ASME U‑Tube Shell & Tube Heat Exchanger TEMA BEU Class R for Petrochemical Process Duty

YUHONG produce the heavy‑duty U‑tube bundle shell‑and‑tube heat exchangers engineered expressly for continuous, high‑severity process service in refinery and petrochemical environments. Every pressure‑boundary component — shell, channel, tubesheets, nozzles, and reinforcing pads — is mechanically designed, fabricated, inspected, and stamped in full compliance with the ASME Boiler & Pressure Vessel Code, Section VIII, Division 1 (ASME VIII‑1), integrated with TEMA Class R mechanical standards and API 660 where refinery‑specific requirements apply.

Design Code & Governing Standards

Primary Design Code	ASME BPVC Section VIII, Division 1
Mechanical / Geometry Standard	TEMA — Class R
Industry Practice Supplement	API 660 / API 661
Welding Qualification	ASME Section IX
Flange / Nozzle Dimensioning	ASME B16.5 (flanges), ASME B16.47 (large‑diam.), ASME B31.3 (piping interface loads considered in nozzle reinforcement per UG‑37)
Stamp	ASME "U" Stamp

Welding & NDT Regime (ASME VIII‑1 / Section IX)

Weld Category	Typical NDT Requirement
Long. & circ. shell seams (pressure)	RT per UW‑51 (typically 100 % for Class R), or UT where approved
Nozzle‑to‑shell / insert welds	MT or PT (surface crack detection) per UW‑50 / project spec
Tube‑to‑tubesheet seal welds	PT or MT 100 %

Core Pressure‑Boundary Construction

Formed from normalized carbon steel plate (typically SA‑516 Gr. 60/70) or alloy/clad construction where process chemistry dictates.
Longitudinal and circumferential seams are full‑penetration, radio graphed per project NDT matrix (ASME VIII‑1, UW‑51).
Minimum thickness established per UG‑27 / UG‑16(b) plus stated corrosion allowance, plus forming thinning tolerance.
Bolted channel cover or integral A head depending on service access requirements — both designed per UG‑34 (flat heads) and UG‑32 (formed heads).
Gasket contact surfaces machined to finish compatible with spiral‑wound or ring‑joint gaskets, selected per ASME pressure‑temperature rating.
U‑tube tubesheet designed per ASME VIII‑1 + TEMA ligament‑efficiency method.
Unperforated rim (facing) and tube‑hole tolerance controlled to TEMA Class R limits.
Where galvanic or corrosion severity requires: clad overlayapplied per a Section IX‑qualified WPS, with dilution and interpass temperature controlled; overlay thickness verified by UT/PT.
Tubes bent to minimum bend radius ≥ 1.5 × tube OD .
Tube‑to‑tubesheet joint: roller‑expanded + seal weld, with the weld procedure qualified under ASME Section IX.
Baffles / support plates: segmental or disk‑and‑dough nut per thermal design; baffle spacing never < 20% of shell ID or 50 mm (TEMA); baffle hole clearance controlled to limit tube vibration and erosion.
