for which the particle momentum can be calculated as 2h/L from de broglie relation

Whereas from energy quantisation relation p=nh/2L where n is the state integer,for n=2 ,p=h/L

Why does so happen?

Particle-in-a-box eigenstates are not eigenstates of the momentum operator, therefore you can't say that it corresponds to a given value of momentum.Whereas from energy quantisation relation p=nh/2L where n is the state integer,for n=2 ,p=h/L
