1.3 Bazele dimensionarii si executiei 1.3 Design and construction principles

Piesele schimbatoarelor de caldura, care se protejeaza, trebuie astfel proiectate si fabricate, nct si poate fi prevazute cu protectia de suprafata, fara alte lucrari ulterioare sau modificari.

The heat exchanger parts to be protected must be designed and manufactured so that they can be given surface protection without additional reworking or alteration.

Pentru a putea ndeplini conditiile cerute, este necesara colaborarea strnsa ntre producatorul de schimbatoare de caldura si executantul protectiei de suprafate-chiar n stadiul de proiectare.

In order to satisfy the conditions, close cooperation between the manufacturer of the heat exchanger and the manufacturer of the surface protection is already required during the planning stage.

Pentru a stabili modul adecvat de protectie a suprafetelor, trebuie sa se faca cunoscute executantului protectiei, datele tehnologice exacte ale schimbatorului de caldura (specificatia tehnica).

In order to determine the suitable type of surface protection, the bidder or manufacturer of the surface protection must be informed of the exact technical data of the heat exchanger (technical specification).

Executantului protectiei de suprafata trebuie sa i se nmneze nca din stadiul de oferta desenele (inclusiv detaliile) pieselor care urmeaza a fi protejate. Piesele care se prevad cu protectie de suprafata se vor marca explicit n desene.

In addition, the manufacturer of the surface protection must be given the drawings (incl. details) for the parts to be protected already during the offer stage. The parts to be given surface protection must be clearly labeled in the drawings.

Pentru acoperire se folosesc materiale duroplastice stratificate, care se aleg in functie de mediul de lucru.Exemplu: Expunere la apa de racire.

Duroplastic coating materials must be used for the coating and selected specifically for the medium.

Exemplu: Expunere la apa de racire.

Tevile si placa tubulara: de ex. Skaphen tip Si57E

Camera de distributie, capacul camerei de distributie, capul flotant, capacul mare de ex. Saekaphen tip Si57E.

Grosimea stratului conform prescriptiei producatorului.

Example: Cooling water exposure

Tubes and tubesheets: e.g. Skaphen type Si57E

Pre-chamber, pre-chamber cover, floating head, floating head cover: e.g. Skaphen type Si57EG, Prodotex-DR.

Layer thicknesses according to the manufacturer instruction.

Pentru utilizarea unor materiale de acoperire echivalente ale altor producatori trebuie prezentata o aprobare a managerului de proiect OMV / Petrom (privind conductibilitatea termica suficienta, referinte, etc).

For the use of equivalent coating materials from other manufacturers, approval must be obtained from the OMV project manager (sufficient thermal conductivity, references, etc.).


2.0 DETALII CONSTRUCTIVE 2.0 CONSTRUCTION DETAILS Premiza pentru o protectie perfecta a suprafetelor este executarea pieselor schimbatoarelor de caldura - din punct de vedere constructiv si al tehnicii de sudura- corespunzator urmatoarelor detalii:

The prerequisite for proper surface protection is structural and welding-related design of the heat exchanger parts according to the details listed below.

2.1 Acoperirea 2.1 Coating area Partea interioara a tevilor aferente fasc.tubular Placa tubulara pe partea camerei de distributi Camera de distributie Capacul camerei de distributie Partea interioara a capului flotant

The inside of the bundle tubes The tube-sides of the tubesheets The pre-chamber The pre-chamber cover The inside of the floating head

2.2 Instructiuni de fabricatie 2.2 Manufacturing rules Suprafata ce urmeaza a fi acoperita trebuie sa nu

prezinte striuri de tragere, dublari si alte defecte de laminare.

Se vor utiliza tevi din otel de precizie, fara cusatura, trase la rece.

The surface that is subject to coating must be free of scratches, laminations and other rolling flaws.

Seamless cold-drawn precision steel tubes must be used.

Capetele tevilor vor fi astfel sudate in placa, incat prin cordonul de sudura, sa se creeze o zona neteda de trecere catre placa, cu o raza de 1,5 mm (vezi Anexa 3, fig.1). Cordoanele de sudura trebuie sa nu prezinte pori, despicaturi, fisuri, muchii, cruste de arsura, resturi de material de sudura sau incluziuni de zgura. Se va evita o

The tube ends must be welded into the tubesheet so that the weld seam creates a smooth transition to the tubesheet with a radius1,5 mm (see 0, fig. 1). The weld seams must not have any pores, gaps, cracks, sharp curbs, undercuts, welding material splashes or slag inclusions. A significant elevation of the weld seams must be avoided.

Daca este prescrisa o mandrinare (cilindrare) a tuburilor, aceasta operatie se va executa dupa efectuarea sudarii tevii.

If tube expanding is specified, this must take place after the tube welding.

Acoperirea fasciculelor de tevi se va executa numai dupa finalizarea tuturor operatiilor mecanice si diupa efectuarea probei de presiune.

Prior to the coating of the tube bundle all mechanical work must be completed and the pressure test passed.

2.3 Zonele periferice 2.3 Edge zones Pentru evitarea unor infiltratii in stratul de protectie, suprafetele de etansare din material 1.4571 din toate zonele periferice se vor suda cu un strat tampon supraaliat. (vezi anexa 3; fig. 2, 3, 4, 5 si 6.)

To avoid seeping below the surface protection, the seal surfaces of all edge zones of the surface protection must be welded over with steel grade 1.4571 with over-alloyed buffer layer. (see 0, fig. 2, 3, 4, 5 and 6)

Suprapunerea stratului de acoperire cu stratul de placare se verifica dupa executie n ceea ce priveste realizarea corespunzatoare (suficienta la suprapunere)

After manufacturing the overlapping of the coating with the cladding must be checked for proper execution and sufficient overlapping.


