Product Description

Product introduction:Best quality paralleled upsetting couplers with black surface type and light surface type as client choose, it is super rebar coupler with raw material 40Cr with higher strength, it also can be designed as different out diameters and length and also the thread pitch. We always have some stocks for our standard sizes.Product details:Name:Parallel   Upsetting Rebar couplers (U type)Used for Rebar:HRB400/Grade 65/ and so on with rebar yield strength same as 500Mpa   or lower than that.Raw Material:S45C -yield strength 420Mpa, Tensile strength: 600-650MPaSize:16mm/18mm/20mm/25mm/28mm/32mm/36mm/40mmPacking:By bags and pallets packing, or wooden case packing as required (25KG   smaller packing, 1700KG per pallet)Sample:Free existing samples for checking dimension and qualityProduction time:15-40 days based on different quantity after receive the prepaymentShipping Port:Xingang,Tianjin Port,  Shanghai   Port, China.Payment Terms:TT / LCCertificate:ISO/ CESIZE (mm)Out Diameter (mm)Length (mm)Pitch (mm)N.W    (KG)PACKING IN ONE BAG  (NOS)1 BAG WEIGHT (KG)Approvals/ Certificate1626402.50.08325020.75CE / ISO1829442.50.11620023.20CE / ISO2032483.00.15913220.98CE / ISO2236523.00.21412125.89CE / ISO2540603.50.3088024.64CE / ISO2844663.50.4045622.62CE / ISO3250724.00.6154225.83CE / ISO3656804.00.8942724.13CE / ISO4062904.01.1362528.40CE / ISO1.Super Upsetting Couplers IntroductionUpsetting technology is using a parallel-thread mechanical splicing system designed for the connection of 16mm to 40mm reinforcing bars in the construction working site. This system is using cold upsetting and Metric thread Cutting process which can make sure about the rebar connection tensile strength make the bar break.This Best quality parallel upsetting couplers is in compliance with China standard UK standard, USA standard and also other international standards. Its very popular in the rebar connection filed 2.This Black surface upsetting couplers Features and advantagesa.This technology will not reduce the rebar diameters and  it will enlarge itb.Fast Installation without torque wrench operationc.Assemble easy by visual inspectiond.It is Standard ISO parallel Metric Thread used for most of the countries.e.Standard coupler can be used both for standard splice and position splice.f.This mechanical connections are quicker, safer and mover convenient ways than old type lap splicing or welding splicing. 3.Rebar Processing Working Stepsa.Cutting the rebar end to make it flatb.Enlarge the rebar diameter by cold upsettingc.Making the parallel thread by cuttingd.Connect the rebars and make sure the barbreak4.This super couplers Application situtationsa.Splicing method as below:Standard Connection                                                              Position Splicing 1Position Splicing 2                                                              Transition Splicingb.Typical applications   Column                                                                                  Bored Piles   Waiting Rebar                                                                           Wall, Shell                                                                       Beam5.Technical Dataa.Applicable Standards: JGJ107-2010, UK standard of BS8110, USA standard of ACI318, VN standard of TCVN8163 and other international standardsThe couplers are produced strictly under tested by the thread gauge and calipers.b.Raw materialCouplers are produced by the raw material of 40Cr, correspond to international standards of JIS: SCr440, ASTM: 5140, ISO: 41Cr4.Chemical composition: C:0.37~0.44    Si:0.17~0.37   Mn:0.50~0.80   Cr:0.80~1.10 Ni:≤0.30  P:≤0.035  S:≤0.035  Cu:≤0.30Mechanical Properties: Yield strength≥ 785MPa, Tensile Strength: ≥980MPa.c.Picturesd.Coupler Tensile strength comparison with common Splicing standardsSize1620253240OD (mm)2632405062Thread larger Dia (mm)20.0024.0030.0036.0045.00Coupler Cross section area (mm2)216.91352.06550.1946.081429.3640Cr Min Tensile Strength by pipe    (N/mm2)860860860860860Coupler Load (KN)186.54302.77473.09813.631229.25Rebar cross-section area (mm2)201.1314.2490.9804.21257BS 8110  3.12.8.16.2 108% Fy,   with 500 rebar load(KN)108.59169.67265.09434.27678.78ACI318 12.14.3.4 125%Fy(Type 1) with 500 rebar load(KN)125.69196.38306.81502.63785.63ACI318 21.2.5&6  1.5% Fy,   125%Fy,100% FU,(Type 2) with 500 rebar load(KN)138.76216.80338.72554.90867.33Coupler Load(KN) with BS 8110, ACI 318 requirement RemarkAboveaboveaboveaboveabove
