COATINGSPRO NOVEMBER 2015 61 To keep the tank from becoming a fading beauty, the A lpine crew allowed the Series 27 to set up (at a minimum of 12–15 hours at 35° F, or 2° C), switched to #313 tips, and used their Graco Kings to apply a 2- to 3-mil (50.8–76.2 microns) DFT single pass of Tnemec 1075U aliphatic acrylic polyurethane. Tnemec 1075U contains ultraviolet (UV) light absorbers for enhanced color and gloss retention, according to the product's data sheet. Get Skinny! Make no bones about it, A lpine worked hard to get this project back on track. Te crew worked around an array of communi- cation transmitters atop the tank, used brute strength to haul blast and spray gear up and down the structure, removed and properly disposed of the existing lead-based coating system, and overcame a massive containment blowout. But A lpine had yet to face its biggest challenge! To complete this 180-day project, the crew needed to abrasive blast and coat the interior of the tower's central dry riser. Specs called for a NACE No. 3/SSPC-SP-6 commercial blast prior to spray application of Tnemec Series N140 polyamidoam- ine epoxy. Working inside any 10-foot-diameter (3.0 m) vertical riser is tough, but where the top of this riser meets the bottom of the water tank, it squeezes down to 36 inches (91.4 cm) to provide a way for MWD personnel to access the roof. Yes! Tere's a ladder inside this three-foot-diameter (0.9 m) pipe and MWD supervisors thought nothing of sending one of their more slender maintenance workers to climb it — all the while surrounded by millions of tons of water. Even with the tank now drained, the pressure was on the A lpine crew to get skinny! "Te most difcult part of this job was the 50-foot [15.2 m] run inside the saucer where the access tube narrows," said Scaturro. "It's hard to imagine how much ricochet that sandblast- ing creates in such tight quarters. Te guys needed plenty of leather and heavy cotton clothing to keep from getting chewed up. Tey wore Bullard air-supplied respirators and basically clipped their harnesses to the steel ladder rungs, leaned back, and went at it. It wasn't an easy job, but it had to be done." Once it was prepped, the A lpine crew was able to apply the coating. Tey applied two coats for a total DFT of 4–8 mils (101.6–203.2 microns). Beauty Only Skin Deep As Scaturro said, the project wasn't easy. But A lpine completed it on time. Gonnella happily reported that he has not received a single comment about the tank. "But that's a good thing," he said. " Tnemec has a Tank of the Year Contest where people across the countr y get to vote on their tanks. T his tank may never w in an award, but it's like a beige Mercedes Benz driving dow n a highway. It's not going to turn heads, but it's going to last for years and years." A lpine is proud of this project, too. It was a large job, with many hurdles to overcome, but the eight-man crew prevailed. "Te owner is happy with the outcome, and that's what matters most," said Scaturro. "Our guys really stepped it up when we got behind schedule, and that makes all of us proud!" How proud is Scaturro? He keeps a glossy photo of the completed Massapequa water tank project hanging in his ofce. It serves as a reminder that beauty is only skin deep! CP VENDOR TEAM Allmand Brothers, Inc.
