits of application and other specifications given in this standard shall apply except in cases here other specifications are contained in codes of practice for specific fields of application, e.g. the Technische Regeln fur Dampfkessel (TRD) (Technical rules on steam boilers) or the Technische Regeln fur Druckbehalter (TRB) (Technical rules on pressure vessels), AD-Merkblatter (AD Instrucation sheets).
