Product Description The pipe cap is a pipe fitting welded on the pipe end or installed on the external thread of the pipe end to cover the pipeStainless steel pipe cap is also called plug or head. The pipe cap includes the design of convex pipe cap, conical shell, reducing section, flat cap and tight mouth.Stainless steel material: 304 304L 316 316L 321 2520 310, 317, etcDiameter: DN15-DN1200Wall thickness: SCH5-SCH160Standard: ASME DIN JIS BS GB/T JB SH HGApplications: water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproof treatment, pipes, etc., pipe fittings welded on the pipe end or installed on the external thread of the pipe end to cover the pipe. It is used to close the pipeline and has the same function as the plug.Packaging: wooden box, carton service: technical consultation, installation guidance, etcThe r part of the dished pipe cap shall not be spliced, which will reduce the thickness and high stress.During splicing, only radial and circumferential weld directions are allowed. This requirement may be cancelled in the future for large pipe caps. The splicing distance shall be more than 3 δ, It shall not be less than 100mm (the welding heat affected zone is a high stress zone, and the chemical composition in this zone will be burned. Therefore, it is necessary to avoid the high stress zone, which is related to the thickness. According to practical experience, the stress attenuation length is greater than 3 δ, And not less than 100mm). However, refrigeration equipment is difficult to meet this requirement, which has its particularity.100% radiographic or ultrasonic testing shall be carried out on the splicing weld of the formed head after splicing, and the qualification level shall follow the equipment shell. The inspection level and proportion of the final formed weld are the same as that of the equipment shell, which is high waste.For example, if the equipment shell is 20% tested, III is qualified. The butt weld and final weld of the bulkhead are also qualified as III, and the welding joint coefficient is 0.85;If the equipment shell is 100% tested, II is qualified. The butt weld and the final weld of the bulkhead are also II qualified, and the welding joint coefficient is 1Therefore, although the bulkhead splicing is 100% tested, the qualification level is different, which follows the equipment shell.But pay attention to the process and manufacturing process:The correct method is: blanking (scribing) - small plates assembled into large plates - forming - NDTIf the inspection is not conducted before forming, it is wrong to ensure that it is still qualified after forming. That is to say, NDT refers to the final NDT.Typeweld carbon /stainless steel stub pipe fitting ends cap dimensionsSize1/2"-72"(DN15-DN1200)ConnectionweldingTechnicforgedVarietiesSCH20, SGP, STD, SCH40, SCH80, SCH160Material carbon steel ,stainless steel WPBA234,Q235,20#,A420 A403-WP304,A403-WP316,A403-WP316L,A403-WP317,A403-WP321 etc.StandardBS, DIN ,JIS,etc. ANSI B16.9/16.28, ASTM,API 5L, DIN2605/2615/2616, JIS P2311/2312 ASME B36.10M---1996Qualityfirst gradeCertification ISO9001 - 2000, CE, SGS, etc. Application petroleum, electricity, chemicals, natural gas, construction, shipbuilding and other fields because of its high pressure, high temperature, etc Packaging wooden case,pallet ,container or in accordance with the requirements of customersPrinciple quality first,customer first,credit first,PaymentL/C T/T D/P...Surface treatmentBlack rust-proof oil, transparent oil, hot galvanizingNotesThe bevel can be made according to the special requirements of the customersOtherswe can also produce the products accordance with the requirements of customers
