Blasting Hose Questions?

edjohnson

From what I've read, seems like 50' is the stanard for blasting hose. I could use at least 75' and 100' would be better. I have large houses that are hard (not impossible) to get the pot in the back yard. Are there disadvantages to longer hose? Also, does it matter what size the supply hose is(compressor). I know it has to be at least the same size as the blast hose and/or nozzle, but is bigger better? The compressors I have used have 3/4 outlets (I think) so I'm thinking that increasing the hose wouldn't matter. Am I correct or way off.
Most of my work is chemical stripping so have alot to learn about blasting, but enjoying this board and look forward to learning.
Thanks,
Doug

Longer the hose, more PSI you lose. For every PSI you drop, you loose 1.5% in productivity. I use a 210 CFM compressor, my pot has a 1.5" air inlet, so i use 1.5" air hose.

Get your hands on a Clemco Blast Off 2 book. This will tell you everything that you need to know about proper hose sizing. I have run over over 500' of blast hose before for four blasters. That is 2,500 ft of hose and still maintained over 100lb. of pressure at the nozzle. It is all about proper sizing and having enough air volume to push what you need. With a 375cfm air compressor with say 125psi at the compressor, you should be able to run 200' of blast hose easy for the type of work that you are doing. If you would like more information, just give me a call anytime. Be glad to help.

Sincerely,

Eddie,get your hands on what u are doing, not a book. piece of cake 75' bullhose 25' whip hose.whatever u do go with at least a 25' whip.cfm to me is most important,the more the merrier.if u dont get it now,u will latter.

painter213

Why would you use a Whip hose? What diam. would this Bull hose and Whip hose be? Why learn from making mistakes, when you can look at a respected book in the industry and save some pain from making mistakes that can cost you money. Books of the industry is a valuble tool to have. If you don't use them, then you should. If you think books are not important, then you have a lot to learn. Sandblasting is not just showing up and picking up a hose. Ed Johnson, I will be looking for your call after the Christmas rush. I will be back to work on Friday, helping set up on the next Fuel tank lining project. Give me a call anytime.

OK,
I may be sorry to ask this but,...............what is a bull hose and a whip hose.
Bennie,
Where do I find the blast off 2 book?

FOUND the BOOK......THANKS!!

U crazy not to use a whip hose. better control of the monster @ 375 cfm 125psi,are u sure u done this before.books are a good thing as i have said before.but when it comes to actual blasting .4 men @ 500' is nothing to brag about Happy Xmas.

I have always ran 1 1/4" blast hose all the way to the blast nozzle IBSOCAL. Our last 50' of blast hose is a Supa Hose that flexes like a 1" blast hose. This way we do not restrict our air and abrasive flow. And I do not use little 375's and 125psi. Us real men of abrasive blasting use 1600CFM @ 150psi. We like to get in and get our jobs done quickly. We also use #8 nozzles as well. We don't use Whips either. Whips reduces your volume output and lowers production numbers. I have been in the Industrial Coatings Industry for over 20 years and I have been sandblasting since I was 13. My father was a Industrial Professional for 47 years. So, I think I have done this before. It's not my first rodeo. I have been on a many water tanks, steel mills and high transmission towers in my experiance since getting out of school. Since 13, my summer job was sandblasting small stuff around the shop that people would drop off to have blasted. My knowledge of the business comes from first hand experiance. I feel as though I have earned it and I have worked in many area's of the contry and been to great heights to get the work done. I myself do not get to get behind the blast hose much anymore, but I can still hang in there and do the work. Just like riding a bike. Never forget. On the part of 500'. If you was using a 375 @ 125psi, with a vertical feet of 500'. You would not have very much pressure at the nozzle due to gravity of trying to push the air stream and the abrasive at that height. At 500' you would need at least 400' of 1 1/2'' blast hose, step down to 1 1/4" blast hose to the nozzle. You would still experiance several pound of pressure loss at the nozzle, but you would have enough to work with. I would recommed the use of full Flow hose couplings as well. These couplings are better suited for running hoses longer distances. They have a part number of a Q-AL5. Anyway, I have ranted enough here. Hope everyone has a Merry Christmas. Be Safe.

No man, I have more. I guess the most CFM I have had on a job was around 5,000CFM in all. We were doing a couple of Lock Gates for the Corp. of Enegineers on the Ohio River and we were running 14 blast nozzles. We ran Three Can Sands. One with five outlets, one with seven, and the other with just two. I just take my work serious is all. I have come up through the hard knocks all the way up. I hold several certifications through SSPC, PDA, and NACE and no one just gave them to me. I had to earn them. I was raised in a family of industrial painters and cut my teeth on Bridges and water tanks. That is a tuff life. I cannot travel anywhere either by car or plane without looking out for water tanks and counting them. Old habits are hard to break. By the way, is there anyone here that will be attending the PACE confernce in New Orleans in February? My conference schedule starts next month in New Mexico and runs thru March, so I will be all over the place gearing up for more contacts for work. If you are, let me know. It would be nice to meet some of you sometime.

I just noticed both of U hot dogs names start with a P, P213 and P2414.
U P2414 are the real Trip that i was refering to
anyway P213 your a trip too

ibsocal

Industrial Blasting is a tuff way to make a living no doubt about it my Bro's.Benny did u just shoot your load with 14 men and 5000cfm on A job is that it. Benny most people know U have to pay big bucks for the certs so they usually give u lots of books to study so U can pass the tests. sure u have to have some knowledge in the trade but if u got the cash they will give the test to anybody in the trade that meets the basic requirements.I know quite a few nace guys and gals that sometimes would make me say how did they get it,(nace OR any cert) but i just told u how some do PAY TO PLAY TEST , STUDY BOOK AND PASS TEST. GET CERT # AND DONT BE LATE WITH MEMBERSHIP FEE.Your right, they dont just give them away and old habits are hard to break.Later P213

Ibesocal, what do I have too prove to you? I know that you have worked on the ship yards. I have not been in charge of the huge projects that you have been, but **** look up painters pics. I dont post pics but hey I would think that you may show a small amount of respect. I guess that may come from me being an asshole last year but let us try to agree on something for a period of time, we know what we are talking about. lets engage each other and talk some .

user20594

Ibesocal, I do have one other thing to say to you. I have read your other threads in the library of contractor talk. You once said I probably hate my parents too, I guess if I were in a union that would make you and I a brotherhood....