2.4 Asamblarea, repararea defectelor 2.4 Assembly, repair of damages La asamblarea pieselor acoperite se va acorda o atente deosebita. naintea asamblarii, se vor verifica toate piesele . Se vor repara punctele cu defecte i se vor inspecta inaintea montajului.

Special care is required during the assembly of coated individual parts. Before assembly, it is essential that all parts are inspected; flaws must be repaired and after being inspected the parts must be approved for assembly.

Pentru manipularea pieselor acoperite se vor folosi chingi acoperite cu material plastic ( n nici un caz lanturi !), rezistente la produse petroliere si cu latime suficientapentru a evita deteriorarile.

Organic-coated belts (no chains, etc.) must be used for manipulation of the coated parts; these must be benzine- and oil-resistant and have appropriate width to prevent damage.

Pasitul pe suprafetele acoperite cu materiale plastice se va face numai cu talpici de protectie, rezistente la produse petroliere.

Organic coated surfaces may only be stepped on with protective mats, which must be benzine and oil-resistant.

Sculele trebuie prevazute cu nvelisuri moi. Tools must have soft coverings drawn over them.

Toate lucrarile de sudura la schimbatorul de caldura trebuie terminate nainte de montarea pieselor acoperite.

All welding work on all parts of the heat exchanger must be completed prior to fitting the coated parts.

Se vor semnala cele mai mici defecte mecanice si se va discuta cu managerul de proiect OMV / Petrom, daca aceste defecte se pot remedia la fata locului.

Defectele mai ample se vor repara n uzina producatoare.

Even the smallest of mechanical damages and flaws must be reported and it must be decided in cooperation with the OMV Petrom project manager whether this damage can be repaired on location. Larger damages to the surface protection shall be repaired at the manufacturers plant.

3.0 VERIFICARE SI RECEPTIE 3.0 INSPECTION AND ACCEPTANCE

3.1 Verificarea ncarcarilor prin sudare 3.1 Inspection of the build-up welding ncarcarile prin sudare prescrise se vor verifica daca nu prezinta fisuri de suprafata.

Pentru procedeul de sudura utilizat se va face o autorizare care sa demonstreze ca in acest proces de depunere prin sudura s-a obtinut o structura metalografica adecvata.

The prescribed build-up welding must be subjected to a surface crack inspection. The welding procedure to be applied has to be approved by a welding procedure test to verify that the build-up welding achieves an accurate structure.

3.2 Verificarea straturilor organice de acoperire

3.2 Inspection of the organic coating

Straturile de acoperire se vor supune urmatoarelor verificari:

Verificare vizuala Verificarea grosimii stratului Verificarea in vederea indentificarii eventualilor

pori

The coatings must be subjected to the following tests:

Visual test Layer thickness test Pore test


3.2.1 Control vizual 3.2.1 Visual test Toate acoperirile se vor controla vizual atat pentru acoperirile de interior cat si pentru cele de exterior.

Tevile acoperite pe interior se controleaza cu aparate tip endoscop. Defecte ca: bule de aer, incluziuni, locuri incomplet acoperite sau deteriorari mecanice se vor mentiona ntr-un protocol si se va trece la eliminarea lor

All coatings must be visually tested on the outside and inside. For tubes coated on the inside the test must be performed with hollow-object testing devices. Flaws such as bubbles, inclusions, incompletely covered areas, mechanical damage must be recorded in a report and their repair initiated.

3.2.2 Verificarea grosimii stratului 3.2.2 Layer thickness test Grosimea stratului organic de acoperire se stabileste prin procedee magnetice sau electrice, n functie de tipul materialului de baza.

The thickness of the organic coatings must be determined with magnetic or electrical (eddy current device) processes, depending on the type of base material.

3.2.3 Verificarea in vederea identificarii eventualilor pori

3.2.3 Pore test

Controlarea stratului in ceea ce priveste posibilitatea existentei unor pori se executa prin verificare uscata (la strapungere).

Pentru aceasta verificare se ntocmeste un protocol detaliat, care trebuie sa contina date despre reparatii, eliminarea defectelor si trebuie sa cuprinda nota de acceptare pentru montaj.

Se vor verifica tolerantele care trebuie respectate.

Protocolul face parte din documentatia de Livrare.

The test of the coating for pores must be performed with a dry test (puncture test). A detailed acceptance report must be made regarding this test. This report shall state information on repairs and an approval seal. Compliance with tolerances is to be checked. This report is part of the documentation to be delivered.

4.0 EXPEDIERE 4.0 DELIVERY AND DISPATCH Piesele separate acoperite se vor marca pentru expediere ( prin aplicarea unei etichete cu observatia ATENTIE A NU SE DETERIORA ACOPERIRE CU MATERIAL PLASTIC ) si se vor ambala astfel nct sa nu se deterioreze la transport si sa fie asigurata protectia pentru manipulare la montaj.

For the dispatch coated individual parts must be labelled (attachment of a notice sign with the text CAREFUL DO NOT DAMAGE - ORGANIC COATING") and packaged so that they cannot be damaged during transport and such that significant protection is ensured for manipulation during installation.

n cazul fasciculelor de tevi acoperite se vor folosi sanii de transport. Ele trebuie astfel construite,nct la transport sa nu se produca deteriorari ale fascicolului de tevi sau ale acoperirii de material plastic

For coated tube bundles, transport sleds must definitely be used. These shall be built such that no damage to the tube bundles and organic coatings can occur during transport.

5.0 DEPOZITARE 5.0 STORAGE Depozitarea ndelungata a pieselor acoperite, n special a pieselor de schimb, trebuie sa se faca numai n spatii acoperite.
