Tenders Are Invited For Heat Connection And Fibrin Heat Connection 1

1) The Heating Network Connection Made In The Technology Of Pre -Insulated Pipes With A Diameter Of 2X042.4/110 (2Xdn32), In The Field And In Traditional Technology With A Diameter Of 2Xdn32, In Building. Located Between The Characteristic Points Z10 And Z1oa (In Accordance With The Doc. The Node, Through The Input Pipes, Where It Will Be Completed With Ball Valves, To Be Remembered With Dn32 Diameter (2 Pcs). The Heat Node, Which Is A Separate Study And Being The Subject Of The Proceedings Within Part Ii) .6) The Pipelines Of The Pre -Insulated Connection, Introduced To The Building, Will Be Completed With Thermocurntive Tips. Pipelines Made In Traditional Technology, Conducted Inside The Building, To The Shut -Off Valves In The Node Room, Should Be Insulated With Pur Tubes, In A Pvc Foil Coat 7) A Heating Network Connection In The Technology Of Pre -Insulated Pipes With Standard Thermal Insulation Thickness Is Designed. Pre-Insulated Pipes Are Adapted For Direct Laying In The Ground And Can Work Under The Following Conditions:- Working Pressure 1.6 Mpa,- Working Factor Temperature 130 ° C With The Possibility Of Periodic Lifting Up To 150 ° C, 8) The Pre-Insulated Pipe Consists Of Three Integral Parts:- Steel Pipe- The Polyurethane Foam Polyethylene.9) The Correct Wire Pipe Is A Suture Pipe With A Welded Connector Strength Coefficient Z = 1 Made Of Steel St 37.0 According To Din 1626.10) Thermal Insulation Is A Polyurethane Foam With A Factor Of A. = 0.027 W/Mk. The Foam Meets The Requirements Of En 253 And Pn-85/B-02241.11) The Outer Pipe Is Made Of Hard Hdpe Polyethylene Ensuring Effective Protection Of Foam And Steel Pipe Against Moisture And Mechanical Damage. 12) Pipes Are Supplied In Simple Sections Of 12 Meters (6 Meters). The Connections Of The Pipes Are Insulated With The Help Of The Thermocurkinous Meattressed By Radiation. 13) Heating Connection With Pre -Insulated Pipes Is Designed To The Wall Of The Building. Further Connection Will Be Made In Traditional Technology With Steel Pipes Without A Seam, According To Pn-80/H-74219.14) Cutting And Venting Fittings-Welded Ball Valves, Manometric Chanterelles Cat. Armament, Which Is Why In These Places Excavations Must Be Made By Hand. 16) Appropriate Sand Bed Under Pipelines And Backfill With Sand And Soil Of Pipelines, Causes Restrictions On Their Thermal Elongations. On The Knees That Take Over The Thermal Elongations Of The Pipelines, The Appropriate Compaction Of The Bedding And Backfill Of The Pipeline (Or Arrangement Of The Compensation Mat) Should Be Made In The Area Of ​​The Compensation Zone Depending On The Length Of The Compensated Section And The Outer Diameter Of The Pre -Insulated Pipe. The Appropriate Dimensions Of The Excavation And Widening Of The Excavation On The Collapse Should Be Made In Accordance With The Recommendations Of The Pre -Insulated Pipes Manufacturer. After The Pipeline Is Made, The Heat Pipeline Should Be Secured By The Arrangement Of The Warning Tape. 17
