kelly hose suppliers made in china

Flexible drilling rubber hoses play an important role in petroleum extraction. They should suffer high operating pressure, extreme operating temperature, abrasion and other inferior elements. Our special compounded synthetic rubber has been proven an effective and economical way to reject these problems. All our oilfield drill hoses are manufactured as API 7K or other related specifications.

Steel cable reinforcement loads most working pressure up to 15,000psi. The wires are usually zinc-plating or copper platting to improve steel wire resistant against rust and corrosion. Due to the thick reinforcement, the hoses should be handled or stored in correct way to avoid kicking or crushing. They will substantially decrease their rated operating pressure.

Rotary hose, Kelly hose, cement hose, mud hose, jumper hose and vibrator hose and choke & kill hoses are the most popular oilfield rubber hoses. They convey high-pressure drilling fluid from one place to another. Many end fittings are provided to satisfy different applications. Most end fittings are made according to API standards. Special order is also available.

Drilling hose(rotary hose)made according to API 7K spec, applies for flexible hose connection between the top of oil drilling stand pipe and vertical moved swivel joint in well drilling, well cementing, work-over and down-hole servicing operation. drilling hose is also used to adjust the installation mistake between drilling pipe line and stand pipe to avoid shake, sometimes to transfer high pressure oil and water base mud with the lowest aniline point of 60°C from the swivel pipe in high pressure, and down-hole operation high medium such as water, oil etc, drilling rotary hose can be used for prefect work too.

As China’s first API authorized manufacturer of oilfield hoses, Jingbo has got the certificates of API Spec 7K-0376, API Spec 16C-0275, API Spec 16D-0109, API Spec Q1-2085 and API ISO9001-2008.

Jingbo exports hoses to more than 20 countries. Such as the USA, Russia, Brazil, Argentina, Iran, UAE, etc. We are ready to be your long term reliable partner of oilfield hoses.

SKIVING Skiving a hydraulic hose is the process of using special equipment and tooling to shave a predetermined depth of the OD and ID of the hose. Some medium pressure hose fittings require only external skiving (or single skive) in order for the ferrule and hose fitting to mate correctly.

There are a number of factors to consider when selecting hydraulic hose fitting types, including the compatibility of the fitting to the hose, one or two piece design and the correct assembly.

Each type of hydraulic hose fitting connects to a tube, hose or a port. A port connection is part of a component, such as a manifold or pump. All types of hydraulic hose fittings are made to industrial standards, the most common of which are:

The safety, reliability and service life of a system are only as good as its transfer lines and connections. Tube fittings and adapters are critical components in tubing and hose connections, valves, hydraulic systems, pumps and cylinders. The right connection of the fitting and tube or hose provides outstanding leak free service life, even at high temperatures, pressures, corrosive environments and steady vibration cycles.

Of course, those do still exist. And they have their place too, in situations where you might need something that tough. We recommend one made from the traditional rubber, in fact, as well as the best in class for other situations.

Many people who have used a Flexilla garden hose swear it’s the greatest ever made. It also does well in expert testing, where it lives up to its kink-free claims.

The manufacturer says the material is lead-free and drinking water safe, although it’s not tested or certified by any of the agencies that verify those claims. They also say it can withstand temperatures from -40 to 150°F, and owners attest that it holds up well in hot temperatures.

Need a tough garden hose for washing your car, for powering a pressure washer, or that can live outside during the worst winters? Then the Craftsman Premium offering should be at the top of your list.

This is a popular pick for landscape professionals and those who need something that can stand up to light commercial applications, such as mixing cement.

This product is as durable as they come. We saw a number of comments from owners who ran theirs over with their car (accidentally, of course) and reported that the couplings didn’t crush, and the hose was oblivious.

If you’re looking for something that’s a little easier on the wallet, but still easy to wrangle in a small garden, we recommend the Gatorhyde Coiled Garden Hose.

This setup includes the reel, a 9/16-inch diameter, 82-foot hose with a seven function nozzle, and a 6.5-foot leader hose. Many owners like that 82-foot length, saying it’s a nice alternative to having to choose between that standard 50 or 100 feet.

The Hoselink is intended to be wall-mounted and, when mounted, the reel can swivel 180 degrees. You will need a drill for the installation, so keep that in mind.

Users say the reel is easy to install and use, and the hose retracts very easily with the automatic rewind. Many also note that they’ve had one for several years and it is holding up well. The whole setup weighs 30 pounds.

The hose and reel are made from PVC and polypropylene with brass couplers, and stainless steel and plastic fittings. It is not food grade, so it’s probably best to avoid filling the dog’s bowl with this one.

The hose in integral to the reel and cannot be replaced. One nice feature is that the reel keeps the hose protected even in extreme weather conditions.

It’s not as sturdy as a traditional model, and some users complain of leakage and deterioration. However, the latter issue seemed to be more of a problem when the hose was left out continually, rather than rolling it up and storing it after each use.

Ideal for watering delicate new grasses or long, narrow areas like the side of a house, the Gilmour Vinyl Sprinkler Hose is a very versatile choice that can also function as a soaker. Just position it with the white side up for sprinkling, and the white side down for soaking.

The fittings are nickel plated. It measures the standard 5/8 inch in diameter. It only comes in a 50-foot length, but you can attach up to three hoses. Gilmour offers a lifetime warranty.
