What are Forged Pipe Fittings?

Posted on by

Introduction:

 

Forged Pipe Fittings (Thread Fittings and Socket Weld Fittings) are made in accordance to ASME (American Society of Mechanical Engineers) B16.11, MSS-SP-79\ 83\ 95\97 and BS3799 standards, and are used to connect nominal bore schedule pipes and pipelines. The applications range from chemical, petrochemical, power generation and OEM manufacturing industry as well other applications where vibration, high pressure or extremely corrosive conditions exist.

 

Material:

 

Forged pipe fittings are generally available in two materials: Carbon Steel (ASTM A105 material spec), and Stainless Steel SS316 (ASTM A182 material spec). The surface of carbon steel A105 forged pipe fittings may be further reinforced against corrosion through galvanizing. This is an optional add-on which customers may include at an additional cost.

 

Pressure Rating and Size Range:

 

Fittings come in a variety of classes and material grades for any application. The fittings are available in 2000lbs, 3000lbs, 6000lbs, and 9000lbs. Although class 2,000 and 9,000 fittings exist, these are rarely used and class 3,000 and 6,000 remain the more common class of fittings used. Sizes of forged fittings typically range from 1/8” (DN6) up to 4” (DN100). And reducing sizes are available for common parts like couplings, tees, hex bushings and nipples.

 

Connection Types:

 

Class 3,000 and 6,000 forged pipe fittings comes in two types of connection: Socket Weld, or Threaded. NPT (National Pipe Thread) is the most common thread type although BSPP (British Standard Pipe Parallel thread) is also being available for certain parts like Full Couplings, Hex Bushings and Hex Nipples. Socket weld connection is significantly more popular than threaded since most applications call for completely sealing off a line and eliminating all possibility of leakage.

 

The fittings are normally produced with the same connection for all sides of the same fitting. That means, a socket weld fitting will have socket weld connection on all sides. Should different connection ends be required, additional machining could be possible but at a higher cost and a longer lead time.

 

Brands of Forged Fittings:

 

A highly recommended manufacturer for forged pipe fittings is Wellgrow Industries Corp... Wellgrow was established in 1987 in Taiwan, and has been well-recognized among customers worldwide for excellence in its quality and services. Under the strict control system, we have been certified with ISO 9002 and made our OEM products widely extend to international well-known manufacturers.

What’s the Difference between a Floor Nailer & Flooring Stapler?

Posted on by

So you are interested in replacing your hardwood floors, but you don’t know which tool will work best for the job? If you look for a flooring tool, you will see there are floor nailers and flooring staplers. Both tools look similar and cost the same, but which one is the one you need?

 

The answer is, either tool can work for you, but let’s explore some of the differences between a floor nailer and flooring stapler, to give you the most informed decision possible:

 

First, let’s look at each of the tools. Floor nailers are available in two variations, manual or pneumatic (air powered). You might hear a contractor refer to this tool as a flooring cleat nailer, as it most often takes cleat nails for fastening. A manual flooring nailer will require additional muscle, as it relies solely on its user’s strength. On the other hand, pneumatic floor nailers assist the user by providing additional force, when inserting a nail. Either of these tools will require a user to hit the driver head when inserting a cleat. The amount of pressure required depends on the density of the wood being installed. A thicker wood will require longer cleats, which also calls for additional force to drive the fastener.

 

Flooring Staplers are also available in manual or pneumatic variations, although manual floor staplers are typically not preferred in the construction trade. As you can see on Nail Gun Depot, electric staplers are also an option, depending on the source of power that you prefer – although pneumatic is by far the most common offering. A hardwood stapler anchors the flooring planks to the sub-floor, driving staples into the tongue of a wood plank.

 

Now that we know the tools available, let’s look at the fasteners that make the difference. As you saw above, the tools operate similarly, which means that the difference primarily lies in the fastener itself. It all boils down to nails versus staples. [Also note that you should not switch between nails and staples when installing a floor – whichever fastener you start with should be the only one used throughout the entire project.]

 

A flooring nail, or cleat, is typically offered in either “L” head or “T” head variation – check and see which variation your nail gun requires. A cleat nail offers a sharp, rigid body to grip the sub-floor firmly. It also features a smooth portion of its body, which allows for seasonal expansion and contraction of the flooring. Typically, cleat nails are available in 16 or 18 gauge – although 20 gauges are also available for certain applications. The more durable option of the two, the drawback to cleats is their cost – compared to the cost of staples.

 

Floor staples provide two-pronged fastening for hardwood flooring. Flooring staples actually provide a stronger initial grip than cleats, but do not hold as firmly when the floor expands and contracts – which can eventually lead to creaking. Another drawback to staples, they can split the tongue of flooring – especially when the plank is less than 3/4″ thick. Because staples are less costly to manufacture, they are typically the more cost-effective flooring fastener, when looking at cleats versus staples. However, you also have to consider the long-term durability of your flooring installation, when selecting between staples and nails.

 

Regardless of the flooring nailer or stapler you choose to use, it is imperative that you understand your tools prior to using. Applying too much pressure can damage your floor, while applying too little pressure can cause cleats or staples to only be driven partially, resulting in each neighboring plank to not form a tight fit, ruining the entire project.
