Tube to tube sheet fillet welding Radiographic Testing

ZTCY has studied Tube to tube sheet fillet welding Radiographic Testing for 14 years, which occupy a leading position at home and abroad.

Test all kinds of tube to tube sheet welding structure, including sealing welding, strength welding, hole welding,  in which the strength fillet welding structure allow  the tube to extend the tube plate 5mm, groove depth 7mm; We can test various tube to tube sheet welding,  in which the largest  is φ89mm, the smallest  is φ10.5mm.

We can detect a variety of materials: carbon steel, low alloy steel, austenitic stainless steel, titanium and titanium alloy, nickel and nickel alloy, zirconium and zirconium alloy, any other material.

The radiography equipment development of tube to tube sheet :

♦First generation: small focus γ – ray machine + film;

♦Second generation: rod anode X-ray machine + film;

♦Third generation: rod anode X-ray machine + CR

Detection of special tube to tube sheet weld structure – Inner hole weld, tube diameter: 16—36mm, the distance from welds to the tube surface is less than 30mm.

Performance: Detect more than 2,000 heat exchangers and filming over 200,000 during 14 years.

The T-T-RT technology and process research  of our company was rewarded the first prize in science and technology progress of the quality supervision system Jiangsu Province  and the third prize in science and technology research of AQSIQ.
