API STC Casing Couplings

We provide STC casing coulings from 4-1/2″ to 20″, in grade J55, K55, N80, L80 and P110.

Threads are used as mechanical means to hold the neighboring joints together during axial tension or compression. For all casing sizes, the threads are not intended to be leak resistant when made up.

The round-thread (STC or LTC) casing-joint strength is given as the lesser of the fracture strength of the pin and the jump-out strength.

2. Standard: API 5CT/5B
3. Type: STC
4. Grade:J55/K55/N80/L80/P110

Q: something odd, yet makes sense. oil sponge, ocean speed bump, future jacket. stuff like that.): Overpasses, potholes, traffic jams, and speedways. You park in a driveway and drive on a parkway. And some days when you see flashing lights in the rear view mirror, you just want to pull over and say oh, sh**.

Q: I am building a small rolling road to test my nitro RC cars out and i am trying to figure out the best way to simulate a realistic resisance for the engine and transmission to work againstany ideas?: This answer is for those who live in Australia. There is an Australian Standard that governs the maintenance of fire extinguishers - AS1851. To comply, you need a tag to record the six monthly checks. Compliance is not necessary in a home situation, only in a commercial environment, or in a strata housing block. The tag is stamped on the month/year it is inspected, with the number 1 through to 5 depending on the nature of the inspection. Local Government enforce the AS1851. An unstamped extinguisher tag might be OK for the first 6 months (if you can prove when you bought it), but it is better if it is stamped, so there is no question that it is compliant. Extinguishers that are older than 5 years must be emptied and pressure tested. Its often cheaper to replace them

Q: Right, me and my bf went for a walk and i text my friend and then left my phone on a wall. right next to the wall were gardens, 4 kids were on a trampoline staring at us. when i got home i realised i had forgotten my phone. i ran back to the spot and it was gone, but the children weren't in the garden. we rang it over and over, once someone answered made a screaching sound and hung up the phone. we then went to knock on their door and ask if they had seen it, they said no. now i still dont have my phone, is there anyway i can track it? where i last had it wasnt far away. it has now died, so when we ring it, it goes straight to voicemail. HELP?!?!: judging from the name of the hand shake i am guessing its a very rough handshake that breaks your bones? lol

Q: Is there special jackets For You when You become a weather spotter? And if any of You are a weather spotter, what do i need to know before i go to classes?: u shouldnt care wat they think. get it. theyre just being stupid

Q: Well here's da deal, I've done quite alot of research on this and i know that da XI2 is hands down best. but im a college student in north Dakota(were it snows and have ice like crazy!) i wana spend on this smartly. If i go with a set of generals im gona save like $130 but i want good traction too since i put a decent amount of time on the road and my car is lexus sc300 RWD (i know what u thinking but It's the only 1 i have and love it!). My concern is will a set of general STUDDABLES( altimax arctics without studs) will deliver what i want? i drive fast but since it started to snow couple of days ago im driving insanely slow and still i have problem since i have all season tires on it now. i want to drive in a decent pace in city and at least 70-80 on highway. Guys what do you think??? that extra $130 will be worth while spending to help my driving? or i can getaway with a set or cheap generals???: some local codes require flexible attatchments and some forbid flexible attatchments. unless you find someone familiar with local code (a plumber) then you have to call your city mechanical inspector and ask him.

Q: what is &curved space&?: 1. The product. Are they making a product that has a market? They can make the best iron pipe fittings in the world, but if every body is using plastic pipe fittings, that company is not long for this world. 2. Customer base. Is 90% of their business generated by a single customer?? Stay clear! If that company would have financial difficulty, it could wreck the best companies.and if it were to lose that customer, lights out! 3. Debt to equity. Is the co heavy with long term debt, and are accounts payable current? Then, the co has adequate cash flow to pay its bills. 4. Legal issues. Not necessarily lawsuits, but are they disposing of waste in a questionable manner? Is their facility surrounded by fields that are giving way to housing developments? true, the co was there first, but all it takes in one person buying a new house who is going to complain about heavy trucks going in and out of your property. 4. Are their workers represented by a Union. Non union work forces are more flexible. 5. ifs there room for future expansion? There are others, but these , to me, are very important.

Q: A week ago someone broke into my 1991 Nissan Sentra and tried to steal it. They damaged the ignition cylinder and it is CRAZY expensive to replace for this car. Even if replacement was an option, I cannot remove the lock cylinder because they ruined it and I can't put the key in (at all) to turn it to the accessory position (needed to remove the cylinder, I've done a lot of research). My primary problem is: How can I remove the cylinder without the key? I've seen many topics about drilling it out, but I need specifics. OR How can I bypass the Steering wheel lock? (We bypassed the ignition cylinder, but the damn wheel was locked) It's been over a week now and the car has almost gotten tickets for sitting in the same area by the city. If you have a solution, please email me. I understand this is a strange situation, but the car must be moved ASAP into our driveway before we get fines, and have the money to pay a locksmith. THANKS!!: You are not confused. With the exception of tubing, pipe of any kind is measured by the inside diameter. But look at any pipe chart and you will see that dimension is approximate for every single type. For example, a schedule 80 steel or PVC pipe has a thicker wall so the ID is a bit smaller than that of schedule forty. The same thing applies to irrigation or drain pipe. . Standard fittings will fit different schedule pipe of the same type. PVC and CPVC are deliberately made different (PVC being a bit bigger OD and ID than CPVC than the designated size) to keep people tying them together in the same run. A piece of Half inch CPVC will actually slide inside a piece of half inch PVC.

Q: why experience is more valuable than formal knowledge?: Cast iron drain pipe. Check with a plummer for proper fix. They do make fittings for cutting out damage and replacing with other product.

Q: What's the difference between pipe repair device and clamp type flexible pipe joint?: The clamp type flexible pipe joint needs welding, but the pressure range is big, 10-220 kilograms of pressure can bear, and it has the limit function, at the same time provides the effective flexibility and the corner to the limit. The utility model is generally used on pipelines of more than 16 kilograms, and the cost is greatly lower than the flanges and the telescopic devices.

Q: I am making a story book for children and I want some ideas of things that can burn in fire I have some in mind but looking for some ideas thank you: If you are trying to fix a leak in copper water pipes, (say they froze and split, or leaking at bad solder joint, etc) the best thing to do cut out the bad part and re-solder new pipe/fittings as necessary. If it is just one tiny pin-hole and it is in a place where it would be really hard to re-solder, they do have these metal clamp-like cuff things that mash a piece of rubber sheeting over the hole.
