Seamless steel pipe manufacturers to share: What are the differences between elbow and elbow

Seamless steel pipe manufacturers to share: What is the difference between elbows and elbows Elbows and elbows the most basic difference is the elbows relative to elbows is relatively short. R = 1 times to 2 times the elbow, and then a large multiple is called elbow. In the production process on the cold elbow can be used straight pipe bending machine bending, one-time completion without the second corrosion. But the elbow to the factory custom, anti-corrosion to do, ordering a long period. Elbow prices higher than the elbow but the cost is much higher than the elbow, without corrosion of the elbow is easy to damage the well-known, but because of the low price of some less demanding projects are used very much. Elbow to manufacturers custom, to anti-corrosion, long order cycle. Cold-formed pipe can be bent with a ready-made straight pipe bender. One-time completion of the second anticorrosive. Cold-formed pipe construction process has a petroleum standard, West-East gas transmission has enterprise standards. However, the use of elbows elbows are open area, only consider the cost, the elbow heat simmer, elbow can be cold, of course, the high cost of elbow. Sometimes narrow sections must use elbows, such as the stone section of the trench, because the bend radius of curvature is small, usually 6D, and elbow 40D. (Source: )

Water Reducer mainly is used for cement in construction field.  Used for and widely for self-cured, vapor-cured concrete and its formulations. At the early stageof application, extremely prominent effects are shown. As the result, the modulus and site utilization can be drastically, the procedure of vapor cure is omitted in peak-heatsummer days. Statistically 40-60 metric tons of coal will be preserved when a metric ton of the material is consumed.The new raw material is researched and produced by ourselves, which is mainly used in theproduction of polycarboxylate superplasticizer products.   

Remarkable plasticity:  as a condition of blending where amount of cement and collapsibility are fixed aforehand, mixing water can be decreased by 18-28% when it is admised with reinforced concrete at 0.5-1.0%. Ststistically, compression strendth on the 1st day, the 3rd day and the 28th day after single application is increased by 60-90% and 25-60% respectively when it is added at standard blend dosage. As the result, compression strength, tensile strength, bucking strgth and modulus of elasticity will be improved to some extent.
