Brass fittings are used in plumbing and pipes. Welding the brass fitting onto the pipe is simply one other technique of soldering. Normally, you heat a parts of a joint with a propane torch. A first action is to heat a brass fitting, which could cause a fitting to expand slightly. A following can introduce in detail methods to weld brass fittings.
1. Clean the brass fitting planed to weld onto the pipe with the wire brush. Then clean the end of the pipe you??￥ll meld a fitting to, as well with steel wool or a steel brush.
2. Apply a thin coat of flux to the surfaces of both a pipe and a brass fitting,. Set a fitting onto the pipe and give a fitting a twist to know that a flux spreads evenly between a two.
3. Heat a base of the brass fitting with a propane torch. Move a torch in a circular motion to assure that heat is applied evenly.
4. Stick a welding wire into the joint when the flux begins to bubble. If the brass fitting is hot enough, a solder can melt and flow into the joint.
5. Remove a torch from a brass fitting when the solder flows into the joint. Let a fitting cool before continuing. The solder should return to a solid state anytime a joint is properly cooled.

What's a Reducing Tee?
A theory of reducing tee: the diameter of branch pipe is different from the other two. The branches with same diameter are named as straight tee. Reducing tee are popular in a building and maintenance industries including petrochemical, oil and purely natural gas, liquefied petroleum gas, fertilizer, power plants, nuclear power, shipbuilding, paper, pharmaceutical, food sanitation, urban building projects.
The expression of reducing tee is as follows: For straight tee, ???T3?? tee suggests outer diameter of straight tee is 3 inches; for reducing tee, ???T4 ?¨￠ 4 ?¨￠ 3.5?? suggests a reducing tee with 4-inch same diameter and 3.5-inch various diameter.
The material of reducing tee is generally 10 # 20 # A3 Q235A 20g 16Mn ASTM A234 ASTM A105 ASTMA403. And, a outer diameter range of reducing tee is 2.5 ??à to 60??; the welding tee is from 26 ??à to 60??, whose thickness is 28 to 60mm.
The pressure rating of reducing tee: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS.
The industry requirements of that reducing tee is relatively high, and the highest pressure are able to reach to 600 kilograms, when a water pressure is low including 16 kg.

Ways to Choose the Perfect Industrial Casters
You will find several diverse aspects determine a choice of industrial casters, a crucial is some adequate for your usage. These are several valuable considerations for you selecting industrial casters.
?? carrying capability. A carry ability decides a carrying weight and wheels??￥ sizes, and effects a rotation of industrial casters. For example, ball bearings for more than 180 kg heavier load requirements.
?? Use site factors. Pick the huge enough industrial casters to fit round the rift scene. Also consider use a road capacity, obstacles and other elements.
?? Unique situations. Each industrial caster are able to be adaptable to distinct working surroundings, select the greatest one to adapt to special situation. For example, a traditional rubber are able to not be with acid oil and chemicals; if you wish to apply different particular conditions, high-tech polyurethane rubber tire, plastic wheel and steel wheel is a excellent selection.
?? Rotation flexibility. The larger industrial casters may make apply of less effort. Ball bearings are able to carry heavier loads while ball bearing rotation with lighter load is more flexible.
?? temperature limit. Too cold and heat may cause trouble on a lot of wheels, in case utilize the special green grease, industrial casters will be adaptable to the temperature of -40 ?? to 165 ??.

Pay Attention to Your Alloy Wheels on a Cars
With China fast financial, the increasing popularity of cars brings on increase alloy wheels needs. A few owners upgrade their cars with bigger alloy wheels to exchange old wheels. A tire diameter remains a same, larger law flat tire so that the car horizontal swing is smaller to enhance stability; finally a cars lose their comfort.
1, wash away the sand and dirt conveniently attached on the alloy wheel surface. Otherwise, a alloy wheels surface could be quick to corrosion and damage.
2, clean alloy wheels like inside and outside surface, especially with anti-acid cleaner. Preferably wax a wheels once every 2 months to, which could prolong the life of a alloy wheels.

Steel Casting Parts Melting
In general, a melting of steel casting parts use open hearth, electric arc furnace and induction furnace and so on. A open hearth is characterized by great capacity, get usage of waste steel, and accurately control a composition of the steel casting parts quality. It is some used for melting high quality steel liquid.
Three-phase electric arc furnace and blowing-out are easy to operate to melt steel casting, and they can get sure that a composition and quality of liquid steel, a less stringent requirements. The furnaces, the popular products to produce a steel casting parts, can refine high-quality steel, high alloy steel and particular steel.
In addition, use frequency or intermediate times induction furnace, to melt the variety of high alloy steels low carbon steel and steel casting parts and so on. As fast melting, small alloying elements burning and energy consumption, and high quality molten steel which have small impurity, a induction furnaces are perfect for small-scale steel casting workshops.
